How to import large detailed objects in unity?

Questions & Answers

So far ive been getting by with repeating textures. My workflow for small unimportant objects is…

  • Make mesh in zbrush or maya
  • UV laid out
  • Import to unity
  • Assign texture to mesh in unity

and thats about it. It works and looks good for small things like wood or rocks. However what about detailed objects? This is what i do and im sure its wrong…

  • Make a mesh
  • UV laid out
  • Paint in zbrush, export texture
  • Assign texture to mesh in unity

In my case i need a detailed cliff (side of a mountain). I have no idea how to make big objects in zbrush or maya and import that into unity. How do i determine the size? Ive just scaled it up in unity but i think that may be why my big detailed objects are blurry? I also think it may be due to UVs?

In blender i remember just upscaling the UVs a crazy amount and i always got sharper repeated textures but what what about textures that arent repeated?

Basically what i need to know is how to determine the size of an object in zbrush for unity and how to make a sharp texture for it?

If you’re going to make a sharp texture for a large object, you will need a really huge texture. Like 4096x4096 at least. But this will make your game slow. What you want to do is use a tileable cliff texture and scale the size of your cliff, and then, in the Inspector in Unity, change the Tiling x and y values for your material. It’s pretty much the same technique as you did in Blender as you mentioned.

Also make sure you check your import settings for the texture to make sure it’s at the resolution you want.
