In UE4, LODs are controlled by object screen size, not camera distance. Then, in the LOD Settings Asset you can set the screen size of the object to activate each LOD.
To create one, simply click the “Generate Asset” button in the LOD Settings roll down of your Skeletal Mesh, as you see below. You can configure how the LOD switching happens if you create an LOD Settings Asset. If, for example, the character will never show up close to the camera (if it’s a “filler character” for your crowd), you only need to generate the LODs. However, as I said before, you will need this avatar depending on your specific needs. This avatar features the full quality skin material and textures, as you can see in the image. If you checked the “Keep Original Avatar” checkbox, your LOD0 will be the original avatar. Another thing you can do to test the LOD is zoom out in the viewport, so you can see how the model changes as you move backwards. The image below shows the third LOD (the original setting is “Auto”). Then, you import your exported character into UE4, and check the “Import Mesh LODs” box.Īfter the model is imported, you get your Skeletal Mesh with the LODs you exported (the number of LODs obviously is defined by the number of LODs you exported from CC3). First, you need to export your character from CC3 using the InstaLOD settings, and generating the amount of LODs you want (the “Keep Original Avatar” is optional, depending on what you want to do). Using LODs in UE4 is pretty easy (actually, a lot easier than Unity). The issue is this: not only it’s a waste of resources to have a very high-resolution model far from the camera (since you can’t see the detail) engines can have a hard time drawing those because triangles are perceived to be so close together the engine wastes resources to draw them. While Character Creator 3 produces amazingly high quality for video games by default, you still need to generate lower resolution models for some situations, like when your character is far from the camera.
