AddBlendShapeFrame() reset between two editor runs

Hi,

Is there an easy way to reset the editor's cache for blend shapes?

Basically, I have a script fetching data and applying a blend shape at runtime on a mesh. After the first run, the sharedMesh itself gets changed (which makes sense), but I can't apply the blend shape anymore on other runs because it exists.

Is there a way to either remove a blend shape programmatically, or clean the added blend shape through the editor?

Thanks!

 

I'll be honest that I don't know much about blendshapes, but if your intention is to make it runtime only, why not instantiate a copy of the mesh before modifying the data instead of using the shared mesh?

 

Because I will need to duplicate the entire memory :/ I don't know how the blendshapes are stored anyway in the GPU context, so depending on that there also may be an entire duplication of the GPU memory.
