So the $BlendTintByBaseAlpha 1 it will tint only the white coloured textures? regardless of the other non-white ones?

Thank you, and how to make the un-colour-able thingies transparent?

I would like to thank to Zatemedek for being the only generous person on the internet to figure out, and provide a tutorial on how to paint NON-paintable TF items within SFM.
His video can be found on YouTube, it looks like this:

However, and I haven't tried this out yet... I wonder if we could use this method to paint not only hats, but people as well, such as the Scout, Sollybum, Hoofty, and even custom models, too.

Does it work?

Danke.
