I get the artifacts, too. I was concerned that I was not exporting correctly or something.

Here's some more data.

I was using Kerky 2.05 - saw artifacts.

Upgraded to kerky 2.08 - artifacts disappeared in raytracing, but all other render methods showed them.

Upgrade to Kerky 2.09 - artifacts are back all the time.

I was going to post about this at K forums, but I feel like I don't know what I'm doing yet. So I didn't. Plus I didn't want my first post there to be a bitch post complaining of a bug. Worse, what if its not a bug in Kerky, but a bug in Poser export!?!

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
