Reflections, only in certain objects
I have a sphere that I'd like to be visible in reflections of certain objects, but not others.
How can I configure this? |
Make the none reflecting objects lamberts.

It is being used to light everything else, and reflections are displayed through them. I want to disable it for mirrors and reflective floors, so I can composite everything together in After Effects. |
You can turn off it's visiblity under the render attributes then I think that should do it.

Disabling the reflection option would also disable this for ALL objects though, and I only want to do this for my 'mirror' cube. I am looking for some kind of 'per object reflection relationship editor' |
Any idea anybody, or is this just not possible?
To clarify, my scene is like this: IBL Sphere Mirror Charecter And reflections WANT Charecter -> IBL Sphere DONT WANT Mirror -> IBL Sphere WANT Mirror -> Charecter -> IBL Sphere |
you might be able to do it with render layers, I'm just thinking how....
|
When you say IBL sphere, what ar you referring to? Did you put a shader on a sphere, or are you using true IBL in the render global settings? If it's just a textured sphere, then you should haev no problem doing this with render layers, and setting layer overrides for the reflections.

Theres still something I need to figure out though, and thats how to get a 'reflection mask'. I'll have a search in the forum archives, see if its been brought up before. And might I just say, Dann, you are god. EDIT: Cant find anything about render masks.. I just need to produce a black and white image that displays where a reflection is for use in compositing software. |
If you create a render layer with a useBackground shader as a material override, turn off shadowing on the shader and make sure that shader's reflections are on, it will render only the reflections with alpha channels. That might be what you're asking for, but I'm not sure.
FYI... flattery will you you everywhere |
So far so good, but I'm getting quite large soft areas around the edges of my cubes. Whats going on?

Regarding the passes, I got round this by rendering them using Maya Software, and seperate 'Directional lights'.
Much quicker and simpler. |
