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 ...

Re: Glass with multiple materials assigned

Unfortunately no. I'm not sure if it is a connected issue, but I have noticed it as well.

Also, I don't get the image you posted in your blend file :?:

The correct image rendered through the camera should look like this:

Lens System Tutorial

I made a first tutorial on how to render a full lens system. This video shows how to read the values presented in a lens design file and set up the materials, plus two quick rendering examples. I plan to make additional videos with more complex lenses, or to talk about performance aspects. https://w...

Glass with multiple materials assigned

I am currently working on lens systems. One thing I wanted to do is assign slightly different glass materials to different faces - same volume/IOR but different reflection color - to test between which faces certain flares are formed. If I have only one material, I don't know if it came from the fro...

Re: Light Importance

But, in a scene with 3 lights sources, wouldn´t be easier to setup values like 1, 2 and 3? The light importance is not just a discrete sorting as with volume priorities. It basically tells you how often the respective light source is picked in the step where light sources are sampled. So if you set...

Re: Ultrabook for coding?

Based on my experience with small notebooks, I would look for a good keyboard! I have a small one from a different brand on which I can barely type correctly... On another laptop from the same brand its perfect though. So I would get my hadn on one to test if it works for you. Other than that, the 4...

Re: Metal Material

For metals, the IOR needs to be described as a complex number - composed of refractive index as the real part and the extinction coefficient as the imaginary part. Furthermore, these two vlaues vary much more over the visible range as in the case of glass, so approximating a single value would not b...
