If I’m not mistaken that model comes from 3D warehouse. It looked like a SketchUp issue… Lots of people who are great modeler don’t understand the flipped normals in SU.
Open the model up in SU… Go to View> Face Style> Monochrome… You’ll see that the parts of your model that are Blueish-purple are the same parts that are reversed in Poser.
There are two ways of fixing this…. The best is to flip them manually, You will have to choose- View> Hidden Geometry and then go into the various groups that make up the model and flip the normals to the WHITE side facing out… (the problem is the part may not be “painted” on the other side)... you flip the normals by Choosing- Edit> Face (or Surfaces)> Reverse faces.
There is a script that tries to figure out what faces are flipped improperly and tries to fix it… it may be OrientFaces.rb, but I forget… Go to SketchUcation and look around in the plugins index at the plugins forum…
I have to run now, I’ll try and check back tonight and see if there is something better out there… Good luck.
I do alot of Sketchup modeling. There are tons of models with this problem. Beginners especially. They think,click, ooooo color and go with that. It works fine for SU but it won’t work when exporting. There are two sides like you said, a white one and a bluish one. Each will take a color or texture. The side that is white will dominate when exported. You also will get a surface called “Font” which will always be white. Sometimes the entire model. These are the flipped normals with the wrong side (bluish) one textured or colored. Will stay white.
One way to resolve this is to use grouping. If you make a flat plane, select it, go to edit, make group. The entire plane will then select with edges. Now texture or color it and it will export with that color or texture on both sides everytime. I group everything. Make a room, make a wall plane, cut your window or door way, now group it. Now pull out the wall for thickness. Now texture it all one color, OR, go to edit, edit group, open the group up and color inside wall part, and use a brick texture on the outside wall part. click the group off and it will hold the color and bricks in place. It can get complicated, but gets easy after you learn how to work with groups…also you can group something, like a table leg, then go to edit, copy, paste into place, and it will duplicate the leg on top of the other one, then just use the arrows on your keyboard to move them side to side or up and down. This makes a precise placement. I do this for tires on cars, you can even flip the tire in edit also.
The person who made this car must have either converted it from a .3ds file or .obj file and just didn’t know about grouping correctly. I have made hundreds of models in SU and never had a single complaint on import of the .obj files from any program user. This is the key…grouping!
