hi,

blender 2.74 will be able to import and use the normals as
generated by the CAD soft.

i show you a test with a nigthy build

the outlined object use the new improvement => no bad artifacts

That's great news Lawrence, that will be a significant improvement for Blender for rendering CAD data!

That's great, thanks for letting us know.

Now we just need a tool in MoI to tell which way the surface normal is facing.

Only for FBX export from CAD ?

<<< Some tools, in particular CAD ones, tends to generate awful ugly geometries when tessellating their objects into meshes (very thin and long triangles, etc.). Auto-computed normals on such geometry often gives bad artifacts, so it is important to be able to import and use the normals as generated by the CAD tool itself.

There is now the needed helpers in Blender RNA, which allows import scripts to set custom normals from read data. Currently, only FBX importer uses it.

Bonjour French Pilou

ça fonctionne aussi avec l' OBJ importer, je l'ai testé.

it runs also with OBJ Importer
