Optimization of textures

Delazouch

Greetings All

I've become interested with Game environments, I'm using Blender 2.74 I don't think this matters regarding what engine you use.
I would like to know how you go about Optimizing textures for games please, I've tried the baking maps/textures/UV maps on to one image 2048 ect... but getting poor results not as vibrant as the individual model.

Welcome any help on this as fully new to the gaming world and hope to build some impressive photo realistic Environments

Kind Regards

Post pictures of the issues you are having. The only description of the problem you gave us is that your model isn't as vibrant, and that doesn't tell us anything.

As you might see the B Model is as i want it,, A is what i baked to and looks Crap

Actually, the game engine you use makes a big difference!
If it's PBR with a strong material editor like Unreal Engine 4, there's so many ways to reduce the texture size and memory it's daunting for tech artists.

But for Unity and such, it might be interesting to look at mobile games optimizations, as their method is very similar.

How are your textures/uvs set up? For the brick you should be using a tiling texture, not baking it to a uniquely unwrapped map.

I have the Texture in 1048 x 1048, tileable bricks, but having loads of single plains to make up a game map, or scale my mesh to suit the single tileable texture,
Keep reading that i need to optimize my textures to the objects this is where i'm hitting a wall

Sorry if im sounding thick if I was in normal MAX3d/Autocad/Blender doing construction Concepts we don't have to worry regarding Optimizing textures as the GPU handles everything

Could be bad mipmapping if that's in a game engine? I've had problems with UE4's mip maps lowering the resolution far too early.

We need more information. Can you post texture sheets, the object's UVs, information about what game engine you've got it in, etc.?

Here is the full bake map of part of the building. (Please forgive if I'm not posting what you require to help as said this is all new to me)
I was told to use Unreal and found the FBX exporter from blender is very poor so re mastering in Max3d then Export to unreal, At the moment just learning the basics and this optimizing textures for game is the only wall i'm hitting

Thanks again all for help

Don't bake your building texture from an existing model. You should use tiling textures.

If you want to pack multiple textures into one sheet, you need to create the sheet manually.
