Baked textures for a large terrain look blurry / pixelated

sevek

Hi, i created a terrain in Blender which i would like to use in Unity. I don't want to use Unity's Enlighten for lighting so i baked all the stuff (diffuse, lightmap, ao, etc...) into a single texture using Blender. After importing this to Unity the results are quite dissapointing - texture is blurry and pixelated and is very far from having a crisp and clean look.

Blender render:
 

Unity:
 

I'm aware of what's causing the issue. The terrain is quite big (around 5km x 5km) while the texture i'm using is 1024 x 1024. So the question is: do you know how this issue can be overcome ?
Obviously i tried bigger textures (up to 8192) but that doesn't help much. Naive solution would be to split the terrain into a smaller parts and texture them separately using hi res textures but that sounds very tedious and i'm wondering if there is a smarter way.
I would be really grateful for any info on that. Thanks.

Can I see a pic of your texture map?

You could use material IDs and assign different IDs to the polys.

Yeah I wouldn't use texture for this. Split the model into three materials, then you can just use color values in the Unity materials.

Here's how texture looks like:

Thanks for replies guys.

I was trying with spliting model into 3 parts and using just colors in Unity and it works in general. But the render made by Unity is not as visually pleasing as the render from Blender. I just cant replicate the same look in Unity, that is why i was using aproach with baked textures. Maybe i was not trying hard enough, i guess i will give it one more try. I think we can mark this as closed.

You just need a shader with flat shading. Then it's just setting up lighting.
