correctly display nif and dds x 2 with opengl

[pvyarashevich]

I had extracted data form *.nif file: vertex, triangles, textures. And successfully displayed it via vispy's opengl example (https://github.com/v...extured_cube.py).

Here texture applied with next code: "gl_FragColor = texture2D(texture, v_texcoord);".

But how to applied two texture files (*.dds and *_n.dds), and how to apply color background (vertex color) for texture (there is no alpha for some parts of items)? Does anyone have experience to display nif mesh with opengl?
