I was making an icicle shader which use World Displacement like below, and planing to make a icicle blast effects from it later on.
However, I encountered two problems - the first one is that now the displacement is in world space and it will mess up when rotating the mesh. I tried to transform it into object space by using Transform Position node but it doesn’t support World Displacement. The second problem is that I need the mesh orientation from Niagara so that I can transform the displacement accordingly.
So my two question would be
- How do you transform displacement texture into object space?
- and how do you get Niagara’s mesh orientation in material editor?
I feel like there is an easier way. If you have any thoughts please let me know!
You can see the displacement starts broken when it the mesh rotates.
