I've run into a couple problems since migrating to Unigine 2. The first is that I can't paint on the terrain mask. The diffuse, holes, and heights brushes all work fine, but the mask brush has problems. I set the brush to "replace", selected a material, maxed out the brush's radius, sharpness, and opacity settings, and set the limits to 0, 90, -100, and 200000. When I press ALT+LMB to draw, there's a lag spike that lasts about 3 seconds. When the lag ends I can scribble on the terrain, but nothing happens. Occasionally I'll see a very slight change in the textures, but it's almost nothing. All the terrain files are unlocked, and the console reports they're being updated and reloaded properly.
Also I should note here that occasionally when I cancel the terrain edit dialog, and hit "yes" on the popup window, the edit dialog disappears, but the brush remains active, and menus are disabled. Then I have to restart to fix it. This is rare, but it does happen.
The other problem is I can't edit clutter masks. I'm using the same masks I was using in Unigine 1, and they work with the clutter objects. When I try to paint with the mask editor however, the console spams this error:
Image::variable_to_pixel(): unknown image format "R8" for "dvec4" variable
Editor::update():editor update function return 0
Has the image format for the clutter masks changed? I haven't seen anything about this in the documentation.
