Thanks for the reply...
I've made a simple steps with this scene:
1. I've created this object in Sketchup
2. I've exported the object to 3ds file for MAX
3. I've imported the scene to the MAX
4. I've made an export to Octane from MAX and from Sketchup using Octane plug-ins.
I haven't changed anything in Sketchup before an export (axes and other settings) I've just created a simple cube, that's all..
This problem disappears when I manually re-import created OBJ file to the new Octane project.
Is it normal, that texture scale after export from SU to Octane doesn't the same as in Sketchup?
This is a floor texture mapping in Sketchup:
This is texture mapping in Octane:
