Baked sculpt object meshlines showing

I have a brain I just sculpted, and have been trying to get a good baked object from it. I've tried multiple resolutions and settings (different types of normal maps and displacement maps) and they all end up with strange phong shading where the edges of the new polygons are.

I've tried changing the phong tag settings, but to no success.

Anyone else running up against this issue? Or is my real brain just baked? (hahaha)

Well after two days of experimenting and fiddling with this thing, I'm seeing that the maps that are being baked out by Cinema are not of the quality of those that come out of Zbrush.

Our solution, in this case, was to export the level 0 mesh and level 6 mesh from the sculpt in Cinema to .obj files, pull those into Zbrush and re-output normal and displacement from there.

viola! It works perfectly.

What the heck???

Why sculpt in Cinema if you have to take it elsewhere for a decent baked output anyway?

This is my first sculpt and first attempt to bake it within Cinema. I'm sure I'll find the issue in my workflow, but the fact that it worked flawlessly from Zbrush on the first try says a lot.

That helps smooth it a bit, but is still not correct.

Zbrush to the rescue.

I had this issue with an intensity displacement map, it was not very strong, so I used a filter in Photoshop, I am not completely sure about the English name, called Gauss diffuser scrim.

When I had the same problems with normal maps, I just put my object into a HyperNurb on subdivision 1 and that helped a lot.

I am kind of getting the feeling, that it always depends on the scuplted object, as sometimes it is working and sometimes, if the objects are complicated it messes up.

Yeah, I'm sure I'll figure out what the issue is at some point and learn to work around it.

It's just very frustrating.

We did nothing special, and just took the two exports (level 0 and level 6) into zbrush and were able to export PERFECT maps.

So there's something wrong with the way it's working in Cinema, or the way I'm doing it in Cinema. In either case, I can't seem to find where the problem is. I'm sure as I get more experience with the sculpting tools and bake things down more often, I'll see where my error lies, or where the "issue" is in Cinema and find a work around.

It's just a matter of time and experience at this point.
