In this model, https://poly.google.com/view/dXYoN00Ng8j), the eyes are not defined as separate geometries but rather drawn in the texture.

Since the texture has UV mappings, is there a way to write a script to automate the creation of geometries that match UV mappings?

1) In other words, could a script create geometries from the texture UV mappings of this elephant and create the eyes?

In short yes, but It could take forever to do so too. It could be much faster and easier to remove mesh faces at the eyes in the model and attach a modified sphere with UV Map/s (Duplicated) to display your details but ultimately depends on what your desired results are to be in the area.

  • $\begingroup$ Thanks for the answer, Dave. The goal is to write a script and repeat the process for other models as well. How long do you think it would take to write a script like this? $\endgroup$

  • $\begingroup$ Hard to say exactly for me as I don't know that it has or hasn't been done before and far from a master programmer. With some knowledge, research and lots of attempts a willing body could be testing in a month or 2, or more depending on time available/applied. Could be much longer too even for the experienced depending on testing, compatibility, glitches etc. etc. $\endgroup$
