Steps to reproduce:
1) open users attached project
2) scene 'Torus'
- there are two models, one with triplanar node and another one without

Results: object with triplanar node is pixelatex
Expected: No pixelation

note: pixelation is not visible in 'Substance Designer'

This rendering mismatch happens because the Substance engine used in the Unity integration is the CPU engine, which only handles grayscale 16b textures and color 8b textures.

Workaround:
There is a workaround available: a new version of the triplanar filter, which uses three grayscale 16b textures instead of a single rgba 16b texture, is available here: https://share.allegorithmic.com/libraries/115
