Recently I had the chance to test the Gobos Lights asset pack.
An asset library for blender that comes with lots of custom lights with shadows. Some have animated shadows like the caustics one.
Link for the asset library:
Gobos Light Textures: https://blendermarket.com/products/gobos/?ref=101
The results were amazing! And it only took me about 1 minute to setup everything properly.
I made this video reviewing the asset library and this is results that I got.
(btw, feel free to subscribe to my channel. I just got 5k subs and would be amazing to continue to growing this channel and put more video on it soon )
Results (no post production):
Animated Caustics
Leaves Shadows
