Matte/shadows

[pablog]

If done a couple of experiments using matte/shadows for a camara match but havent been able to get it to be transparent and to only render the shadows. Thanks

have you checked 'opaque alpha' and 'receive shadows' under the matte shadow material rollout?

If I understand, just uncheck "visible to camera" in the object's properties.

Actually I was experimenting w/ that yeasterday and in the max matte/shadow material you don't need to check "received shadows"...but in the object proprieties for vray you need to check "matte object", and set the alpha contribution to = -1
then it works....the matte object will not be visible to the cam.

it should still work though...

i've been using matte/shadow for a series of renders where i had to comp objects into photographs over the last week without any problems...

are you trying to render out only the shadows in an alpha channel to comp onto a background later, or are you just trying to get shadows to show on a matte/shadow material?

can you post an image demonstrating the problem?

I found an error with objects properties menu. These scripts don't work. Anyone get an similar errors? Is this a bug? I'm using vray 1.09.03m in max 6
