Re: Custom Normals do not work in render

how did you assign the custom normals? I am currently working with them for my lens addon. I have noticed that in Blender, when you create an object such as a cylinder (with 90 degree corners), select an edge and ecxecute "split normals", it will not produce the correct split normal directions. For ...

Re: Setup of a special material and emission situation

I don't think it is possible now. In RGB space, the yellow light must be composed of similar parts R and G, while a red-looking filter must filter out almost all G... hence ending up with a red light after transmission. There was a nice example on discord recently where someone passed the dispered s...

Re: Caustics Corridor

very cool. And the pebbles on the floor add a certain "randomness of reality" to it :)

Re: Glass with multiple materials assigned

ok yes that could be the explanation for issue 1) from my previous post. I'm wondering ifwaht Dade siad there has something to do with issue 2)... Though it doesn't concern the camera here (there are no rays going directly from the camera to any of the lenses), and I also don't see any volume compar...

Re: Glass with multiple materials assigned

I didn't follow this up a lot until just now, and I can say a few things: 1) The original issue with only a different material , but both having the same volume assigned is suddenly gone in new daily builds, and it is also not present in v2.4. Not sure what of course but must have been in some inter...

Re: Darkness in transparent surface ?

Might be a bit extreme just to get that surface clean. But worked. It's not really extreme when you consider the geometry. Since the term hasn't been written yet: it is the consequence of total internal reflection (TIR), i.e. light bouncing between the surfaces. You can actually quite easily calcul...

Re: TwoSided material

Does the object have a negative scale in Y direction?
Normals won't show flipped in edit mode unless you apply the scale.

Re: Glass with multiple materials assigned

CodeHD, you should improve the code of your add-on. :arrow: See how lens meshes are made fit for Modifier Subdivision. I don't want to go into detail here, as it would be off-topic. I might add some more in the addon-thread lat some later time, after I tried some things. In short: You can have too ...

Re: Are these shadows working properly?

Yes, that is possible. Depending on the ratio of distances light to table and table to shadow, as well as the size of the light you can get this effect. Effectively, the shadows are so wide/soft that the region of full illumination becomes smaller. The following drawing illustrates this. Sorry that ...
