PBR Materials and Vulkan crash - GZDOom

[DrR0Ck]

Hello folks!

I am trying to get a PBR materials mod to work with Vulkan rendering on recent builds/versions of GZDoom. I get the following error as soon as I start a game:

Execution could not continue.
Could not create graphics pipeline: ó

Code: C0000005 (Access Violation - tried to write address 00007FFAFBC8D9F0)
Address: 00007FFAFBC8D9F0
Flags: 00000000

I have no problem running the mod with the GL renderer, but on my AMD GPU, I get much better performance using Vulkan. As an additional bit of information, I can run the mod with Vulkan in GZDoom versions up to 4.3.3, but later versions/dev builds all crash immediately upon starting a game (new game, load, etc. - I am able to load the game to the main menu just fine). I would also note that I run current GZDoom versions without issue without this particular mod.

The PBR Materials I'm trying to run were ripped from the DR4 (Doom Remake 4) mod that can be found here: https://www.moddb.com/mods/doom-remake-4

Let me know if there is any other information I can provide to help troubleshoot. Thanks very much!

Edit - I attached the crash report if it helps. Thanks again!

Thanks for your response! Any suggestions as to where to ask? I don't use discord much.

So for what it's worth, I tried the latest gzDoom git build - 4.6-pre67 and I am now able to run the PBR materials without crashing. So whatever was going on has been corrected.
