I’m wanting to play with making some nebulas for a space scene and I’m wanting to use an emission shader hooked up to the volume of a mesh with a voronoi texture to give it a smokey look. The problem is I don’t like it when the voronoi texture gets cut off by the edge of the object, making the mesh shape visible.
Is there a way to use a gradient or something to make it fade to invisible as it approaches the edges of the mesh? I’ve been playing with the gradient and voronoi nodes all day and haven’t had any luck except to create a spherical gradient in the center of the mesh, and I’d prefer that the shape not be spherical. I’d like to have a linear gradient extending in from the faces just a little ways.
I’d appreciate any help anyone can give me.
