Uniforms

The Uniforms panel edits the values declared in the custom shaders of the material. It appears when the selected material uses a custom shader.

Each uniform becomes a field according to its type: float uses a slider, vec2, vec3 and vec4 use numeric fields, and colors use a color picker.

The refresh button reads the uniform declarations of the vertex and fragment shaders again. Uniforms added to the code show up in the panel and the removed ones stop appearing.
