Material Glow

[Chas / Aug Posekany]

Roy,

Would it be possible to move the selector for the material glow channel to the materials dialog box so we could set the material glow by material to different channels (more than one material glow channel)?

It's actually been requested from the SketchUp side as well.  I'm not a big fan of material glow so I may be pretty resistant to this.  What's your specific application?

[Chas / Aug Posekany]

I use material glow as opposed to making light fixture objects to try and simulate realistic signage applications in my commercial work.

The process Akinlolu has stated works but I cannot adjust the glow between different elements without going back to the materials pallette and adjusting the amount of glow for individual materials and run the rendering again. If I could assign a material glow material to select channels I could make these adjustments post render without running the rendering over and over to get the right effect.

Have you tried just tagging them as lights instead?

[Chas / Aug Posekany]

If I tag a line of 3d letters in a sign as lights I have to adjust each letter (light) individually based on overall size to get the lighting even from letter to letter. I don't have this issue if I use material glow.

[Roy Hirshkowitz]

This is a really interesting problem, actually-- I need to think about this a bit.  I'd much rather approach it from the lighting side, rather than the glow side.

What I do is, put all the materials with glow attributes on a channel and then adjust as need be. Also I enable autosave in Nxt format to I can play with the channels in the image editor as the rendering continues.
