Problem summary Cyclical Dependencies created with instanced Particle Operators crash Modo. Older versions of Modo error with "Error: Attempting to run the simulation failed."
Customer reported version modo.12.2v2
Customer reported platform windows10
Steps to reproduce 1) Open Modo. 2) Open the attached scene. 3) Select Dynamics > Preview Animation and wait. Result: Modo will crash after previewing several frames.
Expected behaviour Modo should not be able to create cyclical dependencies that will cause a crash.
Actual behaviour Modo can create cyclical dependencies that will crash Modo by using instances of a particle operator.
Workaround Create a non-instanced copy of a particle operator instead of an instance.
