How can I make a helmet

So I am making a helmet for my showcase and I’ve never really made them, I can make a helmet type shape but I always get stuck on making the sides for it which will make it look more unique than a bland helmet but any time I try to it’s either stretching out too long or is just too small for me.

You should use blender to do this. You modle it in blender then export it into Roblox. There are lots of videos of youtube showing how to use blender and how to upload things to Roblox from blender.

I do use blender but as said, the part always looks disformed

Easily make it by using blender. Which is what I use.
