This function replaces the given model in the given model ID with the DFF file passed. This function supports vehicles and objects at the moment.
This function replaces the given model ID with the model contained in a DFF file loaded by [[engineLoadDFF]]. This function supports [[vehicle|vehicles]], [[object|objects]], [[ped|peds]] and [[player|players]] but not CJ clothing and body parts.


As of 1.1.1 This supports Ped and Weapon models. For replace weapon models you can't use weapon ID's, you should use object ID's. All weapon model ID's here: [[Weapons]].
{{Deprecated feature|3.0111|1.1.1|This function does not support ped and weapon models.}}


Note: Due to a bug, when replacing models with built in collisions (i.e. vehicles), the collision may not get replaced correctly. The current work around is to load the dff again and do another replace after a short delay.
To replace weapon models you must use their object IDs, not weapon IDs. There is a weapon model list available at [[weapons]].
{{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.
* Default GTA map objects behave inconsistently when using this function on them. If you want to replace models in the original GTA map, use one of the [[EngineReplaceModel notes|methods shown here]].
* A raw data DFF element can only be used once, because the underlying memory for the model is released after replacement.
* If the replacement model is broken and the original model is not loaded/streamed-in at the time of replacement, this function will succeed and you won't see any error message, neither when the model replacement fails once the original model starts to load/stream-in.}}

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.

[[{{{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.
  • Default GTA map objects behave inconsistently when using this function on them. If you want to replace models in the original GTA map, use one of the methods shown here.
  • A raw data DFF element can only be used once, because the underlying memory for the model is released after replacement.
  • If the replacement model is broken and the original model is not loaded/streamed-in at the time of replacement, this function will succeed and you won't see any error message, neither when the model replacement fails once the original model starts to load/stream-in.

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.

Example

Client

This example allows you to replace single or many models (with ability to toggle TXD filtering/DFF alpha transparency) - by using table. Do not forget to add those file paths to meta.xml 

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
addEventHandler("onClientResourceStart", resourceRoot, onClientResourceStartReplaceModels)
