Re: Volumetrics issues

In my opinion the problem is the lack of a feature: light sources currently have no "volume" property, so you can't tell them which volume they're in.

Re: Is Luxcore capable of rendering Fraunhofer diffraction?

LuxCore doesn't simulate light as waves, so it can't do any effects that depend on wave interactions. However, I'm not sure if the effect in your video is due to diffraction, it might be something else. For example, I've attached a file with an interesting shadow effect, might be a starting point fo...

Re: Haze

The problem with a foggy world volume is that it makes all light sources that are infinitely far away basically unusable. That means the sun, infinite lights like HDRI backgrounds, sky etc. If you want to have some light haze in the scene with a sun and sky overhead, you'll need to use a fog box mes...

Re: Haze

Yes. For example, you can surround the scene with a big box that has a null material with homogeneous interior volume. Use a very low scattering value, something like 0.001.
Remember to set the same volume as exterior volume of the camera, if the camera is inside the box.

Re: Texture Interpolation

In the latest daily builds, you can change the interpolation on image textures from "linear" to "nearest" for pixel art textures.

Re: Gradient (Blend) Texture

You can change the mapping type to UV or local.

Re: Two well known luxcore problems.

Those are SDS caustics (specular-diffuse-specular). LuxCore has three ways of dealing with this problem: The archglass (architectural glass) material can be used, with the downside that it doesn't have refractions, only reflections. So it's only suited for thin glass sheets where refraction wouldn't...

Re: Camera projection

Updating a scene is one solution, but i think having support for multiple camera at leat 2 camera is far more better solution, imagine that camera projection moving through the time, for each frame scene should be translate and again update after that to be able to render correctlly. Also having mu...

Re: Camera projection

Let say we have two cameras, Cam1 that should be used as a camera projection map as the first camera and Cam2 that I want to use as actual render view. That's no longer a camera projection though. It's more a rotated planar projection (if we assume Cam1 is an orthographic camera). By the way it's n...
