Another one? Yes, I've started a new editor inspired by Rondidon and ... my own post. Right now this editor only supports drawing blend maps for terrains and models (with a hmp like UV mapping).



It's the first version with hardcoded textures and the like but if you're interested, I will release a useable open source version soon.

The blendmap & shader currently support 4 textures, but I will add support for a 5th texture later. The blendmap (extern, filename_blendmap.tga) is entSkin1, the other 4 textures are material skins.

Controls:
Move the camera with WASD + right mouse button, paint with the left mouse button on the active channel (currently you cannot click the textures on the right bar to activate the specific channel, but press 1,2,3 or 4 or use the slider to switch between channels).
Erase channel with Shift + left mouse button.
Ignore higher layers/ paint opaque over all other layers with Ctrl+ left mouse button (or check the box on the lower left).
