Help Glsl Shader and Windows 10

  • Hello

    After searching, tried and tried, here I am desperate, I can not operate the Glsl Shader.

    I do not have the image on the Stage. I read repeatedly GLSL Shader actor tutorial.


     Maybe I did not quite installed isadora?

    Or I'm missing a piece of information?

    I'm by testing on this computer ( Isadora 2.4.5, Windows 10 , Intel(R) Core(TM) i7-4790 cpu 3.60GHz, RAM16.0Go , Systeme 64bits-SSD 223.57 Go SATA III +              NVIDIA GeForce GTX 750 Ti )

    Add to this message a screen capture.

    Someone can give me some advice?

  • Hello,

    Its difficult to judge without looking at all the script…
    From where is coming your code?
    Have you tried with most basic shader, like in the Mark's tutorial?
    For complicated shader, you need a real powerful dedicated graphic card, perhaps it's the problem?
    You have also great sample in the "book of shaders"
    Just be careful to suppress "u_" from some variables, it'd not recognized in the Isadora version of GLSL.
    Hoping you find your way to the joy of illumination.

    Thank you for your answer.
    I have followed to in point the GLSL Shader actor tutorial.
    You can see that on the attached file, even a small shader is not visible on the Stage.
    sorry if my english is not so good.....

    just tried the last code you have posted and it works fine on Mac. I don't have a windows computer so maybe @DusX could try it.
    #ifdef GL_ES
    precision mediump float;
    void main() {
    	gl_FragColor = vec4(1.0,0.0,1.0,1.0);

    Same answer, it works fine on my Mac… Windows is a great black hole for me!

    Maybe its would be best to issue a support request, and I could try to go thru and determine what about your system config is causing the issue.
