Question is a bit unclear to me. Can you rephrase it, perhaps? Seems like you are asking the same thing twice. Project in zbrush is not the same thing as bake in substance painter. If you tried to Project high poly detail onto a low poly model, you wont actually get that detail because there is no geometry to support it.…
Projection tries to match the position of vertices from one mesh to another. So a mesh is just a ton of vertices and each vertex is a point in 3d space. For example, 0,0,0 is the origin. 100,0,0 is 100 units in positive X direction. So if you have MeshA and you project it's details to MeshB here: you'd get: If MeshB didn't…
You can of course just not bake things and just work with the polygon count you have. For a game character it depends on the perspective and the game. This can be from 500 to 10000k and more polygons. At higher polygon counts or depending on your artstyle you might not need any bake at all, but generally it is still…
Yes, a reprojection is done for when you want to keep using this highpoly mesh for something directly, like animation. You basically fix the topology of your highpoly mesh to be better. This is surely mostly used for non game things. In some cases you can also reproject to keep working easier, like if you want to have a…
@goddessjuno There are many reasons why you would want to retop and project, but there are fundamentally two different cases you should be aware of. Each has a unique purpose and goal. Generally, you will be dealing with both. And a mesh that is optimal for one is not necessarily optimal for the other. Case 1: Sculpting…
@Alex_J I sorry for the confusion, I've been self teaching myself 3D art (I'm focusing more on character creation) and they're some parts of the workflow that are still confusing to me. I've seen people use zbrush or blender for projection (sculpt high poly, retopo, then project high poly onto the low poly model), then…
@Shrike That makes more sense, so reprojection is just to make a high poly mesh workable again (i hope that's proper english), or essnitally just giving it better topology. High poly to low poly bake, is to make the model look like it's high poly, using textures. You added that projection isn't used for games. Does this…
