Only 4 additional uniforms possible??

[GabZach]

I have written a simple shader to render simple bricks.
It works, but ...

It seems to me that shaderFrog has a limit on the number of uniforms (besides the predefined ones),
and that limit seems to be 4!
Is that true?

You can find my shader here: https://shaderfrog.com/app/view/5292

It works only because I am hard-coding some of the values of the uniforms at the beginning of main.
But no matter how I order the uniforms at the beginning of the source, I only ever see 4 uniforms in the uniform editor below the source!

Is that ShaderFrog or am I making a mistake?

(Long delayed response, I haven't checked this repo in a long time)

This looks like a bug with the core parser, where it doesn't correctly find the names of uniforms if multiple uniforms are declared on the same line, eg

uniform vec3 BrickColor,
             MortarColor;

The parser will incorrectly detect one uniform here. A quick fix around this bug is breaking them out into individual lines:

uniform vec3 BrickColor,
uniform vec3 MortarColor;

I have written an entirely new GLSL compiler and I'm working on a new Shaderfrog prototype. You can follow my progress if you want. The current ShaderFrog engine is basically deprecated, lots of bugs and not built on solid tech.
