Render crashes at higher resolutions

[gummipolarbear]

I’ve been having random crashes while rendering ship in ocean scenes at higher resolutions (3840x2160 or higher). I’ve isolated it to the ocean itself but unsure what would cause it to crash on some camera angles and not others.Sample scene here https://www.dropbox.com/scl/fi/x9f8um56vfq5qd5x7u3c2/ocean_testing.zip?rlkey=qdiv8hkkpwjr7zqay4dtjh4mk& st=o8vzwwtb&dl=0

In my experience, the Ocean Subdiv setting can cause crashes or memory issues at higher resolutions. The default value is 2, but since it’s based on screen size, rendering in high resolution generates a huge amount of polygons. If you run into problems, try lowering it to 1.5 or even 1.0 – this usually helps keep things stable.

As for fixing an unattractive horizon line, one workaround is to render a separate pass using just a plane for the ocean with V-Ray Displacement, and then blend that with your main render in post. I render it with rendermask on in V-ray to save rendertime.

Thanks, that seemed to fix it. I guess having the Ocean Subdivisions at 4 didn’t help at all lol. Not even sure why i had it so high.
