Re: It is Not the Glass Container, it is the Glass Itself

It is Not the Glass Container, it is the Glass Itself :!: You need to have half of the juice directly visible to notice the difference (like in the original test scene). In your test, all the juice is under glass shadow. I think I see what you mean. I can arrange the cubes in a way they do not get ...

It is Not the Glass Container, it is the Glass Itself

It is Not the Glass Container, it is the Glass Itself :!: This means intensity of volume scattering is limited by material glass properties to approximately the same energy level glass transmission is. What is okay for transmission is wrong for scattering because scattering might be as bright as if ...

Scattering Volumes, openCL hybrid with pgic indirect cache

In contrast to BiDir, see Hetero- vs. Homogeneous Volume , openCL hybrid with pgic indirect cache is capable of rendering brightness gradient in scattering homogeneous volume. Probably this is because of pgic since without indirect cache gradient is not rendered. Size of look up radius is good betwe...

Hetero- vs. Homogeneous Volume

On the wiki pages examples named for homogeneous volumes are milk and orange juice. However, BiDir is not capable of rendering brightness gradients with homogeneous volumes. The result will be a homogeneously shaded volume. Name is concept. To get a bright surface and a darker volume bottom as expec...

Re: Computer for Luxcorerender

Hi, FarbigeWelt! I understand why you got another picture - you used version 2.8 of Blander. So the same scene at 2.79 and 2.8 looks different. It means that the old projects will look different at 2.8! I wonder if rendering time also differs. And the modifier "Weighted Normal" in 2.8 works for Lux...

BiDir Today. In the large shadow of Hybrid Path with PGIC

A few weeks ago, Dade introduced the new option for the CPU and openCL path render, so called hybrid or back-, forward or light tracking. Since this introduction BiDir path (Bi-Directional / eye and light path) lost most of common interest. The new option is much faster than BiDir with same or even ...

FarbigeWelt, did you change the scene?
Why did you have another image?
Hi Dez!
I have only changed Blender windows to show more relevant data.
Neither did I zoom nor rotate nor anything else in the viewport.
