Everytime I textured a extrusion with two textures, 3DC shuts down when selecting the properties. (even after updating the videocard drivers) This is very anoying, because the exporter does not remember atomaticly the shader set in the material slot. (Only when it is visible in the properties, which i can't select )

Is this a error, drivercard problem? (Geforece7300GT, updated drivers)

Can you send me a sample with instructions on how to reproduce the error? To support@amabilis.com.

This is simply said what happened:

-I made a single extrusion as on the image above.
-used two textures on it.
-selected properties to set the shader in the Rail sim material custom field(because he did not remember the shader input of the material field, causin error in Railsim after exporting)
-then I got this error.

Also when I try to change the texture after igs import, I got a Windows error direct after changing the second texture.
