Any blender fags here?

I'm currently playing around with Unity3D which has GREAT built in out of the box support for blender - incl. reading .blend files and auto updating.

Mostly coming from the level design area though, I grew up using BSP brushes which are slowly becoming outdated, but are generally great for the layout of a level. Seeing as unity doesn't support bsp brushes, I'm going to use blender for all of my level geometrie (which is at the moment not more than a few basic rooms connected)

Due to gray rooms being kinda boring, I decided to UV map a room and giving him basic textures which worked like a charm. I then did cut the room up further and extended one side into a corridor (which of course fucked up my UV maps again)

Question #1) Is there any method of 'copying' the UV maps of one object onto another? Say: I have two identical rooms, can I simply unwrap room 1 and put his UV maps on room 2?

#2) Is there a way that prevents UV map stretching? I.e.: I create a square floor and UV map it correctly, later on decide I want to make it rectangular resulting in half the width, which fucks my UV maps up again, I'd have to update them for half the with. Is there a method that would 'automaticly' update this change (kinda like the work with bsp brushes)?

Will bump with random cg art I guess.

select the objects that you want to make identical, selecting the main one at last and press ctrl + L, select object data will also copy you uv's.

Basicalley , select object A + Object B, ctrl + L link and Object A will be exactly like Object B.

OP,
FYI, Unity actually does not read .blend files. When 'loading' .blend files, it opens up Blender in the background, converts it to .fbx and then imports it.

http://docs.unity3d.com/Documentation/Manual/HOWTO-ImportObjectBlender.html

I have been using Blender since 1.7 and am currently also using it at the place I work in combination with Unity. In this case I export my objects directly as .fbx
