forehead wrinkles

Postby Joshea » Thu May 02, 2019 2:15 am

Hi,
I'm looking for a forehead wrinkles target asset for the attached character. He's suppose to be around 70. I'll try and make one, if nothing is out there, over the next couple of days. :D

I'm not necessarily saying that this is how it should be done, but an alternative approach would be using a normal map. The mesh density in the forehead might not be enough for believable wrinkles.

I tried sculpting in the forehead wrinkles, however, rendering became a major problem. The modifier, multires, creates too many vertices. Slows down my mac mini way too much.

The answer to this point, put a hat on the character that covers the forehead. Thanks all anyway.

Normally, you'd only keep the multires until you've baked the normal map. Then it can be removed. See for example https://www.katsbits.com/tutorials/blen ... l-maps.php

Theoretically, you should be able to mask away all vertices except the relevant ones during this procedure.

(This said without knowing if the mac mini would be capable of this either)

Here is another workflow: if you are already in Blender, also need the geometry for wrinkles and do not want a normalmap you can do the following:

just select the faces of the forehead in edit-mode, then select "mesh" "edges/subdivide" with e.g. a factor of 2. Then only the forehead is subdivided. The skin texture will not be destroyed, weights and groups will be copied so it should work while posing.
... now do your weight painting ... I did a quick test on one of my characters ... not very natural, I know. But it show that it works.

Btw.: This should also work on a Mac Mini. For posing etc. switch subdivision surface off in edit mode, if you use that. The first 34 pages of the "gallery/the daily life of models" were rendered on a small quad-core MAC Mini.
