IMPORTANT TEMPORARY NOTE: This addon may not work in Blender 4.0 yet. We will make an announcement when our addons are fully updated for the latest Blender version. We are sorry for the inconvenience. Blender 4.0 was a major release, making many changes to Blender's API. Therefore, updating the addons requires careful testing. Thank you for your patience and understanding!

This is a simple Blender addon that will set up your Weight Paint options so that you can paint on back-facing polygons (a.k.a. "paint through the mesh").

This is possible without the addon but you have to correctly set 3 separate Blender options. The relation between them is not obvious.

Once the addon is installed, you can enable the right settings using a single button:

Pricing

The addon is available as "pay-what-you-can". We indeed ask you to pay for the addon... unless you really can't afford it. Then you can get it for free :)

The recommended amount for this addon is around $3.

Manual Workflow

If you want to do the same manually, you have to set these options as follows:

Front Faces Only: OFF (Default: On)
Falloff: Projected (Default: Sphere)
Front-Face Falloff: OFF (Default: Off)

If you don't want to use the addon here is a mini-tutorial on how to set it up manually. It may not seem like much but the settings are all over the place. I personally think it's a headache when you have to turn them on and off repeatedly.
