Re: Very long wait for caches enabled
You can try to raise the brute force radius scale, but this will lower rendering performance because the cache will be used less (over the whole image).
Or you could disable cache usage for the floor (in the material output node advanced settings).

Brilliant idea! Thanks.
Re: Very long wait for caches enabled
Do walls have thickness ?
Re: Very long wait for caches enabled
Likely, you can have light leaks due to numerical precision (or too large cache entry conditions like normal angle, etc.) in that case.
Re: Very long wait for caches enabled
Note that you don't have to add a solidify modifier to the walls if that generates too many new polies, you can also just put boxes behind the walls to block the light.
Re: Very long wait for caches enabled
After trying blocking volumes, thickening the floor, setting face smoothing to flat.. in the end what resolved it was changing the wall geometry so that part of it did not intersect with the floor geometry. Intresting to know. Will avoid this in future.
