What I've learned

Textures

When creating a texture you don't bind it to any particular texture unit

You do it when you actually wanna use it

Texture unit indexing

GL_TEXTURE0 is not 0 And because of that you set sampler2D like that

setInt("texture_sampler", 2); // don't use GL_TEXTURE0 + 2 here!!
glActiveTexture(GL_TEXTURE0 + 2);
glBindTexture(GL_TEXTURE_2D, texture);
