i believe the answer to that might be 'none' - at least, none that i was aware of.

this is the same scene with the colour removed from the center lamp and it's Watts and Lumens values reduced almost to nothing.

isn't it a bit confusing that IOR increases reflectivity in a phong, and lower glossiness values give more glossy reflections?

In the video 22mb from the site, the demo guy is using an indigo plastic material which doesn't seem to be showing up in my version. Why might that be?

Can one simulate a matte/shadow material in indigo?
Or we need to actually make a real ground plane to sit things on as part of the 'world'?

I feel not ready for posting images yet ... lots of the images in the gallery are great. but they seem to have a lot of artefacts that show on surfaces like flecks of not quite resolved colour... like not enough samples. doesn't this create some shimmering in animated sequence? in the past i noticed...

Hi I noticed myself about 2 secs after posting that there's indigo materials. ok... but what if I have an older scene with many finely tuned raytrace settings that would take a long time to convert over (like local exludes, particular maps that modify the raytracing, and this sort of thing). It's a ...

Hello

I'm just learning indigo, very early yet.

I sent out from 3dsmax the cornell box scene, and that went fine.
The I applied a raytrace material to one of the boxes (mat01) and the indigo reports that it can't deal with mat01 material.

What's going on here?
