Hi everyone,
I´m working with a big model and I get strange render results.
Part of the model:
There are no gaps between buildings and terrain, you can see this in the arctic preview:
So why do I get this strange render result? The magenta light is placed behind the buildings but seems to leak out under the buildings. And there are strange shadows that shouldn´t be there.
For better understanding: that´s the position of the lamp:

Hello - does it do this if just the few buildings in the image and not the terrain at all, or just a small bit of it, are showing ?

Hi Pascal, a reduced model shows the same behaviour (everything not showing was not only hidden but was deleted).

I should add that there always was a huge mesh model hidden that I used to create the model I actually rendered. But the behaviour stays the same after deleting all meshes.

Hi David - does a full render look correct? So far your model looks OK here - can you please run SystemInfo
in Rhino and copy/paste the results here?
@david.adam - your objects are very far from the world origin:
Point in world coordinates = 534868.661,5685399.260,167.551
Moving them closer in should help - I understand that may not be ideal…

That fixed it! After moving all objects closer to the origin the render result is correct. Thank you!
