Please note that DrawMaterialToRenderTarget will not work in Construction scripts outside of the UE4 editor which means if you are trying to do this at runtime it will not work.ДЇrom this menu locate the Bake event that was created by inputting Bake into the search box and once found, click on it to add it to the graph and then connect the output of the Construction Script to the input on the Bake node.ДЇinally, press the Compile and Save buttons to compile and save your Blueprint. Now, click on the Construction Script tab and drag off the Construction Script node to display the Executable actions menu. Once that is completed, do the same for the Material section, selecting RT_Material_00. Next, on the Draw Material to Render Target node, load the render target that was created previously into the Texture Render Target slot by clicking on the small white triangle next to Select Asset, and then from the list, find the render target RT_00 and select it by clicking on it. Then, connect it's output to the input of the Draw Material to Render Target node.

Select the Custom Event node and press F2 so that you can rename the Custom Event node to Bake. Right-click in the Content Browser and from the menu that is displayed in the Create Basic Asset section, select the Blueprint option to create a new Blueprint.ДЇrom the Pick Parent Class window, select the Actor class and then name the Blueprint BP_Texture_Creator.Дouble-click on the BP_Texture_Creator Blueprint to open it up and once opened, click on the Event Graph tab to open up the Event Graph.ДЄdd the following Blueprint nodes to the Event Graph: To create a Blueprint that will work with both render targets and Materials, you will need to do the following. In the following section, we will go over how to setup all of the various parts of the Height Field Painter Blueprint. With the render targets and needed Materials setup and ready to use, it is now time to bring everything together using a Blueprint. Name the newly created render target RT_00 and when completed, the Content Browser should now look like the following image: From the menu that is displayed, locate the Create Advanced Asset section.ДЇrom the Create Advanced Assets menu, mouseover the Materials & Textures section and from the asset list that is displayed, select the Render Target option. Open up the UE4 Editor and then right-click inside of the Content Browser. Once the required Material Expression nodes have been added to the Material Graph, connect the nodes so that they match the image below, pressing the Apply button when completed to compile the Material. With RT_Material_00 open in the Material Editor, add the following Material Expression nodes to the Material Graph. Name the Material RT_Material_00 and then double-click on the material to open it up in the Material Editor. Right-click in the Content Browser and from the Create Basic Asset section, select the Material option to create a new Material. In this section we will go over how to create and setup the required assets so you can create Textures using Blueprints and Render Targets. With the level now created and saved in the next section we will go over creating and setting up the required assets. Once that has happened, save the level by clicking on the Save button on the Main Toolbar, naming it BlueprintTextureCreation.

To create a new Empty Level inside of UE4, you will need to do the following:ДЇrom the Main Toolbar, go to File > New Level.ДЇrom the New Level window that is displayed, click on the Empty Level option.ДЄfter clicking on the Empty Level option, UE4 will load a new level that has nothing inside of it. In the following How - To, we will take a look at how you can use Blueprints and render targets to create Textures for your UE4 projects by first creating a new empty level in a UE4 project and then creating and setting up the render targets for use.Д«efore we get started, there are a couple assets that we'll need to create as part of our project setup.Д¬reating a new Empty Level to place your Texture creation Blueprint in will make things easier to manage, ensuring that nothing else is affecting your Texture creation process. While authoring content in this manner can give you amazing results, there are some instances where having the ability to create content like this inside of UE4 would be helpful. When creating Textures for your Unreal Engine 4 (UE4) project, you will generally need to use an external 2D painting program like Adobe Photoshop or GIMP.
