William Faucher’s EasySnow on M1 Mac crashes

Did someone manage to run the above mentioned plugin on Mac M-Series chips? My 5.4 and 5.3 keep crashing. It has something to do with the Niagara Blueprint. Can someone please hint me at the problem?

Since this is relatively new, you probably should contact him. My guess is its a bug in 5.4 but definitely let him know.

Thank you. He knows but can’t really help unfortunately. I also tried 5.3. same issue. Even if I try to just edit the Blueprint it crashes.

It turns out to be the problem of substrate features: Overview of Substrate Materials in Unreal Engine | Unreal Engine 5.4 Documentation | Epic Developer Community

If you cannot even open the project like me, here is a possible solution: With the project opened on Windows, go to project setting → engine → rendering → disable “substrate materials”. And then copy the project back to Mac.

Thank you Seagull. So are you saying EasySnow is working for you on Mac? Which UE Version? My substrate materials are off and were never on. So it must be something else in my case.
