I was playing with this a while back - trying to come up with the ghostly blue glow from an Ion engine.
- First, load a cone shape in blender. Under "materials" set its diffuse color to solid black (0therwise this won't work).
- subdivide the heck out of the cone!!! The more subdivisions, the better!
- save the cone with a .obj extension, then import into terragen.
- under the 'surface shader' tab for the cone object, click on the green plus sign to open the 'go to parts shader' dialog
-in the parts shader dialog select 'edit internal network'.
- Now insert the .TGC file included here.
- Break the connection between the red material shader and the gray material box
- connect the output of the .tgc file to the gray material box
- now add a light source, color it blue and position inside the cone, toward the large end.
Render the image. With a little luck you'll see a blue, semi-transparent flame like in the picture I've attached. You may need to play with the color and intensity settings. The ion glow is too sharp, so at this point I load the rendered image in Paint Shop and guassian blur the entire blue cone and the effect is what is seen in the 2nd picture. It's not perfect, but it met my needs. BTW, I "think" the .tgc file comes from Dandelo. Not certain though.
