Materials in imported scene

[kubabuk]

Is it a shortcoming of XSI or am I missing something...? When I import complex scene (in obj format) into XSI every object gets it's own material.
For example: all walls previously (I'm importing from Maya) had one brick material assigned and after importing to XSI every wall now has its own one (with the same settings as original). I know that in XSI I can group all walls and assign one material to the new group - but when scene is complex selecting thousands of objects and grouping them is rather a tedius and frustrating hobby... Please help! Do you know any workaround?

thanks in advance...

When I import OBJs, I instantly mass delete all the clusters materials from it. Then the entire model has just one material on it. (The scene material.)

Thanks for such a fast reply!
So there is no way to work with these imported materials - I mean to select all objects with the same material attributes (with the same texture) group them and assign a new material to the group?
I'm not familiar with the XSI scripting language - what do you think about putting this task into script? is it possible?
