Can the opencl compiling be remove in the current alpha of 2.4 ? it is annoying to that it tell you it will happen once and come again and again. at the ends you don't know what to believe

i mean that it really happen once ?

I will get there.

With the merging of the CUDA branch I imagine that we've to wait an update for BlendLuxCore to use it. Right?
At the moment, the last BlendLuxCore build has just removed the OpenCL support.

Also what are the final name to switch between opencl or CUDA ?

Not really, not only because CUDA is not enabled in current builds (see below) but because CUDA devices are listed together with OpenCL devices and they can be mixed and used as you like.

BlendLuxCore will have only to be careful to not use a NVIDIA GPU 2 times: one as OpenCL device and one as CUDA.

This was a mistake, I should have re-enabled the OpenCL support by default (while CUDA is still disabled because we don't know yet how to compile CUDA binaries on Azure).

There isn't really the need of a switch (see above how CUDA and OpenCL devices are listed). It is just strange to have something called PATHOCL able to use CUDA devices too so I would like to change the name for consistency.

In BlendLuxCore, we could simply have the label "OpenCL" replaced with "OpenCL/CUDA".

So we have to wait that all settle down between Luxcore and blendluxcore befor testing correctly

No, you only need a CUDA enabled pyluxcore.pyd and to select the devices to use for the rendering by hand in BlendLuxCore (or it will use 2 times the same GPU).

So finally is just install lastest build from luxcore and blendluxcore like before do the trick ?

Yes (when CUDA compilation is enabled on Azure).
