I've been resetting normals with TurnToPoly for years. In maya select the shape node and scroll down to "mesh component display" and select 'display normal' then set the dropdown underneath that to 'vertex' and increase the normal size value. The vertex normals in Blender are correct. In Maya, normals are used to determine the orientation of a polygon face (face normals), or how the edges of faces will visually appear in relation to each other when shaded (vertex normals). Conforming, on the other hand, can resolve issues when the normals or the winding order of individual polygons are incorrect, while the majority of polygons are rendered correctly. For example, you can make sharp edges appear smoother or adjust the lighting on a polygonal object by modifying the direction of the vertex normal. I have tired every import and export setting related to normals in Maya and Unreal, with no effect. Mar 24, 2018 · Adjust the normals via Maxscript. This isn't a bug. So this is very important to be able to control if we want to recompute or not the normals. . To make this work you would need to compute just single normal per face and add the weighted normal and weight to each per vertex normal structure just like in the duplicate link. Normals are imaginary lines perpendicular to each point on a curve surface. Adjustments. While we are all used to using the scale tool to modify shapes, sometimes it’s not always the best thing to do. It just resets the normals while respecting smoothing groups, and whatever other options you pick. The model has 100's of parts that are parented and mirrored using the duplicate/flip -1  method causing issues with normals when I import into Blender/Houdini. Mar 28, 2023 · Hi all, A client has sent me a model that needs to be taken from Maya to Blender/Houdini. Normals are a mathematical side-effect of NURBS. The normals need to be locked because there is a hard geometry edge there in the example (tho once the normal map is applied it will be appear as a smooth edge). if I remember well, this way normals will be correct both in max and maya with obj format. What are you trying to do? If two normals of exactly opposite direction are averaged, the result will be a zero-length normal.

I have been using the FBX format which works when the normals arnt locked just fine from Maya to Max. Thus, Maya will return the inverted normals. If I just import the FBX, in Blender, the vertex normals are correct. All 3D software compute vertex normals in their own way (Max/Blender averages last I checked, Maya has face weighting on by default) and you can further edit these vertex normals. ABxAC will give you the normal of the triangle. Please be sure to read our Privacy Policy. They can go on forever: moving faces, vertices, sliding edges, and tweaking form. Replace zero normals by. so my workmate usually make normals "Set to face" in maya and then make them soften edge(if needed). its actually pretty handy to have on because it actually tells you if your normals are flipped or not.
