high res splat maps

I’m just starting to learn Unity so this might be a simple question:
Can I use/display high res splat maps? I’m looking at using Unity for college campus planning want to be able to model an area around 300 acres (100+ hectares) have the sidewalks, roads, etc. have reasonably sharp definition. I’m basically looking at bitmap resolution between 4096 8192px.

You might have to split up your terrain to get the resolution you want. Also, sidewalks and other position/orientation-dependent features should be done with something other than the terrain engine.

It doesn’t go higher than 2048 for me, but that may be a limitation of my graphics card, which won’t go above 2048x2048. Keep in mind that many cards have that restriction. You can divide the terrain up into multiple parts though, so the total can be as large as you want.

Yeah, I thought it might come to splitting up the map. That’s how I’ve had to do it when working in sketchup. Thanks.
