Guys

CORONA 12 H1

What is your displacement settings? Try to increase screen pixel (or world unit) size - it could be that you're forcing Corona to process more triangles than it can handle.

If there is plenty of RAM left   it should work...
Lets add this to list of thing new Corona cant handle....

Displacement set to 0.5px

Best thing to do is send in the scene via ticket, at https://support.chaos.com/requests/new . Then we can take a look at what is going on!

I discovered this a while back https://forum.corona-renderer.com/index.php?topic=40964.msg216903#msg216903

I'd still pay extra to bring the old displacement back :)

Now that we've all got machines with NASA level RAM quantities in order to work with Corona, we shouldn't be getting stuck on the number of triangles it can handle.

The more tech advances, the more clients want that extra detail, fidelity and resolution.

Didn't old one worked like world size setting does? Plus autobump now.
And going 0.5px is a bit overkill. Yeah maybe if you're rendering at 2k. But for bigger resolutions you just get diminishing returns below 1.0.
For 6-8k you could probably even go with 2.0px and get really similar results, with way better ram usage.

I'd love to be able to test it and find out
