Curved UI

This tutorial introduces how to use FairyGUI to make curved UI. The principle is to capture the target interface onto a RenderTexture, and then paste this Texture onto a surface model. Click detection is done using MeshCollider. It can also be seen from this principle that FairyGUI not only supports curved UI, but also any shape UI, as long as the corresponding model is provided.

Making curved UI

First put the prepared surface model into the scene:

Hanging a GameObject on the modelUIPainterComponent, the “Mesh Collider” component and “Mesh Renderer” component should be automatically added at this time.

The settings of UIPainter and UIPanel are very similar. After setting “Package Name” and “Component Name”, the corresponding UI can be displayed on the surface!

There should be a shader selected for the material. If you don’t need special effects, select “FairyGUI/Image”. If you need lighting and other needs, you can also choose other shaders. (If there is no material, create a new material yourself).

When using curved UI for VR, you need to pay attention to both Stage Camera and Capture Camera.NoFollow the eye movement. Generally speaking, using a higher version of the FairyGUI SDK (if using a dll version, be sure to match the version of Unity), FairyGUI will be set automatically. If display problems occur, check that the camera settings are correct.

UIPainter

When using a curved UI, you need to capture the UI into a texture, so you need to define two layers, VUI and Hidden VUI, otherwise a warning will appear. These two layers can be freely defined to the unused layer number, but please note that the Culling Mask of all camerasNot chooseThese two layers. In addition, the Capture Camera object will automatically appear in the runtime scene. This is normal and need not be bothered.
