Yeah, there are more than 1100 weights being trained in the network each taking ~5 iterations on average (aka. physics updates). What's limiting the training speed ultimately is that the loss function needs to wait for the physics update.
If you need to convert a lot of models to the same "source" it might be quicker overall if you properly train a fresh network. After that just hitting apply should be enough to match.
At the first step of training, what it then does is look at the source you just loaded in and it compares this to the "saved" training data it has on hand?
Currently I'm still a bit confused about the training process, since it refers to multiple things at the same time it seems.
The training data by default is a "morph training" that you have included?
But when I click the train button, it also retrains it's existing default profile, by looking at the new source material and then, apply this "new training data" onto the target?
Or is what you are saying that I should in this case;
Press the button "start from scratch"
Load my source model
Load my target model
Press train
Now it will create a "new training" data based on the source model?
Where as before, if I did NOT click the "start from scratch" button the only training that would happen on the target, was based on the original training data that you had provided? Or does it still look at the source model I just loaded in?
I'm confused by the difference between the two, why would starting from scratch be better then using the pre existing training file?
Because the newly created "start from scratch" training file will be solely foccused on the custom source models morphs which should give better end results?
Or faster?
EDIT*
^ I think I answered my own question heh.
"start from scratch" Will make it so that the training will solely focus on the source you provided, granted you train the data a bunch of times which makes it so that you can just press "apply" with reliable results to your target
Where as if you did NOT start from scratch, it will look at ALLOT more data, redundant data, combined with the source appearance you put in, which results in less accurate targets if you were to press "apply".
HOWEVER, pressing "training" while you have the default training data loaded in, will "retrain" the default training data?
Correct?
