Problem with edged Normal Maps in Render

[AlexxCentral]

Hello,

a very basic problem:
I have a Lowpoly head and a highpoly. When I create with MultiMapExporter a NormalMap (tangent space, adaptive, from SD1, 4k size) and use it on my lowpoly basemesh in 3dsMax, then it never looks clean smooth. I can see all the edges.
I tried already different settings, how to set the normals of teh basemesh in 3dsMax between 0° and 45°. (And also it is of course linear (gamma 1.0) and used in VrayNormalMap node.)

Attached a Render screenshot with two different settings of normals, both do obviously not work.

I Imagine, that the lowest Subdivison level in zBrush should have more smoothed normals before creating this map.
Other applications can display a lowpoly very smooth and I image a normal map just to add details on top of that.

Attached at first a picture of my render in 3dsMax after applying that normal map.
And below a screenshot of the lowpoly in zBrush, which is in high Subdivison level (SD4) of course completely smooth!

• Furthermore I wonder, if I could export NormalMaps with 16bit?

Thanks

Hi there, you know i’ve experienced the same issue before trying render out normals from zbrush while using a mesh that was imported from another program. For some reason my uv edges were laid out correctly but every edge was cut (meaning every single polygon was a uv-shell for some reason) this replecates the grid-like issue you’ve posted. I think it may be useful to have a look at the uvs

Of course my knowledge of ZBrush is very limited so far I think you can work around this by using zbrush’s uv master orrr simply click on smooth normals in multi map exporter.

Sorry if that didn’t help!

Hi,
it is all done by UVmaster. And I have actually a lot experience in ZBrush export import.

Anyway I have no solution, I solve it now in other software like substance.
Which is sad…
There are quite often issues with displacement or normal map.

I guess I will have one day to try out marmoset toolbag, which seems to have the best and reliable baking tools with instant control.
