ParticleModelShape stops working when copying effect to new project

We have an external technical artist creating complex 3D and particle effects. When trying to copy an effect from one project to the other the ParticleModelShape-component bindings stop working without any warnings or errors and even setting its scale directly does nothing.

A workaround is to use ParticleShape3D instead, which requires some tweaking to use but doesn't seem to have the same issue.
