Knack on shadPS4 discussion and bugs - Randomuser8219 (Knack) - 06-05-2025

Here you can discuss about Knack on shadPS4. There's also a hefty bug list as you can see below.
Current issues in 1.00:

PM4 type 0 race condition. The 3 only ways to fix it depending on your hardware is to enable Async, Debug log filter, or rebooting your PC.
Device lost on NVIDIA, caused by compute shader 0x9521885c30e19f67. Link to the shader's IR, SRT, ASL and SPV. FIXED!
Broken UI text that appears garbled.
Color issues in many places, like 1-1, Knack's central relic, and laser robots. Likely caused by an API format issue. Fixed in 0.10.1 WIP by IndecisiveTurtle's random fixes
No shadow casting, the game is outputting the shadow map in a different way shadPS4 doesn't like, causing it to not appear. Discovered by Niko on the Discord development channel. UPDATE: Shadow casting partially works, only in certain parts of indoor areas. UPDATE 2 - Outdoor shadow casting works!
Broken effects, like smoke and super moves.
Device lost on AMD at chapter 1-2.

This game has heavy use of MRTz depth exports, which we don't support yet.
Horizontal banding on NVIDIA.
Ambient occlusion doesn't seem to be present.

This is just a more-in-depth one with some that I missed.
