Pulling my hair out!

Cheathem

Heres the situation. I have a low poly poly inside of max, and i have a high poly model in max. I am trying to bake the details of the high poly to the low poly. Simple right? Of course not.

This is the result im getting:


See ho you can see the individual faces?
I dont know what that is!

Both models are shaded smooth.

The uv's are connected.

The faces are connected.

The normals have been checked.

I have tried baking inside of Xnormal.

I have tried baking in Z brush.

I have exported both models as obj with minimal export setting and re imported
them back into the scene and its the same thing.



I dont know what else to do!
Any help would be greatly appreciated!

Also, when i import the model into zbrush, it seperates the faces of the uvs into individual faces. Maybe that is a clue to whats happening.

Thanks in advance!

"Both models are shaded smooth."
By that do you mean smoothing groups?
If not, try that.
How does it look on your model?

Could you just upload the model as an .obj so me or someone else can take a look at it?

Fwap - Yeah smoothing groups. Just one shading group per model. Model looks smooth. Herw what it looks like in view port.



Rune - Sure! https://www.dropbox.com/s/qo4d8xl3o1hd66i/UndeadMinotaur_HighPoly_HeadExportTryingToFixShadingAndUvProblems.obj

SargentCrunch - Ill give that a try, thanks!

Cheathem

Didnt work Sargentcrunch ):

Rune - Sorry, that was the high poly(which you may also want).
Here is the low poly.https://www.dropbox.com/s/4di2gk4rq6ljd4o/UndeadMinotaur_HeadExportTryingToFixShadingAndUvProblems.obj

It has to be problem with exporting. The model you uploaded has hard edges. Try looking into export settings.

another quick shot, how does your model look with a checker applied?

Try applying a normal modifier, then another normal modifier (not sure which version of max you're using but in 2014 i have this fucked up issue where if i uncheck "flip normals" in the normal modifier, the modifier doesn't actually reset the normals, so i have to apply two modifiers so it flips the normals twice... it's bullshit but it works). Then an edit mesh modifier, then project, then bake.

[ame="http://www.youtube.com/watch?v=yeczjVAqznM"]Cage Creation - Baking 3dsmax and Xnormal - YouTube[/ame] tried this with your meshes with no solution, this is one weird thing.

FIXED. B

Re-do your UVW, it's a mess.


When i loaded up your UVW in Roadkill, i noticed that alot of edges where not connected creating the sahding issues.

I reset the entire uvw and redid it in Roadkill to see where that would get me.

I re-did it REALLLY FAST with RoadKill! litteraly took me 3 minutes. and this is how it turned out!

Now bare in mind i am no character artist and still a student at Games Academy in Berlin, so the uvw is shit, but you can do it better!

What do you see when you apply the normal map into the low poly? Can you see the facets or does it look smooth?

I theory this would be OK, if it shaded fine then who cares, right? There are several potential problems though... 1) if your target game engine doesn't use the exact same tangent basis as 3ds Max, then you're screwed. 2) texture compression will cause a ton more artifacts, with all these sharp-edged extreme gradients. 3) this normal map will cause a ton of LOD (level of detail) artifacts. 4) everyone who sees this in your portfolio will laugh.

Like wirrexx said, redo the UV's on the low poly.

Corrupt UV's can happen if you edit a model below the unwrap modifier. Sometimes the UV's will *look unaltered, but what happened internally is every UV Vertex was bumped over one number.

Same thing happens with the Skin Modifier.

You're 100% right I was just trying to get more info to figure out what was going on. I've tried over here and got the weird results, and while it looked smooth when applied to the low poly, you could see some artifacts on edges.

I've tried redoing the UVs and it seems to fix the problem though!

Cheathem

Wirrexx - Thanks for going through the trouble and finding a solution. I'll re unwrap and post an update here

Bruno - Yeah it looks faceted ):

Eric - Very true!

monster - Thats a very annoying issue, i guess i need to be more careful with my stack!

Thanks for the advice everyone!

Cheathem

Thanks for giving it a go Bruno!

Cheathem

Success!





Thanks everyone, I can finally move on now.
