- Running bpy.types.Particle.uv_on_emitter() results in unexpected behavior, including returning nan, 0, <number>e-40/e+40 in different combinations and eventually giving an EXCEPTION_ACCESS_VIOLATION crash. The behavior is present when accompanied by viewport updates of any sort and having other modifiers on the mesh. Open the attached file and run the uv_on_emitter_crash script multiple times.
- Running bpy.types.ParticleSystem.uv_on_emitter() results in an EXCEPTION_ACCESS_VIOLATION crash if the particle parameter is not specified. Open the attached file and run the no_particle_crash script.
