How can I handle 2 texture in fragment shader?
There’s a good example here…

In a nutshell you assign as many as you need in the shaders, within your GPU’s specs.
uniform sampler2D tex1, tex2, tex3 etc…
Setup the textures in OpenGL as normal and then assign their texture ID to them when you setup the shader with single Integer Uniforms with the same name as you gave them in the shader.
