Reply to How to use KTX file Image3D in ShaderGraph?
Also tried create 3D texture from PNG images and set parameter on ShaderGraphMaterial. But still not work. Image3D/Image3DPixel output always white, Image3DRead output always black. var images: [CGImage] = [] for i in 0..<32 { let image = UIImage(named: "\(i).png")!.cgImage! images.append(image) } let tex = try! await TextureResource.texture3D(slices: images, options: TextureResource.CreateOptions(semantic: .color)) let entity = scene.findEntity(named: "Slice")! var material = entity.components[ModelComponent.self]!.materials.first as! ShaderGraphMaterial try! material.setParameter(name: "Volume", value: .textureResource(tex)) So, likely the problem does not come from the KTX file, but Realitykit does not support Image3D yet?
