I'm new to create custom content, so I'm following a tutorial for creating objects. In the step of changing the default pattern, I downloaded the newest version of TT3, and tried to pick pattern for pattern C. However, the poped up Complate Picker was blank, without any patterns to choose. I thought maybe the reason is that TT3 doesn't recognize my game folder automatically as the author said in description, because my game folder is in other language. Then I tried to click Help and click Game folder, but it just poped up another blank window. I even tried redownloading TT3, but nothing changed. Thanks for any help!

edit: I have downloaded the pattern preview folder created by the author.

edit: I tried to make TT3 to create pattern preview folder, but it said done immediately, which should have taken a long time as the author said. And it actually did not make any folder. I really doubt TT3 doesn't recognize my game folder, but I don't know how to change the setting by myself.
