matte shadow and Vray physical camera problem

[Clifton Santiago]

Maybe I'm just doing something wrong, but I can't seem to get matte shadow objects to render properly with Vray Physical camera. Instead of showing through to the background, they are just rendering black. I am assigning the matte shadow via Vray material wrapper. I am not having any problem when using Max standard camera.

Yeah, same problem here. I tried setting the ground plane to all sorts of matte properties (through vray poropeties, override mtl, alpha 0,-1, etc) and they all rendered black. I thinnk it worked fine if you uncheck "exposure" in the camera but that's not the point. I've noticed the background is showing up, it's just very, very dark. I think it's a bug of sorts. Best solution I have other than using a regular camera was to uncheck objects as "visible to camera" - they cast shadows and block GI but at least don't show as black but won't receive shadows AFAIK.

I'm having this problem as well, using vray 1.5.00.

Did anyone come up with a solution for this using the physical camera?

Thanks,

Works fine for me... what is your background in the first place? If it is just a solid color or a texture, it probably ends up darkened by the exposure of the physical camera, in which case, you just need to make it brighter.

So I've made a change to the matte/shadow stuff to be handled as an actual background; if there are not problems, it will go into the service pack.

Nice one.

Do you have a scheduled release date?

Thanks,

No, but it should be soon-ish; we've done all that was planned so if there aren't any more issues during the testing, it will be released.
