That is really amazing for something done in Google Sketchup. I prefer the tidyness of blender as I have tried Sketchup before, and I guess it depends on how you find it?
I am uncomfortable with the controls in Google Sketchup, so perhaps I missed something when using it.
No matter though, Blender converts obj files pretty decently. Imperfect, but I re-convert the file to be used in xdan's Model2N64.
I really like the style this is in... was this part of the Gerudo Fortress's rooms?
That's really interesting that you say that because I, for the life of me, can't figure out blender. Granted, I haven't read or watched any tutorials on it....which I have been meaning to do...but SketchUp is really weird at first but after getting used to it, it's not so bad in my opinion. I can't imagine trying to make something like those hands in bobbo's map though...
