Ok this will probably be a basic question for most of you.
how do i make something glow in unreal?
i think its an emissive texture?
how do i make one in photoshop to add to my texture?
say for example a red or green light on a door to make it look like its open or closed? or an exit light on top of a door?
thanks for any help that can be given
To make things glow in UDK just add a texture that has colour where you want the glow to be and plug it into the emissive slot (the texture should be 100% black where you do not want any glow) and multiply it with a constant.
You can make the glow bloom by pushing the constant value past 1.0
Hope that helps 
thanks guys, this help big time,
im slowly getting there,
im just finishing off a church ive been working, so ill probably have some questions on udk for that too,
cheers, andy
No problem
Thanks for this,this helped me a lot
Hello, for the constant i see there are several diffent ones, does it matter what one is used or can any of them work? Sorry for the stupid question but i only been at this a short time and still trying to take it all in.

You probably want to use a Constant 1 Vector.
Thank you for the reply. Since i'm here i have another question. How can i get multipe objects to glow different colors on the same image? A control panel for example, several sets of lit buttons glowing in different colors. Thanks
If the share the same UV's, then it is just a case of painting different colours on the emissive, map.
If they are totally separate objects, then you would need to make separate materials for each of them.
unwrap the model. find the face that's going to glow, paint it in the color you want and everything else black.
