I recently downloaded this addon for 4.2 and I downloaded an SNES .pal file from Lospec but no matter what number I put into the index or range (ie. 4-7), the image only comes out as a single color. I also can't find a way to preview it as while the instructions do state "Preview the render live by opening Camera View in a 3D viewport", when I do that I can only see the default viewport shading.
