Hello,
I have a Mix Material of a Raytrace Reflektion and a Frensl Fallof. In front of thet material are objects which are 100% transparent until a certain point when they appear. My problem is now that these transparent objects are visible in the reflekting material even if they are not visible. Anybody knows why? Can I animate "visible to camera" as well and if, how?
Thanks for helping me out. Tried to search the forum but didn`t find a answer.
I am using max5 with Vray free renderer.

Thanks in advance.

P.S. The problem doesnt occur when I use the default scanline renderer, but then there are very weird reflections(black dots) during the appearance of the objects. ( Appearence is animated over 25 frames)

Right click on the object go to properties and turn off visible to reflections/refractions.

thanks for the answer X96, but the object should be visible to reflections, but only when it is visible, and not the time it is invisible.

Anybody else an idea?

why not do it post?

Or create two copies of each object - one with them being visible to reflections/refractions, and the other without them being visible to refractions. Then keyframe the 'visibility' on both objects over a couple frames so that the objects quicly 'trade places.'
But doing it in post would be easiest.

try to exclude the transparent objects from "raytrace" map by using "local exclude" button.

thanks for all your answers. I think the problem in the first place is, that Vray free doesn´t support real calculated raytracing. What I did now is I rendered the 25 frames twice in which the object appears. Once the object is not renderable and once its renderable. In post I overlapp these 25 frames and animate the opacity of the layer with the object rendered (made myself clear??) now it looks like everything like reflection, shadows and object itself appear over the period of 25 frames.

Is that what you meant with post?

Thanks again!
