Smooth AND Hard edges inside one Mesh

Hello Everyone,

I'm still relatively new to development for 3D applications and an absolute greenhorn when it comes to the FBXSDK.

 

I have a question which I was not able to answer myself, I did some digging trough the docs and this forum but no luck for me.

 

Here it goes:
I have a mesh which contains numerous polygons. Some of the polygons require to be "smoothed together" so that they appear as a nice curved surface.

The other polygons need to remain sharp-edged.

 

 This Object is a good example for what I am trying to achieve:

cube_round_edge.png

The area enclosed in red contains a number of polygons which have smoothing applied to create a rounded surface - while the rest (green area as an example) remains with sharp edges. 

 

Unfortunately I was not able to do this yet. The only way I have come up with is to split the geometry into two meshes - The geometry which requires rounding and the geometry which should stay sharp-edged. I then generate Normals for the "rounding mesh" using the "byControlPoint" method and for the "sharp edge" with the "byPolyVertex" method.

But I feel like this cannot be the correct way to go about it - it seems very odd to have to separate my geometry up.

 

I tried playing around with "Edge Management" and "Crease Utility" functions - but I did not get anywhere with them.

The documentation does not even hint if "Edge Management" or "Creae Utility" has anything to do with what I am trying to achive.


Can anyone point me in the correct direction?

 

Thank you.

i think you looknig for this
for smooth part
first select edges / in modeling tab - under mesh display / select soften edge
this rule apply to hard edges but for that
you must select harden edges not soften
simply as that

 Hey javaad! Thanks for taking the time, but unfortunately I am not working with any user-interface software to construct the models. I'm working with the FBX SDK construction the Meshes from C++ source code.

Aint no modeling tabs in my world 😉

 

Cheers
