Artifacting with overlapping clouds?

Hi there.

I’m working on a scene where I have two different clouds, one behind the other. I’m using the cloud generator script for these. When I render I get an artifact where the bounds of the background cloud and part of the cloud itself show through. The clouds aren’t touching at all, so I know it’s not a clipping issue. Any way to get around this?

Here’s a picture of what’s going on.

Can anyone give a hand with this?

For something like that, you’re probably going to need to post up a blend… I know I hate doing that too… :frowning:
