How to Solve Disappearing 2D Sprite Issue With Shaders in Unity
How to Solve Disappearing 2D Sprite Issue With Shaders in Unity
In this Unity tutorial, we tackle the common problem of 2D sprites disappearing or vanishing when rotated 180 degrees. Many game developers encounter this issue when working on their 2D games, and the solution often lies in understanding Unity shaders and the crucial role of the "Cull Off" setting.
When 2D sprites disappear upon rotation, it is typically because Unity is culling, or not rendering, the back face of the sprite. The Cull Off line in your shader code tells Unity to draw both the front and back faces of your sprites, preventing them from disappearing when rotated. In other words, "Cull Off" stops Unity from culling the back face of your sprite, ensuring that it remains visible even when rotated 180 degrees.
In this video, we walk you through the steps to fix this disappearing sprite problem by modifying your shader code to include "Cull Off." We explain the shader code in detail, showing you exactly how "Cull Off" works to keep your 2D sprites visible from all angles. By the end of this tutorial, you'll have a clear understanding of how to use Unity shaders and the "Cull Off" setting to prevent your 2D sprites from vanishing when rotated.
