Proxies are rotating randomly when I export to MXS

Proxies are rotating randomly when I export to MXS#340983

I've got a file where I scattered a bunch of grass proxies via 2011's object paint. If I render straight from 3ds Max it works fine. But if I export to MXS the grass proxies are rotating about their axis seemingly at random. Has anyone run into this before? Any ideas on a fix?

Alternatively, is there a script where I could replace all of the proxies with instances?

One thing I know is that it's not the same to hit render in 3dsmax than to export to mxs. The latter does not exchange xref objects' proxys for their hipoly version too.

Where are you seeing that rotation? Did you render the MXS directly in Maxwell after you exported it, or did you go through Studio?

I'm seeing this in studio. I'm trying to combine an MXS from 3ds Max with an MXS from SketchUp so I need everything to look kosher in Studio.

Under some circumstances, Studio has trouble reading object orientations from MXS files, because the way they are stored is ambiguous. I'm afraid there's not much you can do in this case.

It's true that sometimes exporting from the file menu produces different results compared to rendering because of some limitations in Max. To make sure this isn't the problem here, try enabling MXS export in the render options in Max and hitting render. Open the resulting MXS in Studio and if the orientations are still messed up, it's the problem mentioned in the first paragraph.

So there's no fix. Then I need a workaround. Any ideas there? If I find a script that replaces proxies with instances could that solve the issue or should I try something else?

I found a solution. You were right in that the scaling and stuff was pretty weird in the 3ds max file. Lots of the scales were negative numbers and such. This must have been from a mishap when I ran a script to randomize scale and rotation.

The solution was to use a script to replace all the proxies with instances and then reset the Xform. Now it's working properly.
