OpenGL ES 2.0 render to texture

Question

I\'m trying to render to a texture using OpenGL ES 2.0, but I can\'t seem to make it work.

This is how I proceed:

    struct RenderTexture
    {
             


        

Answer 1

I had exact the same problem as u do. Try to add

glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);

right after glBindTexture(GL_TEXTURE_2D, tex); and black square have to disappear.
