Hello, I have a building, and I have just made a ladder model, but my next step is to actually making the ladder climbable. I looked at other objects and they have a LOD called memory, which is a vertice from the bottom of the ladder to the top (Just 2 dots). With the components name of Start1 and End1 In the config I have this: ladders[] = {{"start1", "end1"}}; What am I doing wrong? And what is required next? Cheers.
