Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Datasmith 4.22 - improper rotation of imported animated camera

Hello, I am trying out Datasmith 4.22 with a simple scene from 3DsMax 2019 containing a few primitive objects and an animated camera. Everything imports via datasmith OK except for the camera roll and Yaw.

The Roll is 89.9999924 (should be zero) easy to fix as only two keyframes The Yaw is keyframed every frame from 0 to 100 and needs offsetting by -90deg.

Linking to an empty actor which is aligned to camera, in order to rotate the camera, doesn’t work. The camera flies off somewhere else.

Perhaps i've missed an orientation or Z-up checkbox somewhere? Feels like a bug though, I hope I'm wrong!

Thanks Graham

Product Version: UE 4.22

Thank you, Jeff.

Bug report submitted.

In the meantime I will create a rotation offset in Max just for export, unless there is a quick fix in Unreal?

Thanks Graham

Extra information:

I noticed that the just after importing the Datasmith file into Unreal, all the cameras are actually correctly oriented.

But, when I double click on the Datasmith created "Level sequence" asset in the Datasmith's animations folder, all the animated cameras suddenly get offset in rotation. This offset is NOT undo-able. If I make my own "Level sequence" asset and load the cameras in manually they have no animation.

I tried linking my Cameras in 3dsMax to a point helper and only animating the helper, but the result is the same in Unreal after entering the "Level sequence" asset.

Interestingly, I have a teapot with animated rotation (included in the Datasmith import from 3dsMax), which is not effected at all when entering the "Level sequence" asset.

I hope this info can be of use. (I can't see the bug report I submitted listed publicly yet, so I can't update it with the above.)

Thanks Graham
