Hi
I am looking to achieve this effect.
Attached an image of the desired effect.
Any ideas?
Thank you
Phil
Have you checked [Volumetric Fog](https://forum.corona-renderer.com/ Volumetric Fog #msg144984)?
Thank you for the reply, but that dose not do it.
I have tried a number of options and the only one that works is , if you model the entire design and colour each bit of glass.
Otherwise, Glass altered and light behind it, but the fog Volumetrics don’t work.
Thank you anyway.

Here is my quick and dirty faked method.
- Create a target 3ds max standard directional light set shadows to caronaShadows, set it to rectangle shape and give it your stained glass texture in the projector map slot and aspect slot.
- create your stained glass window material with self illumination with your stained glass texture, change it’s object properties so it doesnt receive or cast shadows
- align your directional light so it is in the same position as your window.
- add volumetrics.
Also, you can make Volume box just where rays travel.
But note that caustic rays don’t show behind glass. Which is what you’re trying to achieve. (use thin glass or better, none at all, only textured spot/area light).

Thank you, I appreciate the time you spent on this.
I did this , previously, yes and its a very good cheat.
The reason I asked originaly was the client sited a stain glass effect from the glass, but ry are to boxes with light on the inside and the colour of the glass pumping out from them on the floor.
Like the attahed, it’s for an installation no natural light coming in.
But what you have suggested might do the trick locally to each side.
There is always a way round, and always many ways.
Thank you again.
Phil
