There is one pair of files in that list that are usable, the textures are huge so I reduced them which takes the file size down some. The files are:
Acer_Trees_V4_OBJ.zip and Acer_Trees_V4_TEXTURES.zip
There are 3 each of varying ages and poly counts making 9 models so it's a fairly large dl...approx. 170 M for the obj's and 8ish for the textures.
I suspect they are these:
013. 9 models of 3D Trees for other 3D software (OBJ files + textures)
014. 9 models of 3D Trees - TEXTURES PACK ( 7 MB)
