Hello...

when I render in Poser in the Firefly engines at Final Settings i often have 1-3 little black lines in the final rendering.....see above example....

they  can be vertically...and horizontally

Anybody know why this happen and how to avoid? It drives me mad render a Scene 20 minutes and than get this :(

I have the same issue. I have noticed while watching the image render, those black lines appear at the edges of the little render box ( I'm not sure if thats what you call it but the image renders one little box at a time) maybe trying a smaller bucket size (under manual render settings max bucket size) I don't know if that will fix the problem, I usually use the healing brush on them in photoshop. 
I will be curious to see what others say, thanks for the post.

Try setting small displacement bounds, like 0.2 or so in the render settings.

Yes, this fixes flat surfaces for me, like a square background. I don't usually get those artifacts on curved surfaces, like V3 or clothing.

Thanks much!

I will try this!
