How to make the generated mesh readable ?

[Anthonyk]

Hi !

I wrote a  mesh deformer script which is modifying mesh vertices at runtime.
It was working great with another plugin "m*ga shap*s" : https://vimeo.com/278707282
But I decided to switch to Curvy for better features. The only issue I have is that the generated mesh is not readable :

"Not allowed to  access vertices on mesh 'Combined Mesh (root: scene) Instance' (isReadable is false; Read/Write must be enabled in import settings)
UnityEngine.Mesh:get_vertices()"

I tried to use mesh.UploadMeshData(false) inside the "CreateMesh" script, checking/unchecking the "combine" option, generate the .mesh asset, but it makes no difference. 
Do you have any idea about where and which code can I edit to make the generated mesh readable at runtime ?

Thank you so much for your support !

Regards,
Anthony

Hi,
I am right now on vacation, with no access to a computer, so I can't provide you with a tested solution.
In this page https://docs.unity3d.com/ScriptReference/Mesh-isReadable.html, it is said that "A dynamic Mesh created from script always returns true". This makes me ask "Are you using the dynamically generated mesh?". If your answer is Yes, then try generate a .mesh asset, and use it after setting its "Read/Write Enabled" in its inspector.
I hope this helps. Please let me know if you still have the issue, while precising the Unity and Curvy versions.

It works ! for some reason the "static" checkbox was checked and this why the mesh was not readable...
Thank you for your great help !
