I am just thinking how such a thing like a laser sword could be done in bleder. Specifically I am talking about an effect kinda like ‘Outer Glow’ in PSD where you have f.e. a white core with a bluish glow around it (that fades into the background colour).
I tried to reproduce it in blender and I came to a point where it’s been ok, but not really good. .blend is attached. test.blend (554 KB)
Basic node-setup: Basically gradients are used for color and emission to define the volume. But I am not able to apply some alpha effects to the volume. Can anyone give me a hint on that one? Thank you very much!
