colored glass reflections on walls

[mugea]

Hi people!

I recently started using Corona and I cannot figure out how to reflect the colored glass objects on the walls. Here is the scene I am working on. The objects are colored glass but I cannot see their colored reflections on the walls. I can see the reflections in the material slot samples but not on the scene. I used the clear glass corona material and changed the refraction colors to red, yellow, green etc. and matched also the reflection colors. Reflection level is 1.
Is this a material issue or a render setup issue? I need sharp (but realistic as possible of course) colored reflections on the walls.
Bonus question: When changing the refraction color, the colored glass loses the authenticity and creates noise. Please see the image. And I do not get why the colored glass in corona material library did not work at all.
Thanks in advance for the answers!

I did a scene a year or two ago where I colored an entire hallway with just the tint of the glass. If you'd like I could look for the files and share a mat graph with you.

On your reference there is no reflections, you showing shadows, for reflection bounce you should enable caustic. And your scene setup have no light on glass so you can't see color shadows because it's already whole room in shadow from walls

@cjwidd - Thank you, it would be great if you can share with me. Your scene looks amazing!

@sprayer - I will check caustics topic on the forum, thank you. But I am not sure if I understood your comment fully. The sunlight should normally give the colored shadows, right? Also, there are other interior lights in the scene.

What I am trying to do is to experiment with light and reflections on the walls in the most realistic way for some art projects. Do you think there are better options for this other than 3dMax+Corona?

As already said, you need to make sure that the sunlight or any other artifical lights are pointing directly to the objects that has to reflect colored light. And of course enable caustics in the performance tab.
