Hey all, I have been playing around with modelling in blender and would appreciate some help on getting a face to emit light.

The model is just a simple computer screen, and of course the screen needs to emit light. However after much research and reading various stuff on google, I am still not sure how to go about this seemingly simple task. (probably me that is simple lol)

I understand the Cycles rendered in blender can be used, but I believe it doesn't support smoothing yet, and since the model has some smoothing applied I would need to use the Blender Renderer - well I think anyway.

Can anyone point me to a decent tut on this?

Thanks for any help.

You can create an illumination texture and the put the entity shader in game to highest.

Copy the texture, edit it and make the areas you don't want to glow black/very dark grey and the areas you do want to glow white/light grey (grey is to adjust the level of brightness)
Then save it the same as the normal texture but _i.DDS

You can adjust the colour it glows by changing one of the other textures but I forget which one.

Totally agree with smallg here.

You can create surfaces that emit in blender, but getting them out of blender is a bit of a chore if you're using cycles.

The easiest way is as smallg said to create a copy of your diffuse (_D.dds) texture, paint the parts you want to emit in white, then all the rest in black, then export it as _I.dds. It's basically a mask texture that tells the engine to remove bloom from everything in black, and increase bloom on everything in white, with shades of grey varying values in between.

Lol, I spent the best part of a day trying to research this, and you're suggestions are just the ticket. I tend to try my best to work out how to do stuff before asking for help, but sometimes it would be better to ask first! lol.

Many thanks smallg and Belidos, got the effect I was after with you're valued help. I know it has been said before but this is one really helpful forum - like REALLY helpful!
