[[{{{image}}}\|link=\|]]	Note: Please note the loading order that is used in the examples as other orders can cause collisions, textures or the DFF not to load due to technical limitations

This function replaces the given model ID with the model contained in a DFF file loaded by engineLoadDFF. This function supports vehicles, objects, peds and players but not CJ clothing and body parts.

To replace weapon models you must use their object IDs, not weapon IDs. There is a weapon model list available at weapons.

Syntax

bool engineReplaceModel ( dff theModel, int modelID [, bool alphaTransparency = false ] )

OOP Syntax Help! I don't understand this!

Method: dff:replace(...)

Required Arguments

theModel: The model to replace the given model ID with
modelID: The model it to replace the model of

Optional Arguments

alphaTransparency: Set to true if model uses semi-transparent textures, e.g. windows. This will ensure other objects behind the semi-transparent textures are rendered correctly. (Can slightly impact performance, so only set when required)

Returns

Returns true if the model was successfully replaced, false if it failed for some reason, ie. the DFF or the model ID is not valid.

Client

This example allows you to replace single or many models (with ability to toggle TXD filtering/DFF alpha transparency).

function onClientResourceStartReplaceModels()
	local modelsToReplace = {
		{ -- replace object
			colFile = "object.col",
			txdFile = "object.txd",
			dffFile = "object.dff",
			modelID = 1337,
			alphaTransparency = false,
			filteringEnabled = true,
		},
		{ -- replace vehicle
			colFile = false, -- if .col is not present set to false/nil
			txdFile = "vehicle.txd",
			dffFile = "vehicle.dff",
			modelID = 434,
			alphaTransparency = false,
			filteringEnabled = true,
		},
	}

	for assetID = 1, #modelsToReplace do
		local modelData = modelsToReplace[assetID]
		local modelCol = modelData.colFile
		local modelTxd = modelData.txdFile
		local modelDff = modelData.dffFile
		local modelID = modelData.modelID

		if modelCol then
			local colData = engineLoadCOL(modelCol)

			if colData then
				engineReplaceCOL(colData, modelID)
			end
		end

		if modelTxd then
			local filteringEnabled = modelData.filteringEnabled
			local txdData = engineLoadTXD(modelTxd, filteringEnabled)

			if txdData then
				engineImportTXD(txdData, modelID)
			end
		end

		if modelDff then
			local dffData = engineLoadDFF(modelDff)

			if dffData then
				local alphaTransparency = modelData.alphaTransparency
				
				engineReplaceModel(dffData, modelID, alphaTransparency)
			end
		end
	end
end
