disabling reflections

[joethelion]

How can I disable reflection of an object on a reflective surface ? It is possible to do the opposite (by checking `only visible in secondary`) but not this. I understand this can be done in max through object properties but couldn`t find how to do it in SU.

Thanks!

you can change the mirror material to exclude materials from reflection.

hope this helps.

Thanks, I already saw that one, but first of all didn`t understand how come the shadow is still visible in the last image (if the mirror mat has `exclude materials from reflection` checked).

Also in my case the mirror should reflect everything else, except just one object.

I'll see if I can dig up the file and post it. As you can see only the tree was excluded.

that would be great !

So here's what I found - as long as the geometry is connected (and all in one group) whatever is with the mirror will reflect. Anything else in another group, even nested in the mirror group, will be excluded from reflection.

I can`t see the attachments (not allowed for some reason), but the idea makes sense, I`ll try it

I have the same problem. I want the object to show in the render but not reflect on other objects in the model. Any info would be great thanks.
