It is but it is a parameter BlendLuxCore doesn't expose (the number of samples it will take the transition from block to pixel rendering).

I mean Dade even if option B is adding less pressure after first samples compared to A. The fluidity during first sample in option B is simply from another level and this almost no matter how high you set block size in option A. So for me there is a weird thing we can improve here. You are renderin...

By default, the object ID is random, you can overwrite it to have a fixed value.

This would be great. You might also consider adding this to triplanar mapping as well where randomization makes a lot of sense. In those wooden pieces I actually used triplanar mapping. All the sides are randomly rotated and shifted to get the variation which simulated the randomness of production....

The settings should be correlated with the view port size. You can not have a single setting responsive for any view port size.

On nvidia‘s graphic transfer rate from RAM to VRAM is 14 GB/s. This is 32 times less than VRAM to GPU cache. The slide is about CPU/SSD/etc. (any device attached to the PCIe bus) to GPU ram transfer rate. It can have a huge impact on some application. In our case, it could highly increase the speed...

Emmm, in addition, is the wo and wi to determine whether to reflect or transmit in evaluate funtion? Glass is a specular material (i.e. a delta one) so GlassMaterial::Evaluate() always return "Black": https://github.com/LuxCoreRender/LuxCore/blob/2863718772213dd938913da4fff37b0c0ffaf49f/s...

It works also if it inside and you assign the volume to the camera.

You didn't packed any of the required images in your .blend file (you have many .png and a HDR referenced by the file):


I assume the .bcf file is so large because it includes them while your .blend file doesn't.

Can you use just the default scene ? Is your default scene broken ?

I want to implement a standard surface material similar to arnold, like https://autodesk.github.io/standard-surface/ However, when luxcore performs evaluation, only one of the reflection and transmission can be calculated at a time. How can I implement multiple lobes like a standard surface? Just c...
