I freaking love you! I have tried to make a simple head bandana for my first male look, but failed. The youtube tutorial on importing clothing from blender to DAZ had different buttons in their blender and my keyboard shortcuts didn't do the same as his, so I never finished it. This will hopfully get the job done! "Teach a man to fish"? You have just given us the whole bait & tackle shop! Thank you so much!
With heels you have 3 options: first one is to import everything like in the guide above, then you need to morph the characters feet into the heels shape because they don't have collision, the second option is to only import the shoe as a clothing item and use only the heels of the high heels that come along with virtamate by default which is kind of a special cua-clothing item-mix + morph that the developers coded into the game which you can't do yourself just like the other "special" clothing items like pants with different stages or glasses. But the in game heels are not very high so the use case of these are limited. The third version is to only import the shoes as a clothing item and attach the heels separately as a cua, this way you would have collision to the heels but you will most likely also have to add a custom heel morph to the model so the benefit is questionable. Maybe I will also do video guides on more complex imports in the future
