I want to make small-ish mountains for my map but they keep looking like blobby cones with a dusting of ice on top. Is there any advice or guides on how to make realistic-ish mountains? My mountains are small and are mainly intended to be used as aesthetic pathing blockers for air units. To get an idea for how big they are, look at mountains in Civ 5:
My general advice would be to use one of the noisier brushes (last 2) to build up a rough cone, getting steeper towards the center and shallower towards the edges, then paint snow or grass or whatever you want on the flatter parts of it and rock on the steeper parts. From my experimentation, this generally works out quite well.
If you want your mountains the size of the Civilization 5 mountains in terms of scale, you're not going to be able to make them look good. The SC2 terrain editor isn't made for terrain editing on such a small scale. Even if you use the smallest variant of the height and texture brushes to be really precise you're still going to end up with a small blob with ice on top. Normally I'd suggest using the height brush followed by plateau and then playing with the smooth, lower and raise tools, and I think that is probably still your best bet now.
I made a whole map and then realized you wanted small mountains. :D
Basically the same thing the other guys said but here's what i came up with. You can probably go smaller you just have to detail it more. Try a combo of sharpening up the top and then hitting it once with the smooth tool. Eventually you'll get a good point.
Don't think there is a way to change it but you can try and find a really detailed texture by looking at some of the HoTS ones. I believe a couple are high resolution than some of the WoL ones. Then again that takes up one of those precious 8 slots in your terrain.
Thank you! Here is another one I improved after reading the advice in this thread (editor view):
I realized I don't really know what a volcano looks like. One thing I found helpful for mountains was taking the Haven tree doodad and shrinking it down so they look a bit more proportional on the mountains (no giant trees).
I would like to see Weekly Terraining Exercise in the future featuring small mountain ranges. They seem quite challenging to make. The screenshots are from a map called Empires of the Stormy Seas and you can find it on battle.net (NA) if you want to take a closer look at the mountains/terrain. I very very badly need advice!
You could balance it out by reducing the flying height of your air units as well as decrease the height of the mountains. I believe you should be able to find a fitting height that looks natural, yet leaves air easily distinguishable to ground units.
If I can add my 2 cent, what makes the mountain looks weird is not (only) their heigh but the doodads on it. The trees are extremly huge in scale if you compare them to the mountain... I think I would place trees with x,y beeing like 40% and Z beeing 10%, so it would be a flat large tree. Also, maybe do the "texuvset" in the console to make texture smaller and a bit more detailled so you could polish even more the edges.
