Material creation help. A LED light

[neo187]

Hello all

I was wondering if anyone could give me some pointers, I'm pretty new to UDK. What I'd like to achieve is something like this on a light switch mesh:

So basically there would be an emissive centre where the light is and a less bright surrounding area... Any ideas on how i could achieve this? I am guessing that i could add two images, one for the bright centre and one for the plastic shell...but i am not quite sure how to do this...

thank you for your help!

You could use a red emissive texture on the material over just that center spot, then for the surrounding spot make a semi transparent mask to allow the emissive light to come through.

If I neded to be that close, I'd do some wicked bump-offest emissive thing with a projected 'bulb' being distorted by a height-map. If it were to only be viewed further, an emissive map is perfect. You could even simply play with a fresnel with your normal map piped into it masking out to give it some dynamics for that edge-case Medium View Distance (MVD) LED.
