When burning out, wheels turn backwards

Didn't notice this until i changed frame rate to 240 from 24 so that i could cut to a slo-mo burnout shot. The wheels very clearly are spinning in reverse. It does this both from a stand-still, and also when using the burnout while driving to do a doughnut.
Anyone else run into this? I'll manually reverse the rotation for now.

Ward,
What host application are you using? 3ds Max, CINEMA4D etc? I did a test in Craft Director Studio v9.3.1 using 3ds Max 2010 Design (32-bit) and it's rotating normally for me.

I tried the Burnout in CINEMA 4D and I'm getting some strange rotation so that's probably what you were talking about. We'll look into it and hopefully we can have it sort for the next release (early 2010).

Max 2010
4wheeler ext 9.2.1

I animated everything at 24 fps and it rendered visually fine. Then changed frame rate to 240 for a small segment, which will change the timeline accordingly, I just playback at 24fps for 10x slo-mo effect. When rendered, they definately go backwards. Not just the classic shutter effect of wheels turning backwards. Valve stem goes bckward too.

Thanks for looking into this. I can't verify in 9.3.1 yet as we're having farm issues with it.

What kind of issues are you having with 9.3.1?

Sorry, was out of the office for a few weeks there.
9.3.1 issues are just licensing things with our setup. IT guys have been working with you on that one. Took a screen grab of the curve which definately shows reverse rotation happening. Starts spinning the correct direction, then for some reason goes backwards, then towards the end, goes back to normal.
I'm scaling and moving keys to fix for the time being, but would be a nice one to get fixed.

ThanksImage

Hmm, you're right. I can confirm this in 9.3.1. Unfortunately we're just putting the final touches on 9.4.1 so we will not be able to get a fix for this in time for its release. We'll included it in the next release though. Thank you for reporting this!
