How can I achieve a similar node setup?

I'd like to have a node setup to make variations on a base texture and assign every variation to a object in a random way.
How can I do?

Thanks

In the node editor, I can't seem to find a way to delete a node. I added a node for a spotlight, but it appears those are not working nodes yet (I get errors in the console about MaxSpotlight not loading.) Then when I tried to delete the node tree (selecting the X next to the name in the info panel of the node editor) I could not get rid of it.

I did come across an error for a missing bitmap using the latest build (6/16) Seems to only be a problem with absolute paths, and maybe also connected to linking to "UVMap" Named. (one texture kept working when I didn't have a UV map assigned)

It seems once one "image file" node gets broken, then further nodes start to break. I saved and closed a file, then opened it again, and the "world" node was missing. Then another material node...

Also, working with the images in the node editor - if you change the image in the texture tab, the preview in the node editor does not update.

Hi
I wanted to ask about the version vrayblender1-2.71-54660-7ecc3f4-x86_64-windows
because I found that it is stable. However, when I want to update exporter pops up "Error retrieving the file check your connection". The same problem applies to version vrayblender-stable-2.70-54409-fc1c763-windows-x86_64 though my network is all good. Regards

I'm trying out the different rendering methods. For some reason, in this one file, progressive gets to about 6% and then does not go any further, nor does the rendering terminate. There may be some conflicting parameter that I'm not aware of (I was playing around with the settings a bit much :) ) I was able to render other scenes fine with progressive, so it may just be I mis-set something.

I have been using the nightlies. Since the 8/7 release, HDRI images don't seem to work anymore.

I loaded a previous scene, made no changes, and now there is VERY LITTLE lighting. You can start to see some semblance of reflections on glossy shaders when the illuminance map starts.

I have been using:
Image File Node---> Image Texture Node Bitmap
Environment Mapping Node Spherical-> Image Texture Node Mapping
Output-> Environment Node (All Inputs)
Output-> World Output

This has been working fine.

using vb30_2.70_54376

Looks like v/b is trying to find a IM presets menu.

search for unknown menutype VRAY_MT_preset_IM
uiItemM: not found VRAY_MT_preset_IM

Also, when I set irmap for GI, I get the following message continually:

C:\Program Files\VRayBlender-2.70b\2.70\scripts\addons\vb30\ui\properties_render
.py:775
read blend: E:\VRAY\BLENDER\basic_nodes_testing03blayered.blend
search for unknown menutype VRAY_MT_preset_IM
uiItemM: not found VRAY_MT_preset_IM

Usually I create a material library and then I assign a new material linking the material file I need.
But in this way, if I use the same method, I link just the material but not the nodetree.
If I want also the nodetree, I need to link also the nodetree.
In this way I need to do a double operation to assign a material I've already done in another file.
I'm missing something or at the moment it's the only way to do it?

Hello.

Can you make material preview working like in vb25? And if it is working now, do I have to get vray 3.0 to make it work?

In the old BfVray, when new object was selected, it would generate a new proxy object, and automatically load the preview mesh. Now, whatever option is selected, the proxy creator only makes the vrmesh file. Would it be possilbe to have the option to create or replace the new object and add an object node tree with the vray proxy node automatically?

Many Thanks!

Rob

To reproduce -

1. Link a proxy object
2. Make object local, data and materials local (L Key)
3. Save, and reopen the file.

Object node tree - should be missing (as if it has no fake user).
Material Nodes - Materials are made local and remain but the material nodes are no longer linked to the materials. Node trees are still linked to the file though (prefix 'LF' in the node tree pull down in the material node editor) but they're not attached to the material anymore.

Hope this is clear. :)

Rob

Dear Andrei,

Sorry to be putting alot on here! I'm getting a rather worrying problem this time.

When I've been modifiying adding or otherwise working on the material nodes, I regularly (around 50% of the time) get a crash when I save my blend file. The worst bit is, that it crashes and closes blender before I save my changes.

Its happened quite a few times today, using the build which saves all material nodes on save, so I think it may be that which is doing it. I have also been getting alot of crash and closes happening when trying to import materials from another file or when trying to import objects with materials on them

Unfortunately, there I haven't isolated what I have to do to get the crash, and as it closes immediately, there is no console output.

Hope this one is an easy fix, its a bit of a big issue!

Thanks again for all the work! 👍

Rob.

Hi,

This bug happens when I select a texture file node in the node editor.

The preview image which is in 'n' panel on the RHS node editor under 'Properties' does not automatically refresh when changing between different image file node in the tree.

To get the preview to update to the cureently selected file, the preview has to be resized manually.

Hope this is an easy one! :

In 3dsmax I often use the useful VrayMultiSubTex to assign different diffuse map to a single material.
In Blender+Cycles I've found a way to emulate it using the ObjectPassIndex+ a Cycles NodesGroup made by a BlenderArtist user modified by me to expand the slot available.
is there a way to emulate it with vray4Blender?
below an example of what I'm speaking about

Hello,

I tried to have displacement geometry preview, but it doesn't work. Material with Bump BRDF is working, but when I remove this function and assign displacement geometry in object node it don't affect on material preview. Is there any chance to get this preview?

It seems that each time I start v/b, each node in my saved config is enabled, even though I disabled one node in my previous session. Is it possible to saved enabled/ disabled state of DR nodes with the config file?

I've done a test trying to using the new Autosmooth but it seems that vray ignores the smoothing I see in the viewport.

I've also submitted a bug report to CG, but you may have insight into this. When I updated my build from 30504 (23949) to 30505 (24273), something got messed up with my asset paths in using DR. When I render locally, the asset paths map correctly (i.e. z:\assets\bitmap.png) but when I turn on DR, the same assets get mapped to a relative local folder that doesn't exist, something like this: \rendernode01[local-user-paths]\assets\bitmap.png

I am using the 2.70 master branch, and there is an error message that keeps being written about VRayDR.type script missing. Here is the console window screengrab

i tried this build but don't works texture uv mapped ,on vray materials,in the preview seems works but in the render don't appear, while if i uncheck uv map works
Vray is 2.0

Convert simple materials from internal, cycles and vb25.

log output:

I've been trying differrent versions of Blender last one had Hash b75fa81 from nigtlies builds. And latest exporter.

This problem was resolved but appered once again
I've uninstalled blender deleted all files from folder, installed latest nightlies and thgis pops up - Console output:
"Traceback (most recent call last):
File "C:\Program Files\VRayBlender-2.71\2.71\scripts\addons\vb30\proxy.py", li
ne 287, in execute
drSharePath = "",
TypeError: function takes at most 12 arguments (13 given)

location: :-1

location: :-1"

I've noticved that with Vray3.0 from the nightlies section, the Frame buffer always opens once and renders for a few seconds, then closes. Then it opens again and renders the full frame.

If you want to cancel a render, you always have to stop and close the frame buffer twice. If you let a frame complete, it always starts the render twice. Its not stopping any work, but it is annoying. :)

Along with this, 'Auto-Close' option has no effect, and the frame buffer must be closed manually after every render.

I also noticed (perhaps related) that in material preview mode, the terminal window continuously opens and closes.

None of the above occurs when using Vray 2.4 - could be a Vray issue?

Rob

In terms of speeding up our job, I've found useful how blender+cycles previews textures.
I'm speaking about cycles because with blender internal render engine the preview texture workflow is the same of vray4blender.
Blender&Cycles preview the texture that is selected in the node editor and this is very speedy and intuitive.
In 3dsmax, to preview a texture, you have to click a button in the material editor...so it's just one click away if you have the material editor opened.
In cycles it's nearly the same because you have just to selected the "image texture" node you want to preview.
It could be good to have the same...and it could be perfect if, using many UVmap, you can show the texture with the correct UVmpa (if defined obviously, if not you use the first UVmap)

EDIT: Sorry, probably i've already asked this. Anyway I didn't find any of this here...

If I rename a node in the node editor, the materials that reference it lose the connection to the node, I have to manually re-link the node to the material.

Dear Andrei,

Im using latest build from nightlies.

When a new material is created, (properties panel>Material list>pull down>'+'button), it duplicates the material and adds .001 etc, but also duplicates the node tree and adds .001 etc.

The newly created node tree has no fake user and therefore is lost on save and reopen.

Hope this helps.

Rob.

I can add layers, but when I click on the minus sign, I get an error and can't remove layers

error in console:

(drat, sorry, I had it copied to a file somewhere. I'm on another computer right now, I'll have to add it later if you need.)

I tried to add a "sky" node to my env background:

and got the following error and no render starting

Error: 'module' object has no attribute 'GetObjectName'

Is this an error, or is just a piece that's not in vb30 yet? No worries if it's just a to-do item. It's looking great so far!

Would it be possible to keep a manual export of the vrscene as an option? I'm getting blank renders with some of my scenes, and it's hard to figure out what is at issue. I liked being able to export my scene manually so I could look at the errors before it starts rendering.

When a camera used to render is not scale 1,1,1 (I sometimes scale the camera up to see what parts of the scene are in shot) UV mapped textures don't render properly.

The maps are either removed or scaled extremely.

I just installed new vb30(5215ab0) and found bug message when render.
I also tried to install vcredist_x64 but it still didn't work.
Screenshot: http://i.imgur.com/GIWhUAo.png

Old version vb30(490da48) works just fine.

Hi, I try use VB3,0 Render addon by clicking, but I get this reports:

I know, that I must give my build name, but this happened with all. I have two machines. With HP workstation all is great, but with my second machine something is wrong. Can you help me?

Now I can't render.
I've just start blender, enabled the vb3 addon, disabled the "Detect Vray" option, insert the path to the vray.exe "C:\Program Files\Chaos Group\V-Ray\RT for 3ds Max 2012 for x64\bin" , press Render and I've this error message.

If I use "Detect Vray" I have this error
V-Ray For Blender: Exporting data for frame 1...
V-Ray For Blender: Exporting data for frame 1 done [00:00.00]
Error: Run error: name 'debug' is not defined

The attached file contains a simple glass material that renders properly with vray 3, but not with vray 2. Looks like nothing specific for vray 3 in the setup.

Attached the images. Bland file here:

Hello everyone, I've some problems with my geometry faces control. I don't know, that this is build's or blender's error. Before 2,71 and vb30 I didn't have this problem. So I must pick Edge Split Modifier option even I've flat faces geometry with flat shading option. My blender is vrayblender3-2.71-55460-7139afe-x86_64-windows

Scene

Edge Split Modifier unpick, Shading Flat

Edge Split Modifier pick, Shading Flat

Scene with Shower Object. It is imported from SolidWorks with STL format.

Maybe I made something wrong, but it didn't happened before.

I'm trying to follow the instructions but https://nightlies.chaosgroup.com/ shows no builds for me. Tried replacing the add-on version on the chaosgroup page blender (2.69) but I get a " 'module' has no attribute 'start' " error, even if I re-start.
Mac OSX maverics.

As you can see in the image below, I have a "strange" (for me) white environment reflection. I've noted that the white color is the same I have in the node material but how can I reflect the background color instead of the "Environment Override" color I found in the VrayMtl node?

I don't know your plans about the interface but coming from the 3dsmax, I found useful to have less places as possible where tweak settings.
Vray is a big renderer full of functionalities and to set them you need many buttons, text fields and the other UI elements.
To reduce the diffusion of Vray UI elements through the Blender interface I suggest to regroup them in dedicated areas.
For example the "Vray object properties" in 3dsmax is gathered in a single windows (accessible with right mouse button when one or more objects are selected).
In Blender is it possible to position as image below?

Probably you have just tried to do it and for some reason is not a good solution, so if you think it's not a good, please let me know :)

is it possible to attach a new nodetree to the material when I create a new material?

I know that it's not difficult to press "+" to create the nodetree but one click less is always welcome.
Obviously the "+" button still remain and also the possibility to attach an existing nodetree.

Just wanted to confirm that the idea is to delete the one that is not used. When I started vb out of the box, there was an error loading vray rendering. Once I deleted the one I was not using everything worked fine.

https://dl.dropboxusercontent.com/u/12166480/Capture.JPG
What may this mean? May it cause that I'm unable to map textures onto hemisphere or areal lamps? Or are they not supported yet?

Dear Andrei,

I have been setting up a glass material in vb3, as have found some difference in the way reflection values affect a glass material.

In vb2 with vray 2.4, you use 100% balck for diffuse colour, 100% white for relection and 100% white for refraction.

Now, reflection is best set at around 30% white, otherwise it looks just like a mirror.

I thought this could be a gamma thing, or maybe another setting I've missed. It could be that vb2 was wrong and you've fixed it, or that Vray 3 works differently to Vray 2.4 now.

Its not a problem for me either way, but relfection values seem to be affecting vray differently now, so thought I'd mention it in case this highlights an issue.

Rob.

The panels are there, but when I try to use it, distributed rendering is not working. Is it still in progress?

I've downloaded this build "vrayblender-vb30-2.70-54339-4d1ec4d-windows-x86_64.exe" but I cannot use the render slave.

The render slave is the same I use successfully with 3dsmax so I think that the firewall or network communication is correct. I use the same port.

This is renderslave when starts.

I've found these typo errors into render settings.
I've checked in the others panels but it seems ok. (at least for my English language knowledge)

Hello!

When I'm using Override material function in Globals - displace map doesn`t work. It strange, because this map is connect to object, not material. And when it unpick back Override function render is black. Only visible are lights without any geometry object. Please Bdancer check this.

Regards

Message smth like "too long int to transform in to c long"

it seems that changing the fresnel value doesn't change the rendered material (at least in the material preview)

More precisely.
If you turn ON "Fresnel" (for the reflection) and change both the value in the material panel and node editor , the material preview doesn't change.
If you change the Refract IOR in the node editor, the material preview changes.
And this both with reflection fresnel ON and OFF
