Hi!

I am facing some issues trying to bake in Substance.

I attached to files That I created to test Substance.

Here you can see what happens. A very bad edges. I am using here 2048 in resolution that need to be enough for a so simple geometry.

What I am losing here?

 

thank you

Hi @a.bisewski,

 

Thanks for the question and for the meshes, this greatly helps troubleshooting.

 

This is not really a deal of resolution in your case, but more about Normals and baking preparation.

 

First of all, hard edges can be a pain to deal with. Usually, we advise to add a simple bevel on crucial parts, in order to avoid artifacts. Also, cylinders will always have wavy artifacts, due to differences in topology between the high and low.

 

 

With that being said, in your specific case, I would remove the sharp edges on the low poly (which prevents to fully smoth the edges), and make sure its surface is "inside" the high poly.

 

 

In most situations, this wouldn't be important, but with hard edges, it should help to reduce the artifcats.

 

 

 

Let me know if this helps.

    Hi Cyril. Thank you so much for your attention.

    Your answer really help me a lot.

     

    But I am also facing another problem. While my object is a single part but very complex, my uvs mappig is too small.

     

    When I isolate one region of this model and rescale the uvs map all the edges is baking perfectly.

     

    Why? My object is a mechanical part and have external and internal areas and like a said, is a unique body.

     

    To use this model in Unity3D I can´t use huge sizer like 8k

    I tried to remove the interior area and create another object with this. So I had one body for interne area and one for extern. So I could to resize a little the uvs and ok, improve, not really perfectly but better. But now as we have this seams opened in the body, Substance have  difficult to work or create rounded edges there , like I read in doc, theses edges cant be the rounded because the vectors...
