How can I use a new character?

Hello,

Various things including the skeleton structure are somewhat hard-coded so be careful if you are using your own data and own network weights and want to update them.

Hence it is highly recommended that you retrain the model with your specific requirements.
However you have to do proper pre-processing before doing the same.

You have to build the database of terrain patches which are later
fitted to the motion. For this simply run the following.

python generate_patches.py

This will sample thousands of patches from the heightmaps found in
data/heightmaps and store them in a database called patches.npz. This
should take a good few minutes so be patient.

Now you can begin the process of preprocessing the animation data - converting
it into the correct format and fitting the terrain to each walk cycle. For this
you run the following:

python generate_database.py

This process can take some time - at least a couple of hours. It uses all the
data found in data/animations and once complete will output a database called
database.npz. If you want to change the parameterisation used by the network
this is probably the place to look - but note that the preprocessing for this
work is quite fiddily and complicated so you must be careful when you edit this
script not to introduce any bugs. You will also have to remember to update the
runtime to match.

Once you've generated database.npz you can begin training.

Thank you very much.
You said 'Various things including the skeleton structure are somewhat hard-coded', and I wonder what is 'skeleton structure'? Does it include the 3D locations of the joints? If I have a character which has the same skeleton basic structure (I mean the same joint index, the same father&son joints relationship) and the different joint locations, can I input the character to the trained model in this code without retraining?
