Hi,

When I import an iPi MB .bvh to Motion Builder 2011, save the file, and then reopen it, I get the following warning message:


I checked the documentation (no mention in 2011, but the 2010 Update doc mentions this issue) which instructs me to disable the 'Enable MB5.5 Limits' option under the Degrees of Freedom:Rotation property, but this option doesn't appear to be in 2011. Which, of course, is exactly what the message says, so I'm stumped. Is this anything I should be concerned about?

Now that I'm thinking about it, I'm not sure if this message started appearing only after I adjusted the rig's scale in bvhacker. I'll post again in a few minutes.

Edit 1: Okay, I'm back. The message DOES appear with the original iPi DMC exported Motion Builder .bvh file. I'll try characterizing the standard 'non-MB compliant' .bvh and see if it does the same thing.

Edit 2: Back again, and yes I get the same message even with the standard .bvh from iPi DMC. FWIW, everything appears to work fine but, as I stated in another post, I've only been learning MB for the past week so I'm not sure what the consequences may be for ignoring the warning.

Ah! All is good. I must have selected the wrong skeleton because now I see the option.

I'm wondering if there should be an option in iPi DMC's Motion Builder .bvh exporter to enable/disable MB5.5 Limits. It sounds like this feature is not typically used anymore and probably should be off by default.

Thanks for listening.

Edit: WHOOPS! There's actually a lot more involved to updating the iPi Motion Builder .bvh rig than just disabling this option. The complete process is a bit involved and beyond my current skill level.

I'm still not sure what compatibility problems may arise from ignoring the warning, so I thought I should mention it here for more expert users to consider.

After a little more testing, it seems like I get this error when importing any .bvh file, not just from iPi DMC. In other words, I no longer believe this is specifically an iPi DMC issue.

Does anybody know what this warning actually means and if there is anything I should do about it?

Okay, I see this warning message even after importing and saving the .bvh file that comes with MB 2011. I'm going to assume that this is a harmless, if annoying, bug in the program.

I've noticed the same thing, but it doesn't seem to affect exported bvh motion or fbx files when they are imported into other programs. I wouldn't worry about it.

Thanks for responding!

I searched everywhere for info about this alert message and couldn't find any mention of it except in the MB 2010 update .pdf, so until now I thought I was the only person seeing it and that I must be doing something wrong. Glad to hear the situation is common and nowhere near as critical as the message makes it sound.
