Hi Guys,

16.2.4 has a strange issue with displacement (the ground plane):

Here is how it looks when rendered on previous versions:

Thanks,

Just wanted to add that it's the same in the viewport as well:

The displacement is just on a simple UV unwrapped plane.

Hello Jason!

Would it be possible for you to share you scene (no spider needed!) so developers can test it and understand what's wrong?

Thanks!

Hi linograndiotoy,

I think I have figured out the issue. It looks like when 16.2.4 reads in an older version's blend file, it doesn't set the displacement node parameters correctly. You can see here that there are two items that are not being set and must default to a lower value.

If I then set the displacement level parameter correctly 4096x4096, the displacement looks correct again:

Just to test I set the level to a very low value and it looks bad again:

Thanks,
