Projection Issue

good evening,

I have built a high poly model for a games model to then project onto a low poly that i made with quad draw based off a decimated version of the High poly. Although, now that i got to the projection step of my workflow Im having a issue with projecting my high poly onto my low poly. A lot of the information is getting lost and often times the information from sub tools behind other sub tools (i.e. a shirt underneath the armor) is getting captured rather than the opposite like intended.

This is the lowPoly
High Poly
Projection after first divide, can see all ready lost info in forearms area
Projection after 2nd divide, further loss in arms and now chest gear and waist sash

I’ve looked up guides already on Projections and as far as i can tell i have been doing it correct, but if there is and any recommendations of a more definitive guide or better advice in general it would be greatly appreciated . thank you

The new mesh will need more geometry in order to capture the detail. So you’ll have to project, subdivide, project again, subdivide, etc.

Overlapping subtools can be a problem, as you’ve discovered. It can help to either separate both models into several subtools each so that you can project each individual part manually. For example: have a highpoly and lowpoly skirt so that you can isolate them and project without having to worry about the different parts. Alternatively you could try dynameshing the high resolution sculpt in a way that it becomes a single surface where nothing overlaps.

And last but not least, it might be worth asking why you are even projecting the model at this stage if you already have a highpoly and lowpoly model. If your goal is to bake maps for a video game, then you’re much better off using a dedicated baking program such as xnormal rather than zbrush.
