Pixelated high contrast map lighting. about daemon HOT 11 OPEN

I still reproduce the bug on master.

I believe this is fixed?

I still reproduce it on Mesa radeonsi driver.

from daemon.

could you update the root post to make it explicit which hardware you use? This seems to be important for that bug.

[edit]
I added the GPU-Radeon tag

I've been on Nvidia when I reported the issue.

Interesting. I'd be surprised if only intel would not have it, so there must be something else causing the issue.

from daemon.

Oh, nevermind! This hasn't happened to me; I just moved the issue here!

from daemon.

We already have a GPU-AMD label so I replaced GPU-radeon with it (Radeon = AMD). I'm not sure this bug is Radeon-specific though.

To reproduce the bug, one should enable dynamic lighting (r_dynamicLight 1).

from daemon.

The test map is a map done by @FreeSlave, who is known to use J.A.C.K. editor, which only supports a map format upstream NetRadiant doesn't support yet.

It means the map was compiled with tools we don't use ourselves, like @FreeSlave's own branch there: https://github.com/FreeSlave/GtkRadiant/tree/map220_netradiant

So it's also possible the map compiler that was used had a bug and the produced BSP file is buggy, but I don't know how to verify it.

To my eyes this looks much more like an issue with our real time shadows though. Possibly a NaN/DBZ issue?

from daemon.

Our tiled renderer does not support real time shadows yet (and no one is working on them). So it's very unlikely a bug is in real time shadow: they're expected to not be rendered at all.

The forward renderer which had real time shadow code (feature I never seen working correctly anyway) is now deprecated and disabled by default. See also:
