Could you make the visualization of the sphere bones optional during import?

That would be great.

Also, this is no issue, I have no idea how to change this.

I installed version 0.8 of the tools under 2.54, apparently with the bundled 
version of python 3.1. After installing, attempting to enable the module 
resulted in the following error:

ImportError: No module named io_smd_tools-0.8

Occuring on line 1086 of space_userpref.py.

Bunging in a couple of print()s confirmed that the python path was correct. 
Renaming the module to what it used to be called - io_smd_tools - and 
reinstalling - allowed me to enable the module (I now have two entries in 
addons; one which produces the above error and the other which enables 
successfully.)

This is presumably an issue with the "." (or maybe the hyphen) in the module 
name causing __import__ to get unhappy.
I'm guessing this must work for someone else it would already have been found, 
though. My system is Windows 7, 64bit, and I've not tried it on others.

Cheers,
Chris.

EasyPickins here.
Attached are patched io_smd_tools.py and smd_test_suite.py.
(I didn't want to commit after being away from this project since November.)

The SMD importer didn't work for me. I removed the TidyArmature() call from 
readFrames() because TidyArmature() needs smd.m which hasn't been created yet 
-- readPolys() is called *after* readFrames().  I moved the TidyArmature() call 
into readSMD().

The SMD exporter didn't work for me with a Y-up SMD.  The indentation on 2 
lines in bakeObj() were (accidentally?) changed which broke exporting a Y-up 
SMD.  Armatures do not have a .transform() method.

What steps will reproduce the problem?
I have no idea. I was exporting a reference mesh only

And what I noticed was, upon a failed export Blender would create copies of the 
armature and the reference mesh labeling it with .002, .003, .004, ...

Converting Source bones to Blender bones (and vice versa) is proving very 
difficult. The major differences are:

  * Source bones are 1D points with rotation; Blender bones have a head and a tail
  * Source bones point down the Z axis; Blender bones point down the Y axis
  * Source is right-handed; Blender is left-handed

These create several problems:

  * The underlying complexity of turning a global vector into a local rotation. This has a solution that someone with enough understanding of 3D maths will hopefully find one day.
  * Import compatibility. For a model to remain compatible with existing animations it must retain the exact some bone rotation values. This prevents bones from being connected to their parents, as doing so nearly always affects rotation.
  * Axis difference. Either bones tails stick out at right angles (Z up) or we go with Blender and confuse anyone who tries hand-editing animations (Y up). The actual direction that bones face after export isn't a problem, thankfully.

My current theory on the process required for export is:

  # Convert bone vector to euler
  # Convert euler to matrix
  # Multiply euler by inverse parent matrix, write euler
  # Multiply matrix by parent's equivalents
  # Subtract parent head from bone head
  # Multiply location by inverse matrix, write location

And for import:

  # Convert euler to matrix
  # Convert location to matrix
  # Combine matrices
  # Head location = location * parent matrix
  # Tail rotation = location + ([0,0,1] * parent matrix)

[deleted issue]

Some think is broken, there isn´t .smd in import, only error in python console.

What steps will reproduce the problem?
1. Export multiple actions on one armature.
2. Save project.

What is the expected output? What do you see instead?
I expected it to just export and have no effect on the project

but it ended up removing data-blocks for my armature animations and when I re 
opened my project later all animation information was missing.


What version of the product are you using? On what operating system?
Blender SMD Tools 0.9.1 on blender 2.55 beta 64bit running on Windows 7 64bit

Please provide any additional information below.

Would it be possible, that the end frame is automatically changed according to 
the end of the active action?

That would be good for looping animation, when simply browsing through them 
quickly inside of Blender.

This is due to a Blender limitation, which has been refused as a bug. See 
<https://projects.blender.org/tracker/index.php?func=detail&aid=24460&group_id=9
&atid=498>.

While this issue exists the script cannot apply modifiers to shape keys. Users 
must create shapes only on meshes which don't have modifiers that affect the 
shape keyed area (e.g. Mirror).

Valve's new DMX format, a replacement for SMD, cannot currently be parsed. 
Adding support depends on Valve releasing source code.

-Selected Armature; Armature Tab, SMD Export Panel: Having the Action Selection 
set to "Current / NLA" (which is the default option) results in the action 
export disappearing in both the scenes and armature panel. Maybe this is 
wanted, however it is confusing.
 BUG WITH THIS: When "Current / NLA" is selected and then a mesh is selected a few buttons on the Scene Tab under Scene Configuration are missing such as the automated compile and the SMD information removal...
