Sorry for the stupid question (also I'm not sure it's right thread for it).
But... How to rotate the camera (Editor mode)? I've tried all keyboard keys, checked all toolbar buttons and haven't found anything. In camera Game mode I can easily use in-game keys for the camera rotating, but Game mode has some limits like zoom distance, camera moving speed and so on – which is not comfortable for editing.
Middle mouse = pivot camera. Basically hold down middle mouse whenever moving around. Makes it move kinda like an FPS.
Adjust camera speed is shift or control. So hold control + middle mouse + WASD/Arrow keys to go slow. And use shift instead to go fast (not that useful).
Also, if you just read through this forum using the default forum settings it cuts off threads at like the last 6 months. If you go all the way to the bottom, click show topics: From All Dates. There are a lot of old threads people probably don't see because of that. Some of the info is dated and wrong but a lot of it is valuable. Same thing when searching.
If you have any random questions like this feel free to post them. Or you can add me on Steam and bug me that way, username SniperHF.
sometimes I can change a terrain, sometimes I can't and there is no messages/errors/hints for such cases.
Are you talking about textures or shape?
If you are editing the terrain, try making sure that particular piece of terrain is selected on the terrain panel.
Is there any VERY BASIC editor UI description?
Not really.
