Hehe...well, the readme.txt explains in general what I did in this mod.
...and you can feel free to deconstruct my structures and make things out of the panels.
Every part of the panels used to be the log (tree_leafy_fallentrunk), including the collision model.
Within the collision model meta there are vertices, which I changed so that the collision model would be 5x longer along the Y axis. There are also a couple other numbers that I had to change in the collision model meta to get it to stretch to that size.
If you want to see what I did just use HMTv3 to extract the collision model meta for the tree_leafy_fallentrunk (from a clean cache file) & the collision model meta for the panel_sm_thick_metal (from a cache with my mod applied).
Then you can open them both up in a hex editor and compare them to see what I changed.
I recommend Hex Workshop because it actually has a "Compare" function.
