this question is within the scope of the regular poser forum. there are some very helpful users there who can supply a multitude of links to describe basic poser operations and functions. the materials functions in poser 7 are very similar to P6, and it's likely any mt5 collection made in p7 will work in p5/6, altho test it first by retaining P6 in a separate folder, along with its runtime. do not delete P6 unless absolutely necessary.
