Test.3dm (376.1 KB) Sure. I’m attaching an example of what I am working through.
This is what I typically use - the render cache turned on - which makes rendering time doable. 16 seconds.
This one - the light is visible in bouncing back from the panel. 1 minutes to render.
Neon - I let this roll for 2 minutes. Grainy, but accurate.
I know the easy answer on this is go with the versions that don’t use the Render cache, but alot of times when the model becomes very large and I am on a tight timeline - render cache is the only way to go. Rather than 2-3 hours a rendering- it’s 15 minutes. But I always have to forfeit on indirect illumination. Making me Photoshop of lot of lighting in the end.
