Model generates cutoff heads all the time #168

Trying to figure out if this is a problem with my training data or maybe the way FluxGym is setup. One of the models I trained is constantly producing images with the subject's head cut off. Most of the time at the forehead and frequently right at the eyes. No amount of prompting seems to prevent it from doing this in more than half the generated images.

I'm wondering if this is an issue with my training data. In the data the subject's head is never cut off and has a fair amount of room above it in all the photos. I have the "resize dataset images" set to 1024. I'm wondering if this might be the problem as many of the images in the training set are 2669x3999 Also a lot of the images are full length (head to toe)

I'm wondering if the "resize" setting should be different or if some of the more advanced options need to be changed. It is acting as if a lot of the training images might have been cropped or something.

I have the same Problem. resize ist set to 512 and the images in the Training set are about 960x1680. Everything else is at default settings.
