BTW this contains the sourcecode, useful to save B3D meshes with masked textures.

I'm fine, thx, hope you too.
This code uses vertex color, but has the alpha in the texture of the trees. The B3D saving code has some remarks, should be possible to mod it so it will use vertex alpha. In the CSP engine update there are some tools, one is a terrain splatting tool with up to 8 textures, with sourcecode, and can save B3D.
btw, Game Jam 2023 is now on-going, perhaps you got something in there brewing that would make an interesting entry..
