Quote - A few tips on getting loads of characters in a scene...

Textures, textures and textures. Reducing geometry will not have as big an effect as reducing unsuitable texture sizes.

You do not need 2000x2000 pixel images for diffuse, bunp and spec for eyes on a secondary character. Same for face, torso and limb textures.

You can collect textures and then reduce them manually using a graphics app, I recommend IrfanView for the PC. If possible, reuse textures but change diffuse values for variety in background characters.

It is possible to export characters and scenery separately from Daz Studio and combine them for Lux rendering. Makes editing materials much easier.

Getting them into Lux has never been a problem, its having them all on-screen at the same time, at least for me. I will certainly try, maybe even right now, how many incarnations of just bare genesis figures I can get before things slow to molasses speeds. It's the strangest thing though: just with Studio, I can have literally a whole world of props on screen, but figures kill response time (again, any more than 4 on my rig). And I never run out of RAM or even get close in these instances, its just Studio bogging down with what I presume is too high a vertice count according to the scene info tab. That's why I figured this deal was geometry or mesh related.
