View Full Version : Roughness similair to reflection blurring on Conductor node?

I have an interior that I am working on and have been rendering it in FPrime up until now. I tried it with the Lightwave native renderer and my scene brings Lightwave to it's knees about 5 seconds into rendering. I have been using nodes more and have lots of Conductor materials set up for surfaces in my scene. I took any reflection blurr to 0% but still had the same problem until I disabled any nodal surfaces I had then it rendered just fine. Is the roughness setting in Conductor similair to reflection blurring?

yes...

That definitely explains the insane slowdown on renders then. Time to go through all my objects and crank the roughness down. :thumbsdow I really hope Lightwave is able to handle reflection blurr better sometime soon.

Untick the "blurred reflections" checkbox on the advanced tab of the Conductor.

Thanks for the tip.

Lowering your number of rays and using non-nodal textures will also speed up your render. Not only are nodes in general slower to render but the material nodes specifically are designed to simulate real-world materials and as such take longer to process. Non-nodal surfaces still can have reflection blurring, and it should render faster. Look on the Environment tab of the Surface panel. Lower samples will produce a rougher reflection and using a reflection map will allow you to reduce your rays even further.
