*Huff*
A few hours, seven different types of (successfully but nonetheless incorrectly installed) birch tree, twelve different types of awkward and matless pine trees, and forty-eight downloads, I am clueless.
I gave up on the horse mesh because I couldn't figure it out at the time, but after my minor success with the birch I will try again and perhaps be more successful.
I downloaded the BirchA-D file meshes, and downloaded the D, N, S, and leaf file associated...Goodness the wombat filing system is chaos. I had to edit the DNS files to make them square. I tried using the OGRE text that was available for download with them but I had no clue where it was supposed to go and it crashed feralhearts when I had it so I just ignored it. Then I kind of played with it and put it in the code when I was putting the .pngs into the tree file so I could use them (like how you put the rocktex7.png into the rockMat material file) and altered the file path and yatayata tons of experimenting yatayata...lol probably just confused you....It was a crazy and jumpthroughhoops process to get a partial result. I still can't figure out the pine tree, and I can't figure out what makes it so different from the birch tree that it won't work. x.x
