By the way, since ray epsilon is still a kernel parameter, I guess I have to pass the default min/max epsilon in BlendLuxCore to KernelCacheFill()?

Only if your default is different than LuxCore default one.

The binaries for all OS can be downloaded from here: https://dev.azure.com/LuxCoreRender/Lux ... dArtifacts (the down arrow on right)

You can replace your pyluxcore.pyd with the one inside the downloaded win64.zip (yes, it is tricky and suggested only for advanced user).

Thank you but I think that I'll wait for a daily BlendLuxCore build. Will it be available more or less soon or we'll have to wait the final 2.3 to switch the daily build to the 2.4?

We have to wait.

It would be good to have a LuxCore function that can tell me if a kernel recompilation is necessary, so I can show the UI message about it.

A callback during the rendering if a kernel is compiled or before starting the rendering ? (The later is not possible without having the scene).

Are you already intercepting the log output to show some message in Blender ? Could some specific log message do the trick ?

Can it be checked if I have a luxcore scene and renderconfig, but without a rendersession?

Code: Select all

renderconfig = pyluxcore.RenderConfig(config_props, luxcore_scene)

# Here I would need the check
...

# Locks up Blender, potentially compiles kernels
session = pyluxcore.RenderSession(renderconfig)

It could be RenderConfig methods

It will be a bit tricky because I compile many kernels but the only one that matter is the big RT/TILE/PATHOCL one. It could be something generic like RenderConfig::HasCachedKernels().

Yes, it should only check for kernels that take long to compile.
Otherwise the UI message can be misleading, because the render session creation also does other stuff that potentially takes a long time, like cache computation.

I have added a new LuxCore API RenderConfig::HasCachedKernels() method to check if a (long) kernel compilation time is required.
