Hello,
I'm encountering some issues with normals in conjunction with triplanar mapping. In CPU mode, it works mostly as expected, but there are some inconsistencies.
Here, normals are working ok in all axes.
But as soon as I plug a remap on texture_y of triplanar node the normal of that side gets inverted on the red channel (this doesn't happend on x and z textures of triplanar)
So to get the exact same result as before I have to invert the ramp of the red channel.
This leads to another problem, this time on GPU mode (RTX and CUDA).
Here the triplanar node seems to have the same problem as CPU but also when using the same texture on all axes of the triplanar
All of this suggests there is something wrong inside the triplanar node as this is not the first problem encountered using this node with GPU rendering.
I've attach the scene used for this example. Done in Houdini 20.0.688 and latest Vray nightly build.
