Low Poly Display

Anonymous — Fri, 09 Mar 2018 10:02:49 GMT

Hi,

already searched help and forum for this issue. I have a low poly model as fbx and obj. When imported into alias and diag shading they appear very different - obj is smoothened along edges whereas fbx model has sharp edges like desired. Is there a way to control this apperance in alias hardware shading and rendering.

Thanks for replying.

Best,

Andreas

Have you tried turning off the "Keep Normals" and "Merge Vertices" options in the OBJ import options? I think that should fix your issue (unless the OBJ file itself has already merged the vertices)?

The reason the OBJ image does not have the "faceted" look that the FBX image does is because the vertices have been merged (either on export or import) and the face normals have been averaged (resulting in a smooth look).

Hi Wayne Olive, thanks for replying.

I think it has to do with exactly what you are describing. If I take the imported obj and subset each vertices I get the look I want.

The thing is even with the unwelded FBX file, exporting from alias as obj and reimporting in alias again with "merge vertices" and "keep normals" options off - the imported OBJ is always welded. So far I did not succeed to import any obj file where these options function properly. The imported obj is always welded/merged.

Can you check this and is this perhaps a bug?

best,

Andreas

Hi Andreas,

I was able to achieve the desired display on an OBJ, it was independent from import/export options. See attached image:

I selected the OBJ, chose "Flat Shade Meshes" in the control panel on the right, and used "mulcol" as Diagnostic Shade mode. Does this help?

Cheers,
