As someone who has acquired quite a bit of PS knowledge in the last few months I can recognise the amount of expertise and time and effort spent in creating this awesome package. DPR truly deserves a medal for what he has done.
And what makes this extra special is that he is providing a tool free that will enhance courses by leaps and bounds. having been involved in 3D golf creation programmes before I can say that 3D objects (or lack thereof) has been an achillies heal for most of them in that a few objects have been provided at the outset and never, or rarely added to, things got pretty boring pretty quickly.
A truly talented and generous person DPR is to be sure.
