I have uploaded the plug-in to export models from sketchup in directx
You must copy it into the plugins folder of sketchup
When you export the model always choose Export textured faces
synchromesh
To change the texture in sketchup you must first create a unique texture in png format.
In the coming days I'll make a tutorial
The software I use? ... Autocad, sketchup, Spazio3D, pconplanner, Kerkythea, wing3d, paint.net.
