How to Import smooth version of Low poly mesh from Maya in Marmoset toolbag 3, since marmoset doesnt have Catmul-Clark

[creativebug72]

Hi guys so I am having difficulties with my mesh export, When we press 3 key in maya to smooth our model. I need that smooth version of low poly in marmoset to apply my textures correctly. But I am only getting the hard edges version and normal maps are only working for texture but it does not smooth the overall object like it does in Maya. I hope I was able to express it correctly. Please help

If you really need the smooth version, you must subdivide your mesh in Maya and export it after that. In this case, the menu operation is called Mesh -> Smooth in Maya.

But will definitely be a heavier mesh...
