Post Body

i don't even know why this is happening when try to set a rotation matrix to the transform uniform in my shader nothing is drawing but when i set gl_position to just the vertex position my triangle draws

drawing code:

            GLHelper.Clear();
            GL.UseProgram(shader.Program);

            GL.ProgramUniformMatrix4(shader.Program, 20, false, ref proj);

            mesh.Draw();

            SwapBuffers();

shader code:

#version 440 core

layout (location = 0) in vec3 position;
layout(location = 1) in vec4 color;
layout (location = 20) uniform  mat4 transform;
uniform float f;

out vec4 fragcolor;

void main(void)
{
    gl_Position = transform * vec4(position,1.0);

    fragcolor = color;
}
