How do I remove the black dots when objects cross eachother.


This might sound weird but for example when I make a cross with two rectangles when I then render the image the place where the two objects cross over it creates black dots. Is there any render option to remove that?

@itzCatz:

I cannot seem to replicate your problem. Can you post a .blend?


Ok like that. :stuck_out_tongue:

Does anyone know what’s causing it?

@itzCatz: Your problem is “z-fighting”.

I have read that LuxRender handles z-fighting in a less ugly way, so you could try that.

Really, though, I think you could find a way to model the shape so that it works. How about applying a “Union” Boolean Modifier?

rking is right, it’s called z-fighting and you can read about it here:

For the object you are showing in the first post, just make sure you have no faces overlapping where the 2 rectangles meet. See attached file.
