best way to make emissive maps

Sharky85

im interested in how to make emission maps but ive never attempted them before and not really sure where to start. I was checking out this thread the other day (*http://www.polycount.com/forum/showthread.php?t=88996) and thought the effect looked really cool on the 'spider food' model.

Also, where do these maps go in regards to Max and UDK, im assuming in max it would go in the 'self-illumination' map slot?

You can also click on your texture sample and turn off color channels in the outputs.

Think about it like this. A world completely stripped of light. Everything is black.

Whatever you paint on the emissive texture is the only thing that you will see.
Basically emissive is like a mask. Black will not show up anytyhing birghter than black will.
