Created attachment 468465 [details] WGSL shader source Open https://spookyball.com/ and notice the MSL compilation error printed: program_source:377:28: error: use of undeclared identifier 'textureSampleCompareLevel' local8 = (local8 + textureSampleCompareLevel(global5, global6, clamp((local5 + (global8[local9] * local6)), local7.xy, local7.zw), (local4.z - 0.003))); it appears to come from this line in the attached wgsl shader: visibility = visibility + textureSampleCompareLevel( shadowTexture, shadowSampler, clamp(viewportPos + shadowSampleOffsets[i] * texelSize, clampRect.xy, clampRect.zw), shadowPos.z - 0.003);
