Hi,
I have a big problem rendering a picture 24000 x 19000 px.
Strange artifacts appears and I can't fix it.
Please see pictures an attached sample file.
If anyone have a idea, please! Deadline is the 13.08.07 and the picture takes 17 hours to redner;o)
I've tried
- facet-sop
- poly-doctor
- scale the whole model

It's imported via PolyTrans from STEP

Thanks
Detlef

The problem comes from your shader and displacement.

Dive in your shader and disconnect DispOutput (at the bottom).

Hi,

thanks, too late but for the next imported models I first check the shaders.
I had two problems, one I solved with your answer and another thing is the “Tangent Style”.

What version are you using ? Because the displacement bug is resolved from a long time ago. And perhaps your problem with tangent style is the same.

And if your shader is imported from another old file, becareful, because his definition doesn't match the version you are using.

I work for my customers over years and it always need the same look, and it's stupid to rebuild shaders every time a new version is out
I use 12.5.427 and yes “old” shaders what seems to be the problem…
Thanks
