Relative scale of textures

[Xylent]

I'd like to know if anyone has any recommendations on what to do about texturing very very large objects in UDK.

To put that in context, let us say I am using a 1024x1024 pixel texture for a 256x256 unit wallpiece, all other objects that fit in a 256 unit cube also use a 1024x1024 texture. For this particular case I am not actually talking about making a very tall wall but irregular objects like large statues, long boats, large wooden beams, big doors/gates, etc. -- things that normally aren't tile-able mesh.

What if I wanted to make something really big -- like 4x the size?

Should it use a texture that is 4 times the size with the UV in relative scale to all other objects' UV maps/islands?

Is it better to just cut up the model into several smaller pieces, tiling pieces where possible, and assemble them in the editor?



PS. I'm mostly using this for just creating a scene, not really for gaming purposes so performance isn't really a big deal but I do try and optimize where possible.

It is often good to cut the meshes in smaller pieces , but instead you can use something like let's say 4k texture map for it + overlay it with some detail texture of some smaller size , i think that is a good way for some big rock for example , use overlaying only for really big meshes , if it's not big then 4k map is usually enough .
You can look at UDK rocks materials which are using many tiles for specular map .

Do you happen to know any resources and tutorials specific to optimized texturing UDK static mesh particularly irregular objects / not wall pieces?

Thanks
