Hey Juxols,

I just attempted to reproduce your crash in a new blank project, but did not get the crash to occur.

Can you provide me with your crash logs and your ‘dxdiag’ so I can investigate further?

Let me know if you have additional questions.

Thanks,

it’s only happens when using “kite demo” assets.

Looking through our internal crash database at your specific crashes, what you are experiencing is a known and reported issue. Your callstack is identical to the one that is generated when modifying any SpeedTree asset’s LOD through the mesh reduction tool.

The link above will provide you with more information on the ticket that was logged for this issue. Once the issue has been addressed by our engineers the ticket will be updated and reflected in the public tracker. Let me know if I can be of further assistance.

so how do i fix this or do i just wait update to fix it?

You can wait for the fix, attempt to fix it yourself in code, or you can avoid using the in house mesh reduction settings for now. You could also go back a version and work in that if it is blocking you from production.

Thanks,

Still happening in 4.15.3
