Min max issue, driver error

[loicbramoulle]

Hi, first off super essential addon ! Just now I'm using it again on a Reallusion character, I made some facial hair mesh with Hair Tool addon, and when transfering shapes, the max is set to 0.001 instead of 1 (or the value I used on the face mesh,1 or 1.5) And when binding shapes, the driver has an error, it doesn't find this data path on the face mesh, but it seems correct: The data path looks like this when copying from the face mesh: key_blocks["Nose_Tip_R"].value

For the min max it's easy to set to 1 with the Shapekey Extra addon.

But the driver it's so strange it always worked directly before...

The object coordinates are all applied for all meshes, all parented to the rig.

Maybe it's some attribute ?

Hi. Quite strange. It works well for my cases. Does it fails to setup max driver only, and there is a problem with main value driver too?

It would be great if you can share the problem file, so I can directly see the problem and debug it in real-time

Thanks, trying to isolate a test file I realized it is caused simply by having a subdiv modifier on the source mesh. If active in viewport it makes drivers red, if subdiv disabled then the drivers are correctly setup.

Thanks.
