"None" animation compression algorithm not respected on re-import

Two bugs I’d like to report. First:

  • Open an Anim Sequence
  • Change “Compression Scheme” to “None”
  • Re-Import Anim Sequence
  • Observe Compression Scheme: it will no longer be “None”, but instead will be either your default compression scheme, or in the case you have “None” as your default compression scheme, it will be “Anim Compress Bitwise Compress Only”

Expected Behavior: If you have set a compression scheme of “None” on your Anim Sequence, it will be preserved during re-import

Bug 2)

  • Edit → Project Settings
  • Select “Animation” tab under “Engine Settings”
  • Change “Default Compression Algorithm” to “None”
  • Close Settings
  • Import a new Anim Sequence
  • Open Anim Sequence, and observe “Compression Scheme:” - it will be “Anim Compress Bitwise Compress Only”

Expected Behavior: If you set “None” as your default compression algorithm, new anim sequences imported from FBX files will use “None” compression scheme

Hi RiotSamC,

I was able to reproduce your first bug in 4.12 (your product version lists 4.11). It is entered as UE-31957.

The second issue is entered as UE-31958.

Thanks for the thorough repro steps.

Hi ,

Do you have some news about the anim compress issue?

We have this problem too.

Where can I change on ue4 source code? Con you orient me please?

Hi Sebastian,

These are still on the to-do list, but mainly to remove the “None” option. It doesn’t actually do anything, but instead keeps the last compression that you set. We do not actually support uncompressed animation data.

What is the status now? Still not supported?
