FBX Settings Motion Range Problems

Hi @REDACTEDUSER

If you have multiple characters in a single animation file, you will need to define different Actors in the Actors tab, and then make sure you have the correct root joint selected in the "Select root bone" field of the Motions for that character.

Please note also that any FBX file processed by the engine will have a .ASSETINFO file saved alongside it (same name as the FBX file but with the .ASSETINFO suffix) so that any information like the creation of multiple separate animations from a single FBX will be saved with the FBX - something to note if you are using any form of source control on your project.

I am not sure how you would expect FBX to "know" about your separate animations from your source file - is there a method in particular that you are using in your source file that you would expect to be translated into the FBX format and read by the game engine? Thank you for any more information you can give us - we are always trying to understand the needs of our customers and how to make Lumberyard better!

Hi @REDACTEDUSER

1. Which version of the engine are you using?

2. What software was used to generate the FBX files?

3. Which version of FBX was used, and whether the FBX is ASCII or binary

4. Did you bake animation onto your Actor skeleton, or is your animation still on the rig?

Thanks!

I'm using version 1.12.0.1 Build 532502.

I've tried now with several different FBX files exported from both Blender and Max, and various versions of FBX. 7.4 binary and 6.1 ASCII are two versions I can verify, there may be others mixed in. All FBX files I've tried to import have the same issues:

1. If the FBX file contains multiple separate animations only a single animation is picked up by Lumberyard.

2. If the FBX file contains a single track with the animations placed in at specific frame ranges, only a subset of the total frames is pulled out.

Are multiple animations in an FBX just not supported?

Thanks for the reply. I don't expect the importer to know anything about the animations, like I described in the original post I've already done exactly as you said. And like I said, the FBX Settings throws an error saying there are only 81 frames available in the FBX, when there are actually a few thousand frames. I've tried with about a dozen different FBX files and it's always the same.

I can import these same FBX files into Unity, and set up all of the animations based on frame ranges without issue.

Sorry I'm not sure if the original file I've tried has it baked. When I exported a couple FBX files from Blender I had the baked animation box checked tho, and these behaved the same way as my original file with the FBX Settings. Not sure if it's any help but I uploaded one of the FBX files I was testing with, which has 15 animations.

For example, the FBX used in the images above. There are 39 seconds of animation in that file. Both Unity and Open 3D Model Viewer have no issues loading and splitting the animations, but the FBX Importer in Lumberyard thinks there are only 34 frames.

The spider FBX I attached has the animations already split up in the FBX instead of using a single track for all the anims, and the result is still the same. In Lumberyard It's not possible to load an FBX that contains multiple animations and use the Motion Range or anything else with the FBX Settings to split them up.

We'll just work around this and export one FBX per animation.

I can see some animation, but it would be difficult to debug the animation before you determine what the issue is with the initial character setup.

Our documentation on basic character setup is still in transition from the legacy system, and will updated soon.

Also - side note - it looks like your original animation file was created at 24 FPS, while the Lumberyard game engine runs at 30 FPS. You may want to adjust your source files to be 30 FPS and recreate your FBX files from those so that you have WYSIWYG between source and game files.

Hey @REDACTEDUSER

Cheers :)

@REDACTEDUSER

No problem @REDACTEDUSER

Does anyone know if amazon haves plans to add "takes" to the FBX importer? took me forever to figure out this is why my other animations were not loading in lol.
