Are you by any chance tryin to emulate the cycles' trick to fake dispersion?

Unbiased Photon Gathering for Light Transport Simulation and anditional photon mapping related techniques

WooHoo! A new toy!

Ah, right, by default, direct light sampling is disabled if you use a mesh with more than 24 triangles. You can re-enable direct light sampling (but I'm not sure if the option is available in BlendLuxCore) or split the mesh in multiple objects to keep the total triangle count under 24. Mmm, I guess...

Sure:
Layers 1and2 = scene+1face plane
Layers 1and3 = scene+49faces plane

Hi guyz. The attached image is self-explainatory but I'll explain context anyway. I've got a simple scene, with an emissive meshlight plane. In the first case (left) the emissive plane is just 1 quad face, in the second is 49 quad faces. Both planes have same material properties. Is it normal this d...

No, aside from architectural glass material but it has a very specific purpose. In general, you are not going to find this kind of options in Lux because they are not physically based. Sometime you can use some trick like we were discussing before but, in general, they have always been out of the s...

Have you tried to use a 100% transparency value for the lamp or a NULL material :?: Premise: I'm using blender, I've forgot to mention it. Made a quick test, just out of curiosity. The only blender's native lamp which is affected by reflection is Area Lamp. I haven't found a way to set opacity in A...

I have no idea what a "loose geometry" is :?: Loose geometry or loose parts means deatached parts of the same object. For example a table model (single object) has knee, and legs meshes not connected each other. I guess he asks for a way to random assign of different input properties to e...

If you look at a similar IKEA photo you can notice that almost everything is very sharp and in focus. IKEA style is somewhat "cahotic" (not really but...) in terms of number of objects. They tend to put as many products as possible in one single shot and everyone of their products must be ...

Along with the already mentioned things (Denoiser, Light cache and Disney Shader on top of my preferences :!: ), I would suggest some things that I personally find extremely useful in cycles' materials editor: -Backfacing (from the cycles' geometry node), it's extremely useful as a factor to assign ...
