UE 5.4 and UE5.3 import PY showing plane. material problem ? #45

Open b-summer opened 3 weeks ago

b-summer commented 3 weeks ago

I have install the last Xverse for UE5.3.2 and UE5.4. I using the demo_fox_ga.ply

FOR BOTH ue ENGINE, when I import the ply,the first time I could see the fox but when I've drop the blueprint in level, the render is showing only plane. Capture

even if I'm only using lumen, I've try to disable raytracing r.RayTracing.ForceAllRayTracingEffects 0 BUT CHANGING NOTHING

in material M_GS_unlit there is errors [SM6] /Engine/Generated/Material.ush:3461:30: warning: implicit truncation of vector type [-Wconversion] PixelMaterialInputs.Opacity = Local13; ^ [SM6] error: validation errors [SM6] zzz.dxil:4463:5: error: Opcode Discard not valid in shader model lib_6_6(closesthit). [SM6] note: at 'call void @dx.op.discard(i32 82, i1 true)' in block '#26' of function '?MaterialCHS@@YAXUFPackedMaterialClosestHitPayload@@UFRayTracingIntersectionAttributes@@@Z'. [SM6] Validation failed. [SM6] D3DCompileToDxil failed. Error code: Unspecified error (0x80004005).

when importing PLY the outpulog

v1.1.4 same here, show up for a second after dropping BP into the level and changes material to default also in output log:

got a solution that worked for me:

  1. r.RayTracing 0
  2. Disable Hardware raytracing in the Project Settings
b-summer commented 2 weeks ago

I've try turn off raytracine but have : Error: r.RayTracing is read only! I've turn off "use Hardware Ray T. when available" but nothing change. my solution for now is to use LumaAi plug, it's working fine for UE 5.3 I think with xverse the problem is coming from material. The one from LumaAi, has a different code

When i click "hidden in game" its showing colors and not gray planes. Any reason why? I also tried to diable Raytracing without any result
