He's using TrimCurve brush with auto-polygroup on (ctrl+right click with this brush on your model and enable the polygroup from curve/clip or whatever it says). It basically creates a new polygroup on each cut you make with a clip/curve brush. He starts on "solo" so only that subtool is visible, cuts a whole bunch of small polygroups, then uses Split/Delete some groups, ZRemesher, and then "Append" polygrouped pieces to the main helmet mesh. Then in EdgeLoops he adjusts some settings like thickness and bevel, creates several series of PanelLoops on that piece, createing support loops to make cleaner better shaped beveled edges with more polys on those edge areas. I'm really not too used to doing the edgeloops and stuff in Zbrush. I do that stuff usually in my main modeling program, and use Zbrush for the organic sculpting but I need to get better with Zmodeler and similar tool operations to fully open up my workflow better. The newest quick and easy way to get totally clean flat edges when you trim/cut the mesh (without all the jagged edges) and retopo automatically is this (SUPER CHEAP PLUGIN): www.artstation.com/marketplace/p/2kAb/eazyremesh-tool-a-retopology-plugin-for-zbrush

@@cc0cg ah wow thank you for sharing!! I'll check it out!!

It's Zbrush.

Yup. 3dsmax for polymodeling. Sculpting in Zbrush. Render in Keyshot and post in PS.

@@andrzejmarszalek103 thank you

nah, human sculpts, military vehicles, guns - whatever you can imagine, I've seen tones of different sculpts and it's fascinating! :3

@@albertpxl vehicles?

@@higorss yes i've seen people doing vehicles only with zbrush

@@paulatreides6711 sculpting?

Yes

I've designed this in fly, without concept....or even idea at beggining :D

You know, alot of crying. Since he didnt do it for a game im sure he cheated quite abit in that area. I know I would :P

Bit by bit over many days I think. I can't imagine how to nicely bake normal maps for a low poly version of this! So much detail!

i think he don"t retopo , import file in Keysot and render

@@neoqueto yeah baking tricky and intricate shapes is what took me the longest to learn in 3D because there isn't much resources out there on the subject. I currently use blender with cages for it. I separate the parts of the hi-res by known increments so i can easily put it together later, create cages for each part, bake, then put together the low res. it works with the most complicated models

@@neatpolygons8500 sounds like a good workflow, thankfully I don't do game models. And by separating the parts do you mean splitting a single mesh into multiple meshes or if a model consists of multiple meshes you just bake each piece?

Every time I see this technique I'm curious about how they solved this exact part. There's always a question in the comments, never an answer :( I honestly have no idea for a solution. I'd wager you simply don't. None of the videos using this technique I've ever seen are pixel clear. I'm guessing the compression and/or upscaling of the videos hide the fact that there's probably a bunch of jaggies everywhere.
