Matt-Liell Posted August 7, 2003 Share Posted August 7, 2003 I want to make parts of my model light up or "glow" if you will. Now I know this is done with shaders but I'm not quite clear on how. Link to comment Share on other sites More sharing options...
Fracman Posted August 7, 2003 Share Posted August 7, 2003 Basically you have to draw two textures, one with the normal skin of the model, and the glow texture. For that you start with a black background and add parts that should glow there (use also some blur). Then you have to create (or copy) a shader that uses the blend function "add" (GL_ONE GL_ONE) on the glow texture. You may look at the models.shader for some examples, but nearly every shader in JO has some glowing Link to comment Share on other sites More sharing options...
