Welcome to the new update of the Glass Caustics and Dispersion Shader! It’s been a bit past a year since I shared the original nodes, and I have been wanting to fix them for a while.
The shader is not at the speed I would like it to render, but I am very happy with the look of the fake caustics. I will certainly be looking to optimize the nodes, and I already have a few ideas of how to tackle the problem. The caustics may, once again, change visually, but I want to prioritize speed.
Only the “Glass Caustics and Dispersion” node group is under a CC BY 3.0 license, but its output can be used for any purpose.
Here is a folder containing the .blend file, documentation, and images from the documentation: Folder v2.0
Finally, here’s a preview of what it looks like:
Hope you enjoy, and if you have any concerns or ideas, please tell me!
