Image 13: The Roughness Map controller setup. Don’t forget to add the created parameters to the Roughness group. After that, connect the nodes via the Lerp node as shown in the image below. Roughness Map Controllerįor the Roughness Map controller setup, create two ScalarParameter nodes and name them “Roughness Min” and “Roughness Max.” You can define a default value using the menu on the left. Image 12: The Normal Map controller setup. To create a Normal Intensity parameter, search for the ScalarParameter node and name it “Normal Intensity.” Don’t forget the add it to the Normal group we made earlier. Then connect them as shown in the image below. Normal Map ControllerĬreate two Multiply nodes and two Append nodes by right-clicking and using the search function. Image 11: Use groups to organize parameters. We will use groups to organize other parameters we’ll create - for instance, “Normal Intensity.” Select every material you created and give them a group name. To keep your material parameters organized, you can also define a group for each map type if you want. Image 10: Copy the DiffuseMap mode five times. Select the DiffuseMap node and copy it five times using the Ctrl-D keyboard shortcut, and change the names to “Normal Map,” “Height Map,” “Roughness Map,” “Metallic Map,” and “AO Map.” Right-click on the TextureSample node, select Convert To Parameter, and name it “Diffuse Map.” That will help us to change our texture image for other materials. This will automatically create the TextureSample node. You can also use a shortcut: press T on the keyboard and click on the empty area. On the empty screen, right-click and search for TextureSample. Image 8: M_MasterMaterial’s material graph. We will create our basic master material here. That will open the node-based material-setup window. Name it “M_MasterMaterial.”ĭouble-click on M_MasterMaterial. Image 7: Return to the Materials folder and create a material. Right-click on the content browser to create a material. Image 6: Drag and drop your textures into the Textures folder.Īfter uploading is completed, return to the Materials folder. Image 5: Right-click on the content browser to create a new folder. Right-click on the content browser, create a new folder, and name it “Materials.” Open that Materials folder and create another folder named “Textures.” Select all the textures that we prepared before, and drag them into the Textures folder. Before creating a master material, let’s create a few folders. There are plenty of master material types, but we will create a basic one that let us adjust PBR map intensities. We are using master materials to adjust different materials using the same controllers. In Unreal Engine, master materials are the parents of material instances. Image 4: Unreal Engine 5’s Create A Project menu Step 3: Create a Master Material That will not change the material setup at all. I will continue with the Film/Video Live Event section’s blank project. Open Unreal Engine 5 and create a blank project based on your need. Note: You can use Bulk Rename Utility to change names easily. Image 3: Asset names that have been changed based on Unreal Engine’s Recommended Asset Naming Conventions. For diffuse or color maps, the suffix _D. For ambient occlusion maps, the suffix _AO. Let’s make them conform to Unreal Engine’s naming standard! (If you want, you can pass this section.)įor all textures, we will use the prefix T_. Image 2: Downloaded assets without name changes. I downloaded paving stone and wood shingle materials from my library. Login to your Poly account and download the assets you want.Įxtract them from the. Let’s get started! Step 1: Download and Prepare Your Assets We’ll use Unreal Engine’s Recommended Asset Naming Conventions to keep everything organized. Our master material will let us change map intensities to adjust height, normal, and roughness power. In this tutorial, I’ll show you how to create a master material and material instances in Unreal Engine 5. □ Textures used: Poly Game Texture Collection, Poly Unreal Texture Collection
