I’ve prepared a small video tutorial on how to paint onto skeletal meshes without using C++ or any plugins.
Video Link Here
I’ll also write down the tutorial in text if you’re not a fan of watching videos.
Basically we’ll need 2 texture render targets
1 RenderTarget to unwrap our mesh
1 RenderTarget to accumulate our paints
We’ll also need 3 materials.
We’re using this material do blend between the default material & our painted material using the alpha channel as our mask
First we’ll need to unwrap our skeletal mesh from the UVs so let’s create a material for that
Then setup our actor & scene capture for the unwrap
Make sure your settings are correct.
Then to unwrap do something like this
And finally here’s our material to project our texture onto a skeletal mesh.
Make sure you’ve got AlphaComposite enabled.
Then here’s our paint function
