I need feedback (chair and collisions) (Patreon)

Well it seems that blendshapes are a not a good idea for assets. Few people have told me that this method doesn't work properly for them, so I would like to ask more subscribers what they think about blend shapes. Your answers in the comments will help me decide whether to continue using the add-on in future.

I would like to know your thoughts on points:

1. How clear were the instructions for using collisions on assets? Perhaps my english wasn't clear enough?

2. Can you tell me when you clicked the button your fps freeze in game for a long time?

3. How good is the blendshape system? Does the inconvenience of 'updating collisions' outweigh the usefulness of being able to configure assets in the scene?

Feel free to share your thoughts
