Max precision in OBJ export?

system · July 3, 2019, 8:49am

Hello,

I’m trying to figure out how to tell ZBrush to export a tool with max floating point precision.

Usually it is rounded floating point up to 6 number, but I work on high-scale and sometimes +/- 1 can be noticable at the output rendering. So if I can force fixed width 6 numbers or even double - that will be of great help.

Thanks!

As far as I know, ZBrush will only export as floats. You may see slightly better results if you export as FBX but you’ll still get rounding.

Duh! Not good news, but I guess I expected it. Is there some option with script or so? The OBJ format is simple for my case…

No, scripting can’t affect export in that way. As I said, try FBX.

I have workarounded through using FBX as you suggested then using assimp to export as OBJ, luckily the tool export with high precision coordinates. It is kind of slow operation, but at least a solution. :rolleyes:
