Cinema 4d loses or distorts images from sketchup model

[eddiemoney]

Howdy,

I make models in sketchup and just started importing the collada files into cinema 4d. My goal is to make a simple animation of my model rotating. The model has images applied to it in sketchup and I've eliminated the z-facing issues when I render out of sketchup but c4d does not behave. When I import the .dae into c4d, it looks like there is z-fighting going on... When it rotates, the images get choppy and even disappear.

Here's a link to a vid so you can see what is happening: http://youtu.be/CB5UIUharFo

Some parts of the model go away completely, which I don't understand either... here's a shot of that: http://youtu.be/9cznLw66Xm4

Any help would be appreciated.

Thanks

There are three things I can think of (if there is really no Z-fighting due to overlapping faces in SU):

• there are also group/component materials in the model. They should be deleted and materials only applied to the faces.
• there are different materials applied on back faces. They should also be deleted and the model exported (under the collada export options) without double sided materials.
• I forget the third but also make sure that your faces are oriented correctly (i.e. no back faces showing in monochrome mode).
