Very simple Material question re R16vR19

I think you're wrong about that. If a material is 100% transparent, luminance will not work, and it wouldn't work in R16 either. In fact it doesn't, I have just tested it in both ! All I can think of is that in R16 your transparency MUST have been less than 100%. And indeed that is the way we can do self-illuminating liquids, just drop transparency brightness to around 60%.

Nigel does pop in from time to time, but he has moved on to MODO so doesn't run the cafe anymore.

There's no need to delete this, as it is a question new people encounter often, so could have helped someone else. But as you have removed the content, this can go now, and you have the power to do it ! Just delete your first post !

    Yes I got that while trying to make the comparisons. I was sure I used to make self-illuminating materials that way before. but clearly, I did not :/

  • I probably should have added ion this discussion that I have made a glass material before that when global illumination was switched on for rendering would self-illuminate. but I can't remember how I used to do that. It's likely that I used a glass preset from the library and then added a luminance channel. I think there were some glass presets that were transparent in some other method from the regular transparency channel. perhaps it was this that allowed a self-illuminating glass. Or maybe I dreamed it and just think its part of reality. lol. I actually do that sometimes. lol.
