Having an issue with the textures being white
ditto
Easy fix - Open the soybean.i3d and double check your file paths are pointing to the correct textures
They are, still not working
In the files section of the soybean.i3d, change the 8 files with .dds file extensions to .png. This worked for me in addition to making sure file paths were correct. Big thanks to Antler22 for his beautiful work!
