How to Merge BIP Files Without Position Jumps in 3ds Max

The BIP Files Puzzle: How to Avoid Annoying Jumps 🕺➡️🤸

What a bouncy little problem you've run into! When BIP files decide to play hide-and-seek on the Z-axis, the animation looks more like a 90s video game than professional work. Let's bring order to this coordinate chaos.

The Root of the Problem

This happens because each BIP file saves:

• Its own initial position in world space
• The Biped's orientation at export
• The specific figure adjustments

"Merging BIP animations is like coordinating a ballet: everyone must start on the same stage"

Step-by-Step Solution

1. Before importing:
   • Activate Figure Mode on your Biped
   • Place it at the origin (0,0,0)
2. When importing each BIP:
   • Use Load File (not Paste)
   • Check Convert from Max in options
   • Select Load Buffer Position
3. In Motion Mixer:
   • Add a Transition Track between animations
   • Adjust the blend curve to smooth jumps

Professional Tricks

• "T" Tool in Motion Flow to align transitions
• Biped Key Info to manually edit key positions
• Relocation Script to normalize all animations

If all else fails, the nuclear method is:

1. Export each animation as FBX
2. Reimport with normalized position settings
3. Convert back to BIP

Remember: patience is key. With these adjustments, your Biped will stop jumping like a kangaroo and move with the elegance of a swan (or at least, of a well-paid animator). Time to animate! 🎬
