Copy vertex paint from a prop to a vehicle sub mesh. Apply and save AnimUV params.

AnimUV_VehicleSubMesh.cs

// Anim UV Scripts
// Create scrolling or multi-frame animations for vehicle sub meshes.

// Run in asset editor and see effects in real time.

// AnimUV Params Mod is not required for using the scripts and saving the asset.
// It's only needed to load the data in-game.

// Animated faces must be vertex painted black! The rest reimains white.
// Shades of gray animate slower, don't use unless you know what you're doing.
// Google how to do vertex color painting in your 3d software of choice!

// for vehicles, vertex colors get generated and overwritten on import
// therefore you need to import the sub mesh as a prop, save, reload
// and then import the vehicle sub mesh, 
// and copy the vertex paint from the prop to the vehicle sub mesh using this script:

var subMesh = 1; // vehicle sub mesh id, starting from 1
var asset2 = PrefabCollection<PropInfo>.FindLoaded("filename.Asset Name_Data"); // CHANGE TO PROP NAME

var asset = ToolsModifierControl.toolController.m_editPrefabInfo as VehicleInfo;
Color[] colors = new Color[asset2.m_mesh.vertices.Length];
for (int i = 0; i < asset2.m_mesh.vertices.Length; i++) colors[i] = asset2.m_mesh.colors[i];
asset.m_subMeshes[subMesh].m_subInfo.m_mesh.colors = colors;

//

// The LODs are not UV animated, they are like regular props.

var reverse = false; // Set to true to reverse the scrolling direction.
