This is a kind of awkward situation.

This function "bpy.ops.sculpt.dynamic_topology_toggle()" toggles dynatopo sculpting. Some addons including mine need to check and disable the dynamic topology so that we can access, copy or change the BMesh elements custom data layer properties (masks, weights, etc).

Here is the problem ; If I disable dynatopo from the ui and execute the script, everything works as expected. When we use the toggle function from script; the script executes without any errors but as if dynatopo wasn't toggled off (so the results are not correct).

Testing :

Mask Tools:

You need to install the addon using "Install from file" or if you want to manually install, then all files need to be together in the blender addon folder.

Steps to reproduce :

In sculpt mode make sure dynatopo is disabled, paint a mask and in the tool shelf select sculpt tab/ mask tools
when you click "Create" in "Vertex Group" section on the tool shelf, it will convert the mask to a vertex group.
now clear the mask (alt-m) and click on "Create" in " Mask" section on the tool shelf, this will convert vgroup to a new mask.

With dynatopo off the script works but with dynatopo enabled it doesn't.

If you enable dynatopo and repeat the same steps the script will either return a blank mesh or a random masked mesh.

So I toggle dynatopo off with "bpy.ops.sculpt.dynamic_topology_toggle()" function in the script.

When I check and print it on the console it also returns that it is off, but the results are as if it is turned on.

Line in which toggles is maskToVGroup.py > 27

Check at maskToVGroup.py > 29
