VRAY and floating walls

[Jblejer]

Hi,

 

I have looked a lot through forums on this topic and can never seem to get it right. I am using VRAY to render an interior of a house using only vray sun to show the client the lighting conditions. All materials are near white and transparent for glass. It is meant to be schematic and not necessarily realistic in terms of reflection etc. But, I get all kinds of light leaking everywhere. This makes it look like walls float and that the windows are leaking etc.

 

I have one rendering and the settings,

 

thanks a lot.

change the irradiance map preset from 'very low' to at least 'medium' and up the HSph. Subdivs to 50.

 

If that doesn't work tick the 'check sample visibility' checkbox

 

If that doesn't work either make sure your geometry overlaps a little bit where the floor meet the walls

 

If that still doesn't work then give up and open a beer

Hey thanks a lot for your post. It seems to have worked but the before and after times are 1:03 and 5:46. That is a significant increase. Is there a middle ground or some other area that I could cut the quality with out gaining back the light leaks?

 

Thanks again.

 

Justin.

quality vs. speed - that's the inevitable trade off. 5:46 doesn't seem that much to me though, or will this be animated at some point?

 

Try setting irradiance to 'custom' and -4 min rate and -2 or -1 max rate and see if that speeds things up, and/or raising the noise threshold in the vray: DMC sampler rollout to 0.02.
