That is brilliant explanation and advice. Thank you.

Thats a comment lol. Thanks a lot

I am glad I was able to be helpful. Thank you for watching

+Brown Human this process is called baking. I will cover this in a new video soon. Its possible to do it entirely in ZBrush but there are many other ways.

Brown Human, you are very correct in pointing out EXACTLY what a thousand people see but are afraid to mention. You're right, subdividing a low poly mesh defeats the whole purpose. These KZfaq video tutorials are made by people with no connection to students so they "THINK" they are doing people a favor by posting these little "solve all" videos when the truth is more in depth and complex. The END GOAL is project high detail 3D surface info onto high detail 2D map (a NORMAL MAP) to then wrap around a low poly mesh. But to do this, you first need a low poly mesh with a UV map. Any way that you can get to that goal IS THE KEY. If you can then attach this low poly UV map to a hi poly mesh, you can then "bake" the high detail onto the UV map and transfer it back to the lo poly mesh.... ZBrush is not very good at this. It is AMAZING for modeling initial detail, but #1 it often screws up maps without telling you, it rotates them, flips them, places them in bad order, plus you have no editing control over the individual UV vertices and edges. That is why ZBrush's strength is in modeling, but for maps and texture maps, it is not considered a "real" 3D program like Maya for example. BTW, when people say there is no need to transfer from hi to low anymore, that has more to do with alternate methods which are more advanced than lo-to-hi poly workflow, even though they deny that it is advanced. It is advanced to people that are new to this stuff. Floating Geometry is one of those methods, in case you're curious.

@Cory Lee lol this became true suddenly, since UE5 announcement

But why are we projecting when we still need to retopo and bake eveyrthing? I don't get it!

I’m sorry I don’t know about 3D printing well

@@yaschan99 thank you the same, the only regret is that ignoring this information between the object backing and the 3D printer; also because I have a 3D printer connected on another pc that its cpu has difficulty knowing how to calculate the vertices; since she worked in 3D, I excluded and asked the question.

u cant Z remesher try to keep a general figure small spikes are probably going to get all deformed or short compared to ur original model. The work around u can try is not remeshing but decimating and projecting because triangles will follow the shape perfectly. Other optition u can try with Z remesher but i do not think is going to work activate paint brush and paint red where u want more geometry and before Z remehser activate (use polypaint) to tell z brush u want more geometry in the spikes.

+therond gabriel well retopology and baking was not the subject of the tutorial. Should I make a tutorial on that?

Yes it can be awesome!

If you work with Zbrush for several years this becomes a second nature. Anytime If we need to change topology of the mesh the subdivisions need to be deleted. Because ZBrush will consider that as a different model. To transfer high frequency polygon details to another mesh this is still the way to do it in 2022. To bake maps at the end is the final process. This is just a way to get there

Yes it does happen, happened just now for me too. need to tweak the projection settings

Thank you I guess

He used this technique to fix the weird polygon stretches and get a more uniform polygon distribution. This 2M polygon rock will be used as a normal/bump map for a lower polygon rock (1-2k poly maybe)
