Re: Different HDRi for Lightning and Camera?

I found a workaround not the best or efficient but it gets the job done. Would be great to share so others can learn about it. ;) Textured Dome mesh. :idea: But that doesn't have the right "light intensity". From what I gathered you can't have emission w/o influencing other geo. As mentioned before...

Hey,
Is it possible in LuxCore to use 1 HDRI for rhe lightning and annother one for the viewport/camera?
In Cycles i can use the Lightpath-Node for that, but i read that this node will not come for LuxCore.
Nope, it isn't possible.

Re: Histogram-preserving Blending for Randomized Texture Tiling (aka Procedural stochastic texturing)

Good looking and a necessary addition. 8-)

BTW
Are there any plans for custom controls like U&V offset, rotation & scale, amount and type of blending?
Here's corona's version for example

Re: Article about free renderers, featuring LuxCoreRender

Yes, Blendigo is Blender exporter for Indigo which is "free to use" with a resolution limit 1M pixels per render. About Corona, it's v3 that is still freely available for commercial use. I admit these are shortcomings*, but are feature-full and not preventing any kind of free use. *For ingenious, in...

Re: Article about free renderers, featuring LuxCoreRender

+ A couple are still out there for free - one is Corona for 2.79 (development slowed down to a halt w/ 2.8+ mostly 'cuz the bridge is a volunteer work of a single developer and a new standalone version is being worked on) and other, if 1MBpix size limit doesn't bother you, for GPU/CPU spectral, pred...

Re: Displacement problem

Set Object to Shade Smooth. "Flat" breaks rendertime displacement - common to raytracers.

Re: Underwater caustics

Basically, you get finer Scattering Scale control with Scattering (color) = Value 0.01
Scale is then set to 50 & with a few other changes to amplify, exaggerate the volume caustics alike...

Re: question about anisotropy

I agree, anisotropic rotation has been left out or aside for too long. Too tedious, time consuming to do it the old way.
And images - comparisons of results & references would do great along your description ;)

Re: Camera non uniform bokeh support

I added the support for custom bokeh to GPU code. Thank you. About bokeh chromatic aberration: current internal camera interface only returns a ray (not a color) so it is not possible to have chromatic aberration inside the boundary of the current interface. Indeed, the interface can be extend, but...

Re: Camera non uniform bokeh support

Will there be RGB tex support or BW/grayscale only? It is a weight so it is gray scale only. Note: RGB support also allows creation of chromatic aberration for that extra realistic touch. And becomes especially valuable when you know about Out-of-focus point spread functions (paper) ;) The paper se...
