ZBrush decimation artifacts (also, hi-to-low workflow w/o normal map?)
polycounter lvl 4
Hi newbie here. First time trying to get Zbrush to low poly for game (WITHOUT baking normal i.e. for a mobile game).
I keep getting hole artifacts though if I get the poly count to a viable number (My topology seems fine beforehand):
I think it might be my overall workflow (varying densities in mesh). I've tried using projection but it creates an awful cage mesh.
All the tutorials never had this issue. If someone could help a newbie out, I'd greatly appreciate it. Thanks!

To be honest this is not a good way to get a low poly mesh for a game. Z-remesher can work, but you still need to clean it up and make sure you have your UVs set up correctly with hard and soft edges where they're needed.
Parts of your mesh look like they're already low enough, are the higher density ones different subtools? I'd split them off, duplicated, and z-remesh. Then project and see if you can use lvl 0 as a starting point.
use zremesher, turn off adapt
you want to combine elemets in zbrush , try merge all subtool, and turn that into dynamesh, the mesh should be combined no hole for good, then you can start z-remesher from that.
OR even better, since you mention for mobile,
try to do it manually. you can remove unnecessary geometry elements.
why not baking normal? it will help your texturing.
