Reflections pass REDSHIFT
Hi all
I have an issue I hope you can resolve. I have a scene (attached) that I need to render out ONLY the reflection of the tube in the glass table. So not the glass table, just the reflections in the glass table. I have tried AOV, redshift tags, a bunch of tutorials and searching here for something I can use.
I think redshift sees the whole table as a reflection, and renders the whole thing. So I tried the tags, turning off visibility, but then of course there’s nothing to reflect into!
Maybe this can’t be done?

Hi James,
When the generator calculate the reflection values of the tube on the plan, it doesn’t mean it will only calculate the reflected area. Instead, the entire plan will be processed, the reflection values calculated, and then the values in the non-reflective areas will be zero, as you pointed out in the last of your post. However, I think I had come across a method for doing this using the Boil tool, but I haven’t been able to replicate it yet. If it’s related to a static shot, you can remove the non-reflective plan parts using the Boil tool or cut them with the knife tool, but if you need to move the camera so you will need another solution like I stated earlier. I’m waiting for you to let me know which is the case with your scene. I hope this will be helpful.

Hi Kouraib, thanks for replying. OK that makes sense, and the scene is a moving animation (the one I am actually using will be composited onto a mirrored table) so I need to find a way of capturing just the reflection. Thanks

You’re very welcome, James! If you simply want to make the object invisible while still leaving its reflection on the glass plane, you could do so using the composite tag as shown in the screen recording below. I hope this will be helpful.
