Sonic Unleashed [BLUS30244] Incorrect Shadow Rendering

[ActualMandM]

Shadows in Sonic Unleashed seemed to be rendered weirdly, especially on the cloth shader.

RSX captures do seem to be a bit iffy with Sonic Unleashed, if needed I can try to provide RenderDoc captures. It's also worth mentioning that when upscaling the game, shadows have missing pixels in them.

Quick summary

Tails from sonic unleashed has weird shaded gloves. These weird shading issues also persist in in-engine cutscenes.

Unfortunately to replay a turing capture you need a turing card. I'll see if we can find something in the rsx capture though, could be some filtering issue or precision clamping in the fp16 code. Any AMD users with this issue should report it as well so we can get more data points. In the meantime I'd suggest first disabling native fp16 in the config.yml and see if it helps.

Still happens with Disable native float16 support set to true

Also happens with BLES00425.

Worth mentioning that this also occurs when the shader interpreter is forced on.

As far as I have tested, this issue is not affected by PPU/SPU decoders' settings, nor RSX multithreading, nor Shader Mode, nor Resolution or Renderer settings. The Read/Write Depth/Color Buffers options don't affect this issue either.

[ActualMandM]

Can confirm that #8367 fixes this issue.

I hate to be the one to point this out, but while this did fix the obvious shadow glitches like with Sonic's gloves, the baked shadows on the ground are still not accurate to hardware.
