torus blast wave – texture problem

[Graham Quince]

Hi everyone

I’ve been trying to create one of those planetary blastwaves you see in almost every sci-fi movie.

I’ve got a torus shaped quite nicely into a energy wave, but I’ve had a lot of problems trying to texture the leading edge to fade so that the inner side is transparent.

Does anyone have any suggestions?

Try using a circular gradient in the alpha channel.
