    Seems like your post is lost. Yes it’s almost the same, I prefer my because I can keep 4 side poligons as much as possible for better shading.

    I prefer my because I can keep 4 side poligons as much as possible for better shading.

    Using the Triangulate modifier by just adding it preserves the entire model, it keeps every 4 sided polygon in the viewport and in edit mode so hard surface modelling can continue, it also preserves normals whereas Triangulating in edit mode that you suggest actually triangulates the mesh there and then and destroys custom normals.
    This modifier automatically gets “applied” when you export so there is no need to apply it yourself. The additional bonus is that by just having it on a mesh shows you what the model would look like (without applying it) in verge.

    The rule here is never apply it as that WILL screw up the mesh. Because the Verge3D exporter sees the mesh as triangulated (because it applies modifiers on export) it must skip that process. The Blender triangulation modifier does a better job as it preserves the normals whereas the Verge3D exporter does not.

    Hard to explain? sorry.

    Please try it to see what I mean.

    I made a video showing the entire workflow and how to preserve normals without triangulating the mesh in edit mode.

    Hah, seems that they improve triangulate modifyer since last time I used it. :good: Usualy it broke normals and triangulate all mesh.

    Yeah, I noticed you can still see the triangulation if you switch to wireframe mode but it does not create actual edges like edit-mode does making it very useful.

    Hi d3pixel, we fixed this issue, now the exporter should preserve custom normals. This fix will be available in the upcoming verge3d release.
