For anyone wondering what the underlying issue here is, its because the UV Islands are not being separated properly via seams and are picking up adjacent pixels in the normal map for each sharp edge. In order to mitigate this all the sharp edges have to be made smooth. If you would like to have a sharp edge, each edge made sharp must also be a seam. If the issue occurs still, try turning up the padding for each UV island when baking. Hope this answers someone's question.
@@Rex-xj4dj helpfullinx is right to a degree, that can happen, but you can still have tight islands without this issue occurring. Try and get a visual of the normals on each vertex, see it with your eyes, which you can do in Max. They need to share the same normal value per adjoining vertex for each polygon. If they don’t, your seams look like this because it splits off each island but retains the different normals in the vertices and this is what you’re seeing. The best way to see and test this is reverse engineer using a cube or something and you’ll see. So when you add correct smoothing, the issue goes away.
First, big thank you to the video maker! Thank to ApPortion for Blender mentioning the Blender Weighted normal. It was a bit tricky, only worked after going into the data tab and then Normals->Auto smooth. The modifier seems to either be full on soft or off, i can't seem to make any changes fiddling with the parameters. Still, seems like a fix. Thanks a lot! Been wondering about this for years
Man, u my fucking hero. Thank you sooo much! Normals was my big-big problem, my ass starts firing everytime, that i need to do it. Problem on the problem every time. THANK YOU!!!
@@VoidloniXaarii There is an work around for using this modifier. I had created a Python script for that I was porting that to a full fledged blender addon such that it would do automatic smoothing for you based on Edges (How Maya does it) and then I lost all progress to a Windows update and lost my motivation. If I complete that addon someday. I'll share the link here.
Edit > Project Configuration > Select > Choose your newly exported meshes with unified normals (or modified UVs, updated geometry, etc) > Bake again. No need to start a whole new Substance scene because you made some modifications on a mesh or a scene. It's not called a "non destructive" workflow for no reason. Nice idea this normals unify modifier. Never seen that around before. Seems indeed to make a damn interesting difference. Thanks.
Hi Han, you're right. But at this stage, nothing has been done and the clicks to get to the same position is about the same. However being knee deep in a project and noticing the issue, then modifying the scene is beneficial. Thanks for pointing that out :)
@@KevsArtStuff I'm using blender and this issue is just solved by getting the mesh into smoth mode before exporting, nevertheless i still got some errors, in the UV seams, idk if there would be any way to solve them since in painter i used tridimensional projection for the most and yet the UVs leave the normals look very ugly... idk if you got any solution to the seams xdd
THANK YOU great video totally saved my day for those who work on maya i did it by going to mesh display normals then stg like normal set to face then soften
I had to put higher padding between those faces and I got it fixed. However, if you do that, then your textures will have noncontinuities obviously. However, you can mitigate this by using triplanar projection in substance if you want to maintain that continuity throughout the texture. Worked quite well for me.
This is exactly why i hate unwrap so much. It's not about laziness but the fact that it causes SO MANY GODDAMN ISSUES!!! One with baking and one with the seams. I seriously hope in the near feature they will bring out the PTEX version for gaming assets. I mean for god sake with this shit.
Thank you so much for this, fixed my bake immediately! *edit* It fixes the bake issues I had with rough edges, but when exporting all the faces looked rounded and wonky, even baked it into the normal map despite the model looking perfectly fine in substance. When I load the exported map into substance painter or elsewhere, it just looks really bad. Any help fixing this issue would be great, thanks in advance.
Would you recommend turning sharp edges off as well? I have some enabled for my model and I noticed that most of those same edges were visible after baking.
@@KevsArtStuff oh ok, idk I've never used this stuff, I only made high Poly's before because I was working for movie company so when I switched to game modeling its completely different and I don't understand much about it :D
@@KevsArtStuff I did the same, but it all appears to be simply about flipping normal direction, not the issue you described. But maybe my google-fu is just bad. :D Thanks for trying though.
If you press F3 in blender and type in 'Normals' with your mesh polygons selected, there should be an option called 'Recalculate normals'. I believe this will do the same as the 3DS Max 'Unify' function used in the video - will basically recalculate the normals of the object for you.
I'm having trouble with seams in my Normal map at the edges of UV seams. Is there any way to fix this? Unifying normals doesn't seem to help in this case. I'm using 3ds Max to model and Substance Painter to bake
Haha, i just literally did that in Blender a few minutes ago for my own project... how odd :) Select your model, go into edit mode, select your faces, drop down 'mesh', go to 'Normals' and select 'Select from faces'. Worked for me. Hope it helps :)
@@KevsArtStuff just out of curiosity. Is Blender as powerful for modelling as 3Ds Max? Cause I tried Maya and it was horrible for modelling but blender is so enjoy full. What is your professional opinion on this?
black mostly means highpoly and lowpoly are so badly missaligned that rays scatter away too much. two reasons for that: 1.your lowpoly and highpoly models differ in scale very much, or do not sit right onto each other. import both in 3ds max and check that they are roughly same in size and sit exactly on same coordinates. 2. even though you already pointed highpoly mesh file in substance painter, it goes nuts when you resave the high poly file and needs to be reselected (inside bake menu)
Now the only thing left is to find a free version of 3d Max, cause all Autodesk production is absurdly expensive for someone who absolutely has no money
@@KevsArtStuff I imported my low poly model from zbrush to max, then i first added some smoothing groups and after that i did just like you in video. After 'collapse all' polygon count increased like 3 or 4 times

Can you please help me. I go to mesh display then what do I select?
Mesh display> Set to face and then Mesh display> Soften edge if I understand correctly! At least it worked for me!

Omg thank you so much!!!
Combined with specifics from the comments below, I fixed my Blender export issue and got a clean bake. Thank you so much!
Awesome thank you! this helped me get rid of a burden. "Unify" in max is similar to "Avarage" in maya incase anybody here wonders.

What is that addon that shows the shape on the top left, really digging it
That's not an add on, it's part of ZBrush. It was added in recent years (not sure exactly when), but it's always there now.

Without seeing it, it's difficult to see what the problem is.
Omg very good, but I have not idea how to do the same in Cinema4D.. any suggestion? Thanks
No, sorry
Simply use align normals, sadly this did not work for me but it might work for you. Just make sure your normals are yellow.
I didn't even know this was an error I thought it was normal for this to happen
I did this and it didn't work. Do you have any alternative solutions?
HI, can you make a tutorial about fix seems in painter ?
Thanks for reading and good job with the tutorials
have a nice day !
Hey, clone stamping is the way to fix the seems, and other than that, triplanar projections is the primary way to remove seems procedurally
This video is helpful to me
for maya what to do?
So if I understand right you do it on the low poly? Doesn't it break the UV's?
