[SOLVED] Random crashes when flying over terrain

[demostenes]

Since 2.9 I ve experience crashes when just flying over terrain. Load /esqworld/esqworld_MC.world (change set 1087), set camera speed 3 and fly over forests. It should crash very fast (surprisingly not in the city, but in forest, which is by far less demanding). After migration from 2.8 I ve deleted all .cache files, shaders cache, etc... I know that this world  and especially cities are absolutelly unoptimized (it is WIP, mesh merge will be done later), but it wasnt crashing in 2.8. Nothing in log, just generic windows crash dialog "cant read memory...¨

There were multiple changes in clutter / grass internals in 2.9 release, that's probably the main reason of this crashes. We will check what we can do about it (more likely within a week).

Thanks for the bug report!

Hello,

We're testing the fix at the moment.

The plan is to include this in the next hot-fix release (2.9.0.2) which will be available in the beginning of the next week. Of course we'll try to finish everything faster.

Thank you.

2.9.0.2 update is uploaded, you can try to download new version to get rid of these crashes.

Thanks!

Seems OK now. Thanks.
