You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Make a character display for a cloth editor im working on
What is the issue? Surface Gui seems not showing (Rendering?) inside a Viewport Frame
What solutions have you tried so far? Well making the Surface Gui a Decal is a solution… BUT, im using a Sprite Sheet for the face meansss i need the ImageRectOffset for it, and neither decals or textures have it.
Heres a video of it
and the setup of viewport
Also im using the same Model as the Character’s Model so there’s no way that’s the issue.
And made sure the image is set up to front face of the mesh.
I have tried once to use SurfaceGui inside ViewportFrame, and It didn’t work. I wanted an image in the viewport so I ended up using Decal which worked fine. Perhaps you could try using Decal for the face inside the viewport?
