We follow the standard procedure when importing rigged assets into Unreal engine. Importing Asset and textures to Unreal engine When we export the crate as an FBX this animation will get exported with it. We move on into the animation work space and create a crate opening animation. The goal is to position the pivot points of the joints so the rotation of the objects is accurate. Using Blenders rigging tools we add an armature and weight paint these to the different objects they are to control. These PBR textures can then be used in game engines such as Unreal engine and the Unity game engine. Texturing in ArmorPaintĪrmorPaint is a physically based texture painting application that lets you texture your models with an easy to use interface. In this course we paint colour and roughness maps for use in the material in both Unreal engine and the Unity game engine. The new texturing space layout in Blender builds on the previous version where you have the ability to texture paint directly onto the mesh. Baking normal maps in Blender involves baking the detail from a high poly object and transferring this to a low poly object using a normal map. When creating game assets one goal is to create low polygon asset for faster rendering in game. Normal maps are a way to add extra detail to an object without using extra geometry. This has benefits when texturing and helps reduce the number of texture maps we need to create. This makes sense with different parts of the mesh will share a similar material. Here are both the top and bottom mesh combined together to maximise use of the UV grid. This can help make full use of the UV space while also reducing the number of textures we need to create and import into the game engine. One of the goals when creating this asset and to get an efficient mesh was to combine any parts of the mesh that could work together. Once you switch layouts into UV editing, Blender automatically switches into edit mode and you can immediately begin the unwrapping process. UV mappingīlenders new work space system makes getting setup much easier and ultimately makes UV mapping a more pleasant task. For subdivision surface modifiers now can be the ideal time to apply these so the UV mapping can begin. Without applying an objects transforms first these modifiers will not give accurate results. This should have been done before modifiers such as the bevel modifiers are added to an object. Doubles can occur by accidental duplication or when objects are combined and overlapping vertices have not been merged.įinally we need to ensure all non uniform transformations have been applied. This involves removing doubled up vertices, ensuring good edge flow and ensuring no tri’s (three sided faces) or Ngons (more than four edges) have been created during modelling. Once the modelling is complete the next stage is to check the mesh and begin the clean up. One of the goals with this asset is to maintain good quad topology and try reduce or eliminate any issues that may arise during UV mapping and texturing. In addition to that to that we try use many of the short cut keys to get the asset modeled quickly and get students into this great habit. The process involves using the great tools available within Blender to model, UV map texture, rig and finally animate so get a game engine ready asset.ĭuring the course we use the tools available in Blender that will help speed up our workflow including loops tools, symmetrize and mirror modifier. In the following post I outline the process we follow in this course. Whether you are creating a game or animation asset in Blender this course will guide you step by step through the process of creating an asset for use in a game engine such as Unreal engine or the Unity game engine.
