Hi,
Sorry but I can't figure this one out and its driving me a little nuts!
I have a scene where I need to replace an objects shader (configurator) numerous times. Now the objects in question obviously reflect in other elements in within the scene and I want to be able to capture those reflections within the object render selection.
So as an example.
I have white room with mild reflective properties, enough to see a faint reflection of the orange ball that sits in the middle of the scene. I now want to make that orange ball black with blue stripes, I apply the new shader and want to render the ball. However the reflection within the roomset is still of the orange ball, so without needing to render the whole scene, I just select the ball and hit render. This then includes the reflections cast on the rest of the room, so in photoshop I can just drop the new layer in which is of the ball and its captured reflections and overlay it.
I'm trying to get away from relying on FStorm (having to work with some other visualisers which do not use this engine) which does this feature perfectly with its render object mask in the kernel settings and I have no doubt Corona can do this as well, I just can't for the life of me find out how. The best I have found is of the shadow catcher, but I can only assume this could work if I applied the that shadow Catcher material to the WHOLE scene and render it like that? which just seems like a huge pain to set up as for each element I need to render I would have to have a shadow catcher variant of the scene specifically for it.
Any advice on this?
If I am allowed I'll include the image which demonstrates exactly what I am after.
