Paint Brush size
Hi,
I've a question about paint brush size. When I want to paint some trees on my terrain my paint size (100) is okay, is a good scale. But when I want to paint the grass, with the same size (100), I've a big one, very big! And I've just few grass although my grass density is max ! My second problem is when I want to paint a way with my texture my paint brsuh is 1*1 but I've a big square !
This square is 130 m long but I would like just 3m. Some people have an idea? I work with a big environnement. An island, 50km/50km. Represent on a Unity terrain 50 000 1800 50 000. My heighMap resolution is 4097,baseMap resolution 512, details resolution 1024 and detail per patch 128. I use Terrain Composer to make my Terrain. And Tom Terrain Tool to place my tree. Thanks a lot in advance.
If you want to paint terrain textures more precisely (have a smaller paint brush square) you need to increase control texture resolution.
In the terrain Assets, if you expand the Terrain, then the Control Textures are listed as Splat0, Splat1 ... . Texture 1,2,3,4 are stored as RGBA. When you paint that single blue square above with texture2, you are really changing 1 pixel of the control map to greener.
Just looking at the Splat for a painted terrain should give you a pretty good feel for how the control map works.
I know this is an old thread, but I've spent hours looking for a similar question that I could not find the answer to.
Click on your terrain, this should bring up the terrain tools in the inspector window. Click on the gear icon, scroll down to control texture and adjust it from there.
I am working with real world terrains and have been trying to adjust it through the RWT settings, but when I changed my settings the said way above it finally allowed my paint brush to be a smaller size.
Again sorry for replying to a 4 year old thread but this is the first link on google so if others have this issue in the future perhaps they will be less frustrated and break less things, in their 
game and real life, looking for an answer.
To be fair, googling "unity control texture resolution" took me to a page in the official Unity manual with this same picture (but it didn't have the arrow or yellow highlight.) Sometimes the problem is just being overwhelmed with so much new stuff.
