getting great fast results using this option but have some negative values in some small areas in the render. Seemingly where I'm getting very little indirect contribution. Although it's present in the diffuse, It's mainly in reflect.

Also it's only in the diffuse and reflect for the gilight, not the other lights I have in the scene.

I can get rid of them by increasing the trace bias but get unwanted noise elsewhere.

As they are in the dark areas of the reflect aov I can fairly easily clamp them out in comp but it would be great to remove from the render.

Any ideas?

Thanks

Chris

Hey all,

Pushing interior rendering in houdini14/mantra to it's limits to make a choice against maya/vray for a heavy interior job.

With vray adaptive subdiv and light cache for indirect, render took around 16 minutes. (32gb RAM 24core)

With mantra the best I can get is 28minutes. (32gb RAM 24core)

I'd be interested if anyone felt that the speed of the attached scene could be improved without any increase in noise or loss of quality.

the hdr and render were linear exr's that i've converted to sRGB jpegs to add here.
