Projection issue for Tile Sampler Mask input (Triplanar for Tiles/ UV for Mask)

Hi!

I was wondering if anyone has ever created a texture generator for substance painter that uses the Tile Sampler as a base. The problem I'm running into when I use my generator in painter is that I want to use a painted input mask in the tile sampler but use triplanar projection for the tiling. I'm working with a model that has different texel densities across multiple UV shells so it would be best to use Triplanar projection in that case.  But when I do that, my mask input also gets projected in Triplanar which messes my mask all up. Is there a way to make the tiles in the tile sampler use triplanar projection when taking a UV projected mask?  I really like that the mask input for the tile sampler cleanly takes individual tiles out.

Thank you!
