Zbrush FBX Export Scale Issue

CJE

Hey everyone,

I'm having an issue with FBX exports from Zbrush (4R7 P3).

I'm trying to export my high poly FBX from Zbrush to bake in Substance.

The mesh was scaled to meters in Maya originally, and my low poly is scaled in meters. If I import my low poly into Zbrush, it fits perfectly and if I import the high poly fbx export into Maya, it scales fine.

However, when I import the high poly FBX into any other program, Substance Painter, Marmoset, etc, it's massive, so it doesn't line up for baking.

If I re-export the high poly from Maya, it works as well, but I can't do that since many of the subtools are far too heavy and crash/freeze Maya completely.

So something about the FBX/OBJ's that  Zbrush are scaling fine in Maya, but not anywhere else.

Any ideas?

Thanks.

Zbrush  uses a different unit system than most 3D programs (I think it has something to do with optimizing the program so it can handle millions of polygons). 

To get around this, you can use the scale master plugin (which I think should work in 4R7), or you can use the export slider to make sure your Zbrush units match the units you want to export to. (here's a video explaining: https://youtu.be/n2xPrwI9o1U)

Hope that helps!

Thanks, this is what I had to end up doing.
