LuxCore "v3.0" will require no compilation at runtime, not even the first time. If you provide pre-compiled kernels can't this lead to errors due to specific driver issues etc? I often think that octane has sometimes bugs with memory leaks and freezing due to pre-compiled kernels but I do...

LuxCore API already supports it (more or less): you see it in action when you enable viewport rendering and edit the scene. It is up to BlendLuxCore to redo the same when rendering multiple frames. It has been discussed in the past, it is doable but it is not a small amount of work. I see, maybe cu...

In other news about recent cycles development... persistent data! Luxcore has become crazy fast, however it all goes away if preloading scene each frame takes several times longer than rendering the frame... Being able to just selectively reload parts of scene would be an insane speedup for animatio...

It looks like you used very small backplate. Mine is much bigger than the whole scene (this is sometimes necessary for proper paralax camera movement and reflections, and of course if your scene is big) Yes you are right i made bckplate 10X bigger and it kill all. Another idea is just to compute ca...

how is this handled with environent/hdri light?

Here objectss.jpg iPhone model has 13 objects, some use multiple materials. It is in a clear case, now if I want to make phone into a holdout every material within every object has to be enabled and disabled manually. And even if the object had holdout flag I would have 13 of them to do manually. (b...

it would mean that both objects become holdout if I understand you right? Yes. If you use the object panel button (on the first of the hypothetical objects with the same material), the second is will flip too: you set all materials holdout connected to the first object, than refresh the panel butto...

I don't understand why you don't use transparent background and compose the image using alpha :?: It is a common way of doing thing without extra steps directly inside the 3D package. It easy efficient and fast. BTW i've tested it and don't have issue while disable PGI on the backplate and set back...

The far plane can have a large impact on the heuristic to determinate the radius used for PGI. You can set the radius by hand to try to work around the problem.

Yes I am actually using fixed radius, doesn't help. Maybe if I used some insane number of Photon Count...

To be more specific: I have a large Background plane that I want to appear as background (in render) not affecting anything but camera. I don't understand why you don't use transparent background and compose the image using alpha :?: Ok I see I have mentioned affecting camera only, but I want match...
