AgentSmith : okay..anyway, thank you for your reply Hi comet166: could u please post the original displace map for me?? thanks~~ :) Ang25: it seems that susan kitchens didn't use Bryce 5 to create hoodoos, neither install the patch.. so I guess there must be some way can erase the edge.. and if u also brought the real world bryce 4, maybe u could write peachpit a letter for help about the missing files, 'cause till now, they still not reply my request..
