How Model Viewer can change physics parametres?

I’m porting some stuff from Alpha Protocol and i’ve got problem with physics of model. Knees are bent in the opposite direction etc. I heard that it’s fixing in Model Viewer but i don’t understand how. There are “min” and “max” values and they influence on bones, right? But how can i apply those values on model? When I push “Generate QC” nothing happens. Is there some kind of tutorial for this?

If you press Generate QC the QC is in your clipboard. Just paste it in your qc.

You basically make the bend limits in the model viewer and then click generate QC. This will save the limits in platext form into your memory from where youcan the copy paste them into a QC file from which you can then generate the thing.

Thanks.
