Short description of error
When using some of my node groups from 2.79, some combinations will cause the material to display something similar to using a viewer node (from Node Wrangler) to view Texture Coordinates. My limited research has pointed me towards an OpenGL limitation of 16(?) textures; However, I'm not sure this is the case here.
The object on the left has my original node group(s) which has a total of 11 noise textures. The object on the right has the voronoi textures from "TEXTURE_ROUGHNESS" and "SHADER-DUST" muted but I added 5 more noise textures to the setup, bringing the total of the noise textures to 14.
The object on the right apparently works, but not the one on the left, despite it having less texture nodes.
Exact steps for others to reproduce the error
