Hi!
I wonder if anybody has a good idea. I saved a file from Sketchup 7 as .DAE. Imported this file to Blender, and exported it as a .3DS file.
I imported this file into Poser, looks ok until I render it. Seems very broken?  A lot of sqares an triangles in different colors. How can I fix it?

Was there a particular reason why you chose 3DS over obj? If you have a look at Poser's geometries folder, you'll find that everything (mesh) has been saved as obj. I suggest you export to that format instead.

Thanks for your answer!
Only reason to use 3DS was to check the file in Max before imorting it to Poser. I will try your suggestion, hope it works. I think the problem is related to "backfacing polygons" or something? Because the mesh looks ok in both Blender and Max, it´s the rendering in Poser that screws up the model.

Try checking Normals forward on the Root node in the material room.

 While Poser can import 3DS files, it doesn't really like them much.

I'd try exporting it as an obj and see if the problem persists - Max will import obj files just fine, too if you want to check it first :) 

Thanks for answers!

I have tried the following:

Saving the file from Sketchup as a .DAE-file.
Imported DAE to Blender, looks ok,
Exported file as .OBJ, looks ok but renders bad.
Opened .OBJ in poser, looks ok, but renders just like the 3DS-file did.
Tried "normals forward", same result.

Seems like a problem with the .DAE-file, the other apps don´t understand what´s up and down on the mesh-surfaces?
Anything else I can try? (I´m not very good with meshes) :-)
