Unexpected render issue

Recommended Posts

Hi Folks,

looking for some advice here.

Any thoughts why my extruded "pilasters" have the Black lines when rendered?

everything else renders fine in this mode.  and I have changed a couple of things.  

Each time I render it looks great and at the very last second I get these black lines on these objects only.


any thoughts?

This is generally because you have some wireframe geometry that does not have a fill. Could it be that you have unfilled duplicates of your pilasters on another class that is only visible in your viewport?

Ahh Multiple copies of extrude  " Coincident objects  thx mark 🙂 I think that fixed it

I do like coincident object selection tool    J + HOLD > Click    to select the extra stuff an unsung hero tool

Are later viewports rendering correctly, or are they completely black? When you said ‘at the very last second’ I was thinking it might be a gpu issue, ie that the card is ‘full’…?
