Then select the "Door" group from the pulldown, and remove the "D_Door" group from it. {Image 6}
(You may have to go between the "Door" group & "D_Door" group a few times to get all of the problem normals into the "Door" group. Feel free to move your camera around to get the best view of the area you are working on. Don't worry if you add polygons that should not be in the selection; because they are easily removed using the "-" tool.)

Once you have all the problem polygons in the "Door" group & removed from the "D_Door" group, select the "Door" group & click "Reverse Group Normals". {Image 7}

By using the above technique I corrected the problem polygons in the right side skirt.

Here is a look at the model with the now corrected normals. {Image 8}

Now time for some material shaders:

Switch to the Material Room, and make adjustments to the material zones to suit your tastes.
This model's tires & wheels share a material zone (The material zone is named "Mag"){Image 9}; so I will assign a new material to the tires.

Activate the Grouping Tool, and select the tire's group; then click Assign Material.
Type a new material name in the dialog that appears (I chose "Tires"), and you'll have a new material zone to work with. {Image 10}

This model has a separate group for the rear tires; so I selected that group ("Tire01"), an again clicked Assign Material; but this time I typed the same material that I chose for the front tires ("Tires" - be careful not to change the spelling or you will have a new material zone for the rear tires).

(I chose to assign materials for the Headlight covers also.)


Now we have a new very low-poly car for use in Poser. {Rx7 Final.jpg}

NOTES:

1.) I normally would not have chosen this model for use in Poser renders; because it needs some work that can only be accomplished in a modeling application (Subdividing, Smoothing, Taillights, Interior, etc.). I probably would have just imported the wheels & tires to Poser & saved them to the Props Library for use on other autos.

2.) It is usually easier to make the normals consistent in a modeling application; but there is no guarantee that the model will import into Poser with the corrected normals in place. (I've had some work well, and others that did not. When the normals are corrected in Poser, then I know they will work correctly in Poser.)

3.) It is usually easier to assign materials & material zones in a modeling application; but the values will usually need to be adjusted in Poser.

4.) Poser's Grouping Tool is not intuitive. It can be very frustrating & confusing to look at. I have learned to move the cursor away from the preview window, and let the green lines disappear in between selections; this seems to be the best way to be sure that you are indeed selecting the polygons that you want to be selecting. (This is the primary reason that I said above that it is usually easier to use a modeling application to do these tasks.)

Next, we will definitely take a look at some things to keep in mind when importing "High polygon" or "High detail" models into Poser.
