About Mask while training and after that

Hi, I have some question about mask.
When we extract face we have landmark based masks (Components and Extended) and NN mask that we choose( e.g. Vgg-Clear and Vgg-Obstructed ). In Train setting (Train > Global > loss) there is a check box for choosing mask https://imgur.com/a/PcgU2g5. From my understanding the selected mask will focus masked face area while Training. Right ? And when we convert there are many mask that we can choose (mask that included in alignment).
Q: While training, Does it train with all mask(Selected) or it just indicator to show where is face area ?
Q: Does choosing convert mask different from training setting mask effect/impact the result ?
(From my view it just a mask we can choose any mask [train/convert] and use erosion to crop excess part. In training it ablout alignment, mask is used for tell area of face . Do I understand correct ? )

Yes, the mask you select in settings is the mask that will be used for training
Q: While training, Does it train with all mask(Selected) or it just indicator to show where is face area ?
The mask you selected in settings will be used for training. If the eye/mouth multipliers are set to a value above 1 then the components mask is also used (as it identifies the area of the face that the mouth and eyes are)
Q: Does choosing convert mask different from training setting mask effect/impact the result ?
You should use the same mask for conversion as you used for training, Results are likely to be sub-par choosing a different mask,
(From my view it just a mask we can choose any mask [train/convert] and use erosion to crop excess part. In training it ablout alignment, mask is used for tell area of face . Do I understand correct ? )
In training the masks is used for calculating the loss. It is basically used to say that areas outside of the mask (background etc.) is not important, and areas inside the mask are important.
