This Could Have Been A Tree Shader

A cute flag shader where you can tweak how visible the rainbow is. Or less visible. Or way less visible. Or-

…anyways.

The rainbow can be made dimmer, weaker, or more vibra-

ANYWAYS

The X can be made thicker.

Much thicker.

Then thicker again.

In fact, a concerning amount of development time was spent investigating just how thick an X can reasonably become before it stops being an X and starts qualifying as urban infrastructure.

I, yes I, the author and developer of this magnificent shader highly and sincerely suggest you try out setting the cross_thickness value to a 100 for maximum visual enjoyment of this shader.

This shader is absolutely PERFECT for projects where the rainbow is everything but a background detail, a disturbance or a the main slogan of a project.

Minor warning I must inform you of: setting X thickness too high may upset certain players and MAY cause them to vioneltly attack something or someone. Keep your family and friends close at own RISK.

    COLOR = vec4(col, 1.0);
