Closing the Back of a 3D to Low Relief Sculpt

[system]

Hi,

This is my first question on the forum.

I’ve done this sculpt in 3D.

I then rotated the model and scaled it in Z to compress it into a relief. At this point it is a flattened version - but still not like a relief.

I then removed the polygons which are facing the back side. This of course leaves open edges.

Now I want to close this off and place it on a flat surface. Essentially I’d like to select the open edges, extrude them straight back, then merge this with a thin box. It’s the “extrude the open edges” part I don’t know how to do.

Any thoughts? This is my first attempt at this and if you can point me to information or resources I’d appreciate it!

Thanks,
Mark

you could have just flattened the back instead of deleting it i think.
you could also just place it inside the thin box and dynamesh, what is your intended output?
extruding the edges would be easier if you had the back geometry but you can close holes, select the back polygroup, move and then extrude, then delete that polygroup if you want it open.

I think I would have just trimmed the back off instead of deleting polys.

Yeah I was thinking that reliefs had to remain essentially convex. That the silhouette as viewed from the front needed to go straight back. In looking at some traditional medium relief sculpture images I see there were often undercuts and features “on the back side” but still above the background. I guess only for those carved directly (as opposed to cast).

So here are two images using the above suggestions. I’ll have to get used to the idea of the ear behind being visible

I think I need to print one and see how it feels to look at the real thing. Thanks for the suggestions.

There are some tips and tricks in this thread - have a look:

Thanks very much for pointing that out to me, Thor.
