It is not my intention to be destructive or hostile, and I feel that my complaint/ criticism is a valid one. Most of the texture services I see being offered so far that claim to be PBR truthfully are not, including one, and suggesting that a prospective PBR content service conduct due diligence in researching and understanding what PBR means so that they may effectively apply that knowledge to their offerings before releasing them to the community ‘is’ constructive from my perspective.
