You do not have any debugging symbols required to display the callstack for this crash.

.i succeeded to recreate the bug and i think it’s foliage instance related .I installed the 4.13 preview and i can open my scenes there.unfortunately Substance plugin isn’t available yet . So i need to make it work in 4.12/

at first i though it was this BUG But i tried to change the cpp file and it’s still the same . I’m out of ideas and i got a deadline very soon …
I would install 4.12.4 and convert back but i have no idea how to do it.
Please if you got anything that would be awesome !``

Thanks in advance

Hi,
I’ve posted workaround for this crash here Level crashes after adding foliage - World Creation - Epic Developer Community Forums

If you change those lines in rebuild Edtior it should not crash anymore.

Thanks for the very quick answer !
Unfortunately , i don’t have visual studio and i don’t really know how to rebuild the editor …I’will try to open it in a prior version.
How can i download a version 4.12.4 ?

Or i’ll rasterize all my substances texture for the time being
Thanks again
