Re: Issues Building on MacOS Big Sur (11.4)

Does workgroup size need to be added to the compiler options hash? Also, if the device vendor changes the default workgroup size in a dirver update, do we need to catch this and force kernel recompilation? As far as I know it is not a kernel compiler option so it shouldn't be included in the hash. ...

Re: Issues Building on MacOS Big Sur (11.4)

In other words: in order for me to get kernel recompilation to work in 11.6, I must go into the kernel cache folder for the appropriate device (~/luxcorerener.org/ocl_kernel_cache/....) and do `rm *.ocl` It is sounds like the (driver) bug is related to returning (or reading back) the binaries of co...

Re: Black artifacts

It may be a driver version related problem. On Linux I have: +-----------------------------------------------------------------------------+ | NVIDIA-SMI 470.82.00 Driver Version: 470.82.00 CUDA Version: 11.4 | |-------------------------------+----------------------+----------------------+

Re: Black artifacts

I'm using Linux, I will try if there is something different with Windows. Do you get the same artifacts even if you render with only CPU ?

Re: How to solve Caustic Cache bright spot

BTW is there any case where enabling Light tracing could fail resolving the bright photton spot ? The reflection on the glass table of caustics on the wall (aka SDS paths) may still show some splotch. It is hard to say in your render because it is too small. If you have that kind of problem, enable...

Re: How to solve Caustic Cache bright spot

Light tracing should be always used to render normal caustics. Light tracing+Caustic cache should be used to render normal caustics+SDS paths.

Using Caustic cache to render both normal caustics and SDS paths requires often very high photon count and periodic cache update (i.e. long rendering times)

Re: memory cleanup

Doesn't C# have a garbage collector like Java ? Automatic garbage collectors are a nasty thing: you free an object but the actual real memory is freed by the garbage collector some time after (or may be is re-used for a new object of the same type, etc.). You have very little control on the amount o...

Re: How to solve Caustic Cache bright spot

Do you have light tracing (aka hybrid rendering) enabled ?
