Bug / Crash Trouble with particle editing and Prefabs. - 2018.3.13f1

[jabza]

Hello,

I recently updated my project to both ObiCloth 4.1 and Unity 2018.3.

My project uses prefabs, nested prefabs and prefab variants. Whilst working with ObiCloth I have encountered a few issues regarding Obi Pins and Obi Handles.

Defining Pin constraints in the Prefab editor simply does not work. References to the Pin object are not preserved. I am forced to unpack the Prefab, modify the ObiCloth, and re-create the Prefab. 

I've noticed a similar problem with Obi Handles, they do not a appear in the hierarchy when creating them.

I think the issue may be in part due to how the Prefab system recognizes objects as 'changed', as modifying many of the ObiCloth attributes does not appear to result in a 'dirtying' of the object, which may be causing some issue elsewhere?

Any support on this would be greatly appreciated.

Thanks in advance. Really impressed with the continued support and enhancement of this fantastic asset!

Hi,

Take a look at this -very similar- thread:

Of course, since prefabs do not support references to anything outside the prefab hierarchy. So if you add a pin constraint to something that's not part of the prefab, it will not be preserved. Same behavior as the old prefab system, Unity prefabs have always worked this way.

I've noticed a similar problem with Obi Handles, they do not a appear in the hierarchy when creating them.

Because they're not created as a child of the cloth itself. That would defeat the purpose of handles entirely, which is to decouple specific groups of fixed particles from the cloth's own transform, so that they can be controlled independently . Handles created at the scene root, outside of the prefab, and you're free to unpack the prefab and include them in its hierarchy if you wish to. Again, same behavior as with old prefab system.
