You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Placing a flat/static image on a Dynamic Head while passing verification check.
What is the issue? Traditionally, you could place a decal on a Classic Head for the face, which is valid for classic but not Dynamic Heads.
What solutions have you tried so far? Placing decals on head, placing texture on head, looking on DevForum for those with similar problems but nothing.
For some reason reference roblox head lost it’s UV Map when imported into blender so it exported without one. I created one for the front of the face/head and now the face appears! :]
Like Hazel said, you have to apply your own UV map since it doesn’t import from Roblox’s head obj file. There’s many tutorials online. Remember to only unwrap the front face and not the sides and back or top/bottom of the cylinder so you only need to use a face decal rather than a full map.
As for cage, I used the SemiRealisticMale template from Roblox’s post. I don’t know if I can post links on here so I recommend googling it.
