No depthmaps, its all raytrace, with one dir-light.

But I started doing some investigation work today...

I deleted everything on the other layers, besides these two shapes, as shown in the pics.

At some point during the last detetions, a new render showed no artifacts, where there had been so earlier.

But did not find out why this rendering-artifact occurred.
I have always taken comfort in rendering the objects shown on the screen and thus making them show up on the rendering (of course), but...

...now I found out that my outliner showed LOTS of "unknown" nodes, of various types.

...so I deleted the HUGE amount of exessive group-nodes and such, until the project was really cleaned up.

Although I dont know why the rendering-artifact appeared in the first place, they are now gone.

Maybe my computer couldnt handle all the action, or maybe I'm wrong.

Hopefully this can help you guys in figuring out why the r-artifact came about.

Some kind of "artifact theory" would be nice, if anyone knows about this, or have an idea of such.
