Hello! (bad english.. might made some mistakes)
I really love your mod, but I noticed that it only makes the default ladders 3D.
Can you add support for my mod or can you tell me how can I add support for your mod, so that my custom ladders are also appear in 3D?
Sorry for the late reply. No, this is not possible.
If your custom ladder has the same shape as the default ladder shape then it works. Otherwise the texture might be messed up. Technically a nodebox is created and the texture is applied to the nodebox. If there are invisible pixels where the parts of the nodebox are, then the nodebox parts are not visible.
