Puybaret, THAT'S PERFECT!!!... I found another thread that had semi-transparent png files to download, applied them as texture, and it works FANTASTIC!!!!!Instead of playing with "d" MTL parameter, maybe you could try to use a half transparent texture. You could also try change the renderer quality to the highest level which render shiny objects with a more glossy effect.
Thanks sooooooooo much for the great tip!!!!!!
