MotorStorm [BCES00006] Some 2D Textures not transparent

[papahOOch]

The 2D textures for mud and fire are not transparent, and render as black chunks. It also on rare occations happen sporadically, but it's consistent when driving through mud and when the car explodes. The intensity seems to vary, But I'm suspecting it's because the problem is with the particle effects. It seems like instead of screening out the black parts of a 2D texture, it just renders the whole images. (Or something else, I'm not sure, that's just a guess.)

Screenshot of issue:

I have tried all four shader modes, antialiasing auto/disabled, strict rendering, all zcull accuracies, default settings, nothing seems to do anything with the issue. I noticed another thread mentioning this back in 2019 (source) , but I havent seen anything else about it, and most data from this game predates that. Other than this, the game runs very good, stable 30-ish fps on my surprisingly mediocre rig.

To reproduce, drive through mud, or blow up the car. The textures are flickering when they appear.

Specs: Windows 10 Pro 20H2 (Build no. 19042.1237) GeForce 1080 Ryzen 7 3700X @ 3.60 GHz 32GB DDR4 @ 1066MHz

RSX Captures (I took several, not sure which is the best):

RenderDoc: I have tried to get this glitch documented in RenderDoc, It just does not show up. I am 99.9% sure that the frames captured were the glitchy ones. Tossing it in, if it helps.

If there is anything else you need, let me know

Okay, so I tried the game with OpenGL renderer, and the problem does not persist. But openGL performance is less than half the FPS of Vulkan.

Is this a regression? I have never encountered this, and this title has been used for testing many many times. The log file is empty so I cannot see the configuration, I only remember this game needs WCB to render correctly if no patches are used (as it should be for testing)

[papahOOch]

Oh shit sorry about the empty log. It should be the most recent RPCS3. I'm gonna see if I can boot and reproduce it tomorrow, and give you an updated log.

@kd-11 Yes, it's a definite regression caused by some change in the past month or so.

I was able to get in game once today and grabbed this screen.

Unfortunately, after that I can no longer get past the title screen like another user just reported here: https://github.com/RPCS3/rpcs3/issues/8376#issuecomment-956500114

Always freezes here:

Here's the log for freeze: Freeze.gz

To sum up, here's the full list of issues:

1. Freeze in menus - new regression
2. Black dirt (this issue) - new regression
3. Car stutter - https://github.com/RPCS3/rpcs3/issues/8376
4. Misc gfx issues - https://github.com/RPCS3/rpcs3/issues/8373

[kd-11]

I am unable to reproduce this issue on AMD and NV GPUs (pascal). If possible capture a before and after renderdoc trace of the issue on pascal or rdna2.

Once we can figure out why it's freezing/crashing in the menus, I can grab that.

I've been testing the game for years on rpcs3 and have never encountered this. It's always at this exact spot (log above). I've tried various settings. This regression needs to be fixed or we need to find the new special settings it requires.

I can run the Game fine and got a Renderdoc Capture with my 1050 Ti https://drive.google.com/file/d/1zi04e2uOVZzVBGgxxk78dqA2uJ0a_Tsd/view?usp=sharing

Fixed the menu crash - due to unrelated data corruption regressions around Trophies and temp save data files.

Anyway, found that this commit broke the game - causing massive perf issues (fixed soon after) + black boxes as noted in this thread. https://github.com/RPCS3/rpcs3/pull/10900

[kd-11]

Test if https://github.com/RPCS3/rpcs3/pull/11204 fixes this one.

[legend800]

Yep, all fixed, thank you!

Not only did you fix the regression but the "purple dirt" is also fixed finally. Nice work!
