most annoying Maya to SP problem i ever had

dimdim · May 2019

hello everyone!

i have a problem with my mesh when i was trying to export my mesh from maya (lowpoly) the normals in maya are normal but for some reason in SP 2019 dont seem to work fine
i tried everything
-Unlocking normals
-Turning on Smoothing groups when trying to export and OFF as well
whatever i do i still get that issue

The answer is in here:

It's real simple fix. Just got to know which program uses which tangent space. Then you just tick a checkbox.

Triangulate your mesh before exporting.

Hi! Did you solve your problem with shading in SP?

If not, make sure that you perform maya "cleanup" check before export. In 90% cases with that kind of issue topology has nonmanifold geometry or UVs has places with one vertex connection.

I get this issue occasionally. Sometimes all the vertices are not welded in Maya. After I do a vertices weld and export, the problem is solved.
