Reply To: Why are two “Mapping Nodes” in Sequence needed for Volumetric Tunnel?
He most certainly will. I’ll be the first to admit I don’t understand the math enough to explain why this works, but here’s a GIF showing how stacking mapping nodes has a unique effect:
Note how the I change the first mapping node’s Y rotation to 45 degrees, yet the X-scale disregards the angle and stretches in “global” horizontal orientation. However when I adjust the X-scale of the second mapping node, it stretches in the 45 degree orientation. Similar to “local” space (I think).
