• removed PI definition as it is now built-in

addons/shaderV/rgba/bloom.gd
addons/shaderV/tools/random/randomGoldNoiseFloat.gd

• added a semicolon in the generated code

addons/shaderV/rgba/generate_shapes/scanLinesSharp.gd addons/shaderV/rgba/generate_shapes/stripesRandom.gd

Visual shaders

Sobel Edge

• connected new white constant to output

Color Correction Adjustment

• added gradient as parameter

Hash Random Vector 2D and Vector2 Compose

Thank you for this! saved me some work though i had another problem. I tried using worley3d with the default values:

  151 | void fragment() {
  152 |  float n_out12p0;
  153 |  float n_out12p1;
  154 | 
  155 |  vec3 n_in12p1 = vec3(0.00000, 0.00000, 0.00000);
  156 |  int n_in12p2 = 5;
  157 |  int n_in12p3 = 1;
  158 |  int n_in12p4 = 0;
  159 |  {
E 160->  vec2 n_out12p0n_out12p1 = _cellular3dNoiseFunc(vec3((UV.xy+n_in12p1.xy)*n_in12p2, n_in12p4), min(max(n_in12p3, 0.0), 1.0));
  161 |  n_out12p0 = n_out12p0n_out12p1.x;
  162 |  n_out12p1 = n_out12p0n_out12p1.y;
  163 |  }
  164 | 
  165 | 
  166 |  COLOR.rgb = vec3(n_out12p0);
  167 | }
  168 | 
  :160 - Invalid arguments to operator '*': 'vec2, int'.
  Shader compilation failed.

I could stop the error from appearing by changing the init func default values to floats.:

func _init():
	set_input_port_default_value(1, Vector3(0.0, 0.0, 0.0))
	set_input_port_default_value(2, 5.0)
	set_input_port_default_value(3, 1.0)
	set_input_port_default_value(4, 0.0)

looking through the other files it seemed like a random choosing between floats and ints as defaults. Is there a reason someone would want to choose an int as a defaultvalue for a VisualShaderNode.PORT_TYPE_SCALAR? or is it just something i happen to be the first one to notice?

@thomasgauthier thanks a lot!
Could you please check error @Ludmuterol mentioned? Maybe it will be better to change every default port to float which supposed to be float. I didn't face this problem before so didn't care about this - maybe in 4.0 something was changed in Godot.
Could you also check if it is possible to change .gdshader to .gdshaderinc and change global code section to inclusion of .gdshaderinc file? But if it will break something or take a lot of time I think it could be left as it is now.

I also had problems with scalar input being treated as ints instead of floats. Changing all relevant inputs to floats explicitly like @Ludmuterol described probably would fix it. I can try this.

@arkology I can do the .gdshaderinc change over the weeked. I'll post updates here.

[thomasgauthier]

Just got to this now. 6f5cabf has the .gdshaderinc change and the float problem fixed

[arkology]

@thomasgauthier thanks! I'll test it at the weekend and merge into master

[arkology]

I quickly ran through the changes and overall everything looks great! If something is wrong, it can be fixed later, but right now I think it's ready for merge🎉

Thanks!
