Woof…. somebody just smashed full speed into Unity. Reminds me of my first days, too, Lasse - I was screaming foul curses from morning until eveneing and all through the night.
- Your terrain resolution should be exactly 2049x2049, because otherwise you can't really do any small sized work. Even with this higher resolution and even at brush size 1, fine-tuning the mesh/wireframe is very tricky to do and not really advisable.
Think of it this way - anything that needs a really fine wireframe and has a size of 10 meters or less, should not involve the Unity terrain engine at all. it's just too damn rotten bad at that… it's good for vast landscapes and utterly terrible for any kind of precision work. This is were you will need to import and add mesh objects.
We all wish it were different and easier. It isn't.
- You will find the settings for terrain resolution under the little button on the furthermost right of your terrain tools. Careful: If you alter the resolution value, your terrain height map will reset to "flat". Export and save it first, change the resolution, import it back again.
If indeed you did use a 10 meter DEM, then your terrain resolution is currently too small and you need to increase it.
We all wish it were different and easier. It isn't.
- There is no way to add or reduce mesh density to Unity terrain. You pick one value and that's that. The CourseForge will re-arrange vertexes at a higher density when it fuses with the terrain for its meshes, but that process can't be controlled in any way.
We all wish it were different and easier. It isn't.
- it's up to you and your individual style to start flat and add elevation or to import a height map first.
- CF/Unity, unlike the APCD, is not a one-stop and fix-it-all affair. It's a combo of apps that even need to include yet more 3rd party apps for design and 3D creation. It is a completely different way of getting the job done and it represents a different environment and a different design culture so that comparisons with APCD always are a bit "off"...
We all wish it were different and easier. It isn't.
- Yes there is a Unity3D Forum - not here, but over at Unity. There are tutorials and manuals over there. I suggest you make these places your first port of call in case of more problems. A lot can be learned and improved through self-help. You should find answers a lot more quickly by googling unity3d and keywords for your questions than having to ask here and wait hours for an answer, which, most likely will be of no help to you.
Thousands of other people, including me, have run into the same obstacles and felt disgust and revulsion at times. We just want to create a golf course or two, for Chrissakes, we don't want to evolve into uebernerds and have to learn useless junk about 3Dology… We all wish it were different and easier. It isn't.
But further down the line, Lasse, once you learned how to cope with those pesky, irritating, annoying, unfair obstacles, you will find out that it was worth it. Was for me. No pain, no gain.
