How To Fix Texture Colored Pink In Blender

Problem

When I open Blender file, the textured model is rendered with pink single-colored texture. How can I fix it?

Environment

Blender 2.8.3(LTS)
Windows10

Cause

Pink means missing texture. Blender couldn’t find the specified texture.

Solution

However, this sometimes occurred when the texture is just overwritten. In that case, I fixed by following steps below.

1. Disconnect Image Texture Node from Base Color socket of Shader Node.

2. Reset texture in Image Texture Node on Node Editor

3. Reconnect Nodes
