Title: Lightmix
Post by: RED LAB on 2017-06-28, 14:01:17
Hi everyone,
I might be blind but how do i use lightMix?
I activated it in the multi pass but there is only one visible.
So i activated Light select and dragged lights into it to check if it was the trick but nop....

The video tutorial should explain it, let me know if anything is unanswered after following that!


Thanks!

Understand, one light per light select.
Thank you very much

Just a question, If light mix is enabled, does it slowdown the rendering or it has no effect?

The first tests show that its way slower.

You can add multiple lights to one LightSelect - you group them by how much control you want over them. So for example if you have three spotlights in a room, and you want to adjust their intensity and color in LightMix all at the same time, you can add them all to the same LightSelect. If you want to adjust them individually, you'd add them to separate LightSelects.

LightMix shouldn't have a significant effect on render times, but it does affect memory requirements - and if that takes you over the limit of the memory your machine has available, then it will affect render time, but not because of the LightMix itself as such but because the machine has run out of memory. (This is another reason that may play a part in how you decide to add lights to the LightSelects, as each extra LightSelect will require additional memory, so you may decide to group some lights into the same LightSelect, to give up a bit of individual control but reduce memory requirements).

I hope this helps!

Yes that helps for sure.
Thank you for the clarification.
Great renderer and great team.
