Exporting FBX files in 3ds Max
If you use normal or parallax mapping, make sure to export Tangents and Binormals. Those can still be generated
by the importer, but exporting them here will avoid generating wrong tangents and allow fine-tuning.
If you also want to save animation data, make sure to check the Animation box. In our case, only the Dragon
model uses animation.
When animation data is used, select Bake Animation to make sure your importer does not have to calculate all
animation matrices, which could slow down importing and rendering. If you like to use key frames and bake matrices
yourself, turn the bake option off. Also make sure your start and end time frame is set up correctly.
The Delta Engine uses Z up as the up axis. Make sure to use the same setting here (it's the default for 3ds Max anyway).
Finally, select the latest FBX version (2014.1) and use the Binary format. The text format is also useful if you need
to diagnose FBX import issues.
