Before I explain my problem, at forehand; these are the programs I use: GM 7 Pro, Sketchup 8 Pro

So I have created this model on sketchup 8 pro and exported it as 'church2.obj'. Of course, I want place this model into my GM-room - I do not have the knowledge to do this so I
followed some tutorials on GMC, but always are there some requiring internet links missing or the tutorial is aimed at later or older versions than GM7 pro.
I can't find the popular importer 'mosaic light' - so hereby would like to know what is the most simple way to import this 'church2.obj' into my GM-room.

Thanks in advance,

Direct importers are quite simple to write for many formats. I've done OBJ and 3DS, so I'll go grab one from the pile.

use this

works fine

With what should I open your Obj loader zip?
Edit: Or even better, can you explain how I should use this?

[bcarroll]

change the extension to .zip (delete the --- characters), then use Winzip, WinRar, 7-Zip, etc...

The file: '3DSTeste.gmk' is a GM pro 8 file, I suppose - so unfortunately I can't open it. Once again: I have GM pro 7.
