Currently the reason why the number of rays is fixed is also tied to some algorithm details - but i’ll definitely make it changeable in the future!

That would be great!!

The amount of video memory used is dependent on total number of tris and total number of lightmap texels (i.e. the square sum of lightmap resolution), so it is hard to estimate without seeing those data. However we may still have some hope - did you use the command line baking technique I’ve mentioned in the tips? It can usually save 1.5G~2G vmem since the editor is not rendering.

Thank you! I’ve seen the command line option, I will try it with the higher resolution lightmaps! …I’ll have to keep in mind this limitation… :S

For the splotches problem, it is very similar to the situation in vray where you have a low subdiv in Light Cache settings and have Retrace set to off. This problem will be fixed next time I change the algorithm.

Thank you! …to be honest I get a LOT better bakes with HIGH SPEED already and rarely run into errors! /testing as much as I can in my free time!

For the light leaking problem, Norman3D have already noticed it in some tests done with me. If you can also provide some simple scene reproducing the bug the it would be very helpful!

It wasn’t a leak it more looked like a surface was getting lighting information when it shouldn’t have (or the shape of the light/shadow)… I’m still not sure about that case but will make some changes and will let you know if…

I have re-baked an old, only HDRI test scene of mine to see the differences… WOW!!! So much more color and direction from HDRI! And ALL those “shadow bleeds” at contacting/touching surfaces are gone!!
