Hello,
I have an issue with rendering 3d scans for Android VR (32k triangles)
I have different objects: a giraffe, a dino. Some objects always render conrrectly, some, tend to have black triangles moving on the surface when I approach the camera.
Different builds of the same scene sometimes (rarely) don’t have the bug.
I’m using mobile HDR.
- some shaders (giraffe) work on every objects
- some shaders (hammer 2) fail on every scan objects, but worked on a simple SM sphere.
- some shaders fail only sometimes (dino)
- some objects, fail with new shader, but not with some other (hammer works with Giraffe.
- within the shader, just using the BC map reproduces the problem.
- giraffe and hammer shaders are instances of the same material
- copy of giraffe simple also fails
- having 2 objects with same shader in the scene fixes the problem (added a dino static mesh close to camera)
- isse is distance related: closer gets darker.
- Some objects (lady) don’t show black, but a colofrul layer that looks like a mixture of UV gradient and ORM pass.
- Dino seems to have problem after going through the LODs
I am a bit at my wit’s end on this. If anyone has experienced this, I’d be grateful to hear about your hindsight. I have not built for non VR android before, so I am not sure if it is linked to VR or android port.
