Can anyone help?
I'm trying to write a little script to read a txt file of coordinates and convert it to a LW motion file - but I cannot make sense of the *.mot file.

Any help in translating all this info?

Here's the file of a simple Null move of 3 keyframes.

Here's the LightWave Scene file doc:

Scene File Description (http://www.newtek.com/products/lightwave/developer/75lwsdk/docs/filefmts/lwsc.html)

Check out the Envelope section.

Here are the basics. The 9 channels are listed in this order X Position, Y Position, Z Position, Heading, Pitch, Bank, X Scale, Y Scale, Z Scale. The 3 on the line after Envelope tells you the number of keyframes for that channel.

Key -1.1700001 2 0 0 0 0 -0.37000012 -0.18500006 0

The important information after the 'Key' keywords are the Key value (-1.1700001) and the time in seconds (2). The rest of the info you can get from the docs, but it defines the curve parameters at that key.
