With GCC? no Still working on clang version. I'm getting farther by turning off LLVMgold plugin which appears to just be a link time optimization so I don't mind if that takes longer as long as it compiles and it can be determined if the problem is related to clang or a MacOS specific thing. I have ...

It happens every time with METROPOLIS for me, if I add additional checks for PDF being zero there to skip, it'll fail a few iterations later in the TraceLightPath IsAllValid assert with more Inf floats. If I run the RANDOM test instead it occasionally makes it past this point which is what leads me ...

Has LuxCore been compiled with clang on Linux before? I was hoping there was some GCC compiler flag handling floating point rounding but don’t see anything other than the windows fp-precise. Anyway thinking to rule out floating point accuracy/variability among compilers I’d compile on Linux with cla...

I was hoping to get Xcode debugger attached to the python tests but haven't had success with that yet. I can run the debugger with luxcoreui now, which I need to make a PR for some cmake additions to add macOS Debug symbols. Anyway I've attached the crash log from the OS which has the stack trace. I...

Continued progress on searching for root cause of the OpenCL with LuxCore2.1Benchmark on Nvidia cards narrowed down to the material Mix node being the culprit. If I delete the mix node from all materials and just route the previous color output to the input of diffuse color the program no longer res...

Doh... There is one, I'm just not reading today

Ah I see, so Use CPUs in Blender only works when a GPU Device is selected... I wonder if there should be a warning or Use CPUs becomes grayed out or something to indicate that from a usability perspective. Although I don't think the average user is doing this. :lol: Removing the devices select fixed...

Yeah something isn't working right, I'll keep digging. The film opencl being disabled seems to have changed the settings a bit and now it's failing on the Denoiser which is also trying to use the GPU instead of CPU. Weirdly if I try to deselect the GPU and leave CPU enabled in the LuxCore Device Set...

OpenCL mostly works but LuxCore2.1Benchmark.zip does throw an error `PathOCLBase kernel compilation error` The standard procedure to test if this is an OpenCL compiler bug or a bug in LuxCore code is to run on CPU OpenCL device only. However, in the Blender addon it is not possible anymore to selec...

FYI/Updates: I just uploaded a MacOS release of BlendLuxCore. Also been doing some various testing, looks like the ATI card I was using works find for LuxCore2.1Benchmark but the Nvidia GTX Card seems to be throwing a segfault so will need to dig into that. The Nvidia Card seems to work on other ren...
