View Full Version : Light emitting/glowing textures?

I am trying trying to create a texture that emits light. Like creating a fluro light tube were the texture is a light source.
I looked at the glow effect but I noticed that it doesnt actually produce light itself (since its post-) and needs light to be cast on it to see the glow.

Any clues as to how I would go about this? I guess its much like an led light but i need it to cast light normally.

Any help would be appreciated :)

turn up the incandescence of your material and render it with mental ray - final gathering on ... that should do it

Alot of my lighting goes slightly whack if I use mental ray now, not to mention the render times I can do without.

Any other way?

Sorry, I believe mental ray is the only way to do that at this time. Unless of course you know some major c++.

If you know mel you could walk your surface in uv( using point on surface ) and evaluate the texture with colorAtPoint, creating point lights where the texture is brighter than a threshold and setting the light color to the texture color.

Are you using a surface shader? turn the colour value above 1 to play with intensity, and the glow obviously does just that, turn on FG and whamo you have a light emitting object.

Don't make it harder then it needs to be just fake it with a glow and a regular type of light..

If you do it well enough no one will be able to tell the difference..
