One texture for two differents walls

Sorry for my english.

I have one texture and two walls of very different width.

Actually the texture is small on one wall and big on the other.

Change the 'tiling' parameter affect the two walls.

How can I do for have the texture at the same width and height on the two walls ?

thanks

In your UV map, start off with a projection that introduces as little distortion as possible. Move the lower-left corner of each wall section to (0,0,) in the UV map. Scale if necessary, and then move the walls along the X axis of the UV map, until it looks good.

Or just make a two different materials with different tiling parameters, then you don't have to mess around with modeling programs.
