Mike posted a few teasers of PG2 and for whatever reason the bunker caught my attention. I've fiddled in the past with bunker lip adjustments to make something appear more "dug out" from a mesh standpoint but wanted to show a "faux" shadow that can be added by utilizing the "Pot" layer.
Mike's teaser
Typical in game with PG1 (bunker at Muirfield Village)
Small tweak to give more ledged appearance to the bunker lip
Could probably shorten the Blend on the "Pot" layer a smidge as I'm exaggerating that shadow with it. Layers library settings for the above effect. It's casting an 8 cm shadow and should probably be 3-4 cm. You also have to create a layer that will be your shadow used for the "Pot" dropdown. Mine is a clone of my bunker layer just set to a darker value using "Main Color"
I have no idea why I still fiddle with these things...
