In IronCAD, I created several parts with different color and then export it to obj and step(203 and 214).
And then import that obj file, but all the parts are combined into one object in KeyShot.
And when import step file, there is nothing imported in KeyShot.

I just found why I could not get any data when import step file created in IronCAD.
If any Korean character is in the Path to the step file, then nothing is imported into KeyShot.
So I moved the step file to root of D:\ drive, then it works fine as a separate object.
