tlehnhaeuser Posted July 23, 2010 Share Posted July 23, 2010 (edited) Does anyone know of a way to have a part emit light with it center the brightest and as it ventures towards its perimeter edges in all directions the emission is gradually reduce? Tying to render a neutron similar to the ones in this image Edited July 23, 2010 by tlehnhaeuser Quote Link to comment Share on other sites More sharing options...
Cary OConnor Posted July 23, 2010 Share Posted July 23, 2010 Well you can sort of achieve it. Enable emission on the smartpaint to have the part emit light. Use the Gradient Shader on the Emission tab. The trick will be to set the correct orientation. Screen XY might work or potentially the localUV.

Guest EricFoy Posted July 27, 2010 Share Posted July 27, 2010 I would try modelling the neuron as a semi-transparent shell shape with light source inside it. Stick a point light in the main body part to get it to glow more. I've gotten results before by putting point lights inside solid shapes too. Just make sure you select "Render both sides of surfaces". Quote Link to comment Share on other sites More sharing options...
Cary OConnor Posted July 27, 2010 Share Posted July 27, 2010 Eric's method is also better for performance. Cary Quote Link to comment Share on other sites More sharing options...

Cary 29389[/snapback] Yeah, I tend to avoid emission, because it seems to really hurt performance big-time. P.S: don't forget to make each neuron an assembly, and drag its light(s) into its assembly. This is a totally kool feature that enables you to drag the assembly around, and the light travels with it.
