I’m getting some pixels that are returned -1.#IND0 in the voxel render when using Phong. The larger the voxel size or filter size, the more pixels are affected. Alpha is fine, only the color seems to be affected.
Moving the light, or changing the clipping on the object seems to affect it, but moving the camera does not, so it may be something related to the shadows, not the highlights.
I don’t have a scene to send because clipping the PRT down to something manageable makes the issue go away.
