Import/Export between ZBrush and 3Ds Max
This small but significant topic is so important that it deserves it’s own post. Importing and exporting in ZBrush from other programs has many problems that must be solved to make the importing and exporting seamless between both programs. ZBrush’s Import export tab in Preferences controls the parameters and functions ZBrush applies to importing and exporting. The settings are set up to account for almost every possible arrangement to make your workflow seamless.
When importing and exporting between ZBrush and 3Ds Max with default settings, you will always find that the models are in the wrong orientation, in one of the programs. This is due to that ZBrush and 3Ds Max uses the XYZ axis in a different order, like Maya differs from 3Ds Max’s XYZ. I’ve found that the the iFlipY, iFlipZ, eFlipY and eFlipZ must be on in order to accommodate the XYZ arrangement between ZBrush and 3Ds Max.
iFlipX,Y,Z means that on model import; X, Y and/or Z axis will be flipped.eFlipX,Y,Z means that on model import; X, Y and/or Z axis will be flipped. There are a ton of other buttons in the Import export tab that changes other things like flipping normal on import or export and so on.
