Hi there! I just tested the stage light effect that we will roll out in the next version. 
About this new stage light, we optimized the fog effect and support Gobo(custom patterns).
More features to come! Please stay tuned.
Important:
We’d like to preset a few patterns to switch. Do you guys have any images or ideas to share?
For example, a D5 Render logo in color
Maybe you can insert something to simulate caustics there?
I think it is hard to simulate caustics using stage lights 
Projector lights are a great way to simulate caustics. They are the only way I have ever seen used effective as a workaround. Obviously the light would have to support animated textures.
I’m a designer, my job is to design clubs, I want to be able to use MA2 for control, similar to UE5 and depence 2, this is the product I use D5 pro to render, it works I spend too much time, my creative efficiency is low, is there any way I can install additional plusins from outside for D5???
