First of all I’m completely new to Unity. I want to do a classical level-design where the object has to reach the top of a mointain along a path. The path should go only around the mountain and it should end on the top of it. I found the terrain-menu bar where I was able (with the 2nd button) to make such paths only in a certain hight. But I need such a tool where I can draw a static climbing path.
I’m not sure what you mean by drawing a static climbing path but pretty sure there isn’t any tool for doing what you want. You only have the lower/raise terrain tool and the smoothing tool (unless you implement your own tool using Terrain.SetHeights).
Also your mountain’s textures will look very stretched out when you make a steep mountain side like that since the UV resolution isn’t increased based on height (the textures are just applied from above so to speak). You probably want to mix it up with some custom cliff meshes so you can have textures with more resolution at the steep side. Here is a link describing what I mean:
Update: And as a general tip I would advise you to apply some kind of texture to your terrain while shaping it because otherwise you don’t really see very well how it’s turning out.
Way I would do it, create a spiral with any vectorial program, apply a gradient to it, import it as a stamp or a heightmap, finalize in engine or adjust scaling by iteration.
I just needed a similar path and ended up buying this;
It allows you to select 2 points on the terrain and it draws a straight line between the 2. I was able to get the paths I wanted with this simple tool.
Now I’m just trying to work out the performance problems with terrain.
