Swapping a Part Between Two Cars

A part swap is more than copying a model file. If you skip the ambient occlusion path or the material indices, the part will load looking wrong.

The quick route

The tool author notes that you often don't need to touch the AO path manually:

Press the + button in the Carbin editor to add a model from a modelbin or carbin. If you choose a carbin as the source, it sets the AO path, materials, and everything else for you.

Try this first — the manual procedure below is only needed when it doesn't apply.

The manual route

1. Open the carbin for both cars. The carbin lives in the main directory of the car folder.
2. In the donor car, search the model list for the part you want, right-click it, and choose change AO path. Copy that path.
3. Switch to the target car and set the AO texture for the corresponding part to the copied path.

Sync the material indices

If the part uses car paint, it will not render correctly until the materials are synced:

1. Scroll down in the part's entry to the Material Indices section.
2. Click the button in the top right of that section and select the part you replaced. This syncs the materials.
3. For the carpaint entry, click the dropdown next to it and select the part (for example, the wing).

This step can be done last, after the AO path is set.

Paint groups

Switching a material to car paint is not sufficient on its own. For a part to be paintable in-game it must be assigned a paint group.

Paint groups are assigned in the Carbin editor, in the same Material Indices section: find the part, and choose from the list of paint groups on the right. If you performed a material swap, sync it first using the top-right button.
