When you go into Manually Edit Resources you can use the assets already there as a guide to what goes where. And you'll see the messages at the bottom of things the generator is warning you about.

The easier setups will have a folder format like above where you can match up FG to the face folder etc.
Here I've dragged the SV files from the folder in Explorer up to the upper right area and need to change the layer in that drop down on the right. Notice the file names SV_Glasses_p06 is the Regular file and SV_Glasses_p06_c is the mask file - that "c" is how it knows the mask file so as long as the names match it does that automatically.

The icon file is found in the Variation folder if that exists but you can see that its name starts with Icon and you just drag it up into that little box for the Icon.
Once you get used to it you can actually just build the stuff from here by doing New like I did there. Big thing to remember is to select the proper Part from the dropdown on the left side near the Icon box BEFORE you start dragging the files up into the files window to make sure it knows what part. Also it greatly helps to have the Tags set properly so the part can be found when you're using the generator. Depending on what part you're dealing with you might need to select the Mask Color on the right to match up like selecting Skin Color for a face part etc...
In the Files section you can rearrange by using the arrows on the side of the box and that X at the bottom right of the Files box lets you remove a file you accidentally placed in there.
If you can't Apply and Close look in the bottom messages area for something in red as that's an item it can't save until you correct it.
I have a number of warnings in there right now because those items don't have mask files but they're not setup to be able to have the colors changed. I tinkered with making a mask file for one of them but changing the color didn't turn out so great anyhow
So experiment and have fun. Worst case you'll find a bug and have to let
Schlangan know.
I've broken things enough times now I'm getting pretty good at starting from scratch and totally rebuilding the database in there
