RT/GPU - Hints of Shadow with Visibility Keys?

[Alan Iglesias]

I'm getting intermittent hints of shadow while an object is on a 0 visibility key...anyone see that at all?

Thanks,

Hmmm...looking closer, it's hints of the shadow and the object that are rendering...

With a simple scene, it work for me :



I'm using the latest nightly though.
If you'd like, you could probably strip your scene down and send through PM to see if it work here.

Yes, a scene file will help to find what's going on.

Dang, I've been hit by a huge deadline lately - sorry to not have been back to this thread.

Stan - Thanks for your test (i'm still on the last release build). And Tashko, yeah, I'll try to get a file to you when I get a break.

Thanks to you both!

Well, looking at my last render I guess I got rid of it! He-he, I guess I was too tired to remember to check after rendering. The offending objects were in a group and I think perhaps there were conflicting/redundant visibility keys on objects and the group. My last move before rendering was to remove all vis keys from both objects and groups, and then re-apply them just to the objects. And it worked so there you have it!

Thanks guys,

Hi Tashko,

So...now that I've gotten some sleep(!)....I remember that the particular render I looked at last was a CPU non-RT render! So I have isolated the objects in the file below for you to see.

Just scrub the time bar while RT/GPU is running and you'll see that when the crane's visibility keys are at zero, there are remnants of the crane still rendering - in "thin air" as well as from the shadow when the building is there.

I hope you can figure it out...

Thank you Alan. I'm looking to it now.

Managed to reproduce render artifacts with your file using the latest official version, but it seems to work fine with the V-Ray 3 nightly builds.
I'm going to check now whether the fix will be included to the next SP.

Update: Yes, it will be better with the next SP release.
