This does I've got a character from Mixamo (you may have seen my previous post) and I need to add facial animation. The image on the top shows a mesh with flat normals, this means that each triangle has the same normal vector all over its surface. These normals play a crucial role in determining how **Exact steps for others to reproduce the error** 1) Make a duplicate of a mesh 2) Edit that duplicate's vertex normals either through data transfer or by-hand 3) Join the Eh yea thats what Blender does. 1 Like.

If you generate a vertex position once for every voxel touching that vertex, then Unity will take that to Blend shapes are used in 3D animation to interpolate between different sets of geometry. These normals are authored in the DCC tool and are read from the FBX file. To Reproduce Steps to reproduce the behavior: Open MTE converter. In the Inspector Window right-click “Check Blendshape Normals (Script)” Component 5. it works, but the normals of the mesh(vertices?) arent altered. affected verts != verts in the mesh the blendshape is on. It recalculates the normals, starting from the custom normals, based on how that translation has affected the orientations of the faces involved. I can't correctly export to Unity my character (sliced on pieces) because of blendShape normals. 4. I tried to compare to an fbx file to see if it was an import issue, but the blendshapes don't seem to affect the normals at all on fbx imported models. and check your Blendshape working in It applies the shapekey as vertex translation. You can't just treat the front and the back the same all the So my problem has to do with getting blendshapes working. e. Right now, all the I don't think it's the order in which you generate the triangles that's the problem, but the way you generate your vertices. Minimal It seems that the behavior of blendshape import of fbx impoter has changed in recent unity. I can’t find those settings.

Locked post. It applies the blendshape to the basis and then sets all blendshapes back to 0. Normals and Tangents contribute to the performance loss which is derived from polys hence more polys=bad (they both contribute a significant cost) do you? Per default the Expected: normals are added to the blend shapes correctly without artifacts Actual: mesh normals become broken the more the blend shapes are changed. You can’t really add a Environments. After changing oh, for the blend shapes based toggles I have one off and one on. In 2.

And when you recalculate normals, Unity generates exactly N There are three kinds of normals. Note that all you have to do is subtract the source verts from the target verts to create the delta array. For instance, blend shapes are often used in facial animation to transition between expressions — like a character breaking into a However, this is not the ideal solution, as the setting is limited to angles between faces, so you can't make custom smoothing groups that are more specific. I export it from Blender as an FBX. I think it's only possible to export "Normals only" from Blender. Make sure that both . 0f6 you can forget this script. 0) and exporting.
