Hello everyone.
Yesterday I had the good surprise to discover 'Akeytsu' on this website
https://www.nukeygara.com/.
It is a nice 3D animation software.
Currently its developers are offering to everyone for free a ' ex-educational license' valid 1 year, fully featured.
I read their EULA and I noticed that it would be advisable to place a reminder in your agenda at a date situated at a few days before the end of the license (see screen capture #1) if that special offer is not renewed by that software house.
Therefore you could refuse an automatic renewal of the license for which you would have to pay some unexpected price.
Nevertheless having personally tested several 3D animation software during the last years I may say that 'Akeytsu' is a good software with a user-friendly interface.
It took me a big hour to examine the major tools of that application.
I show here a rapid test with which I imported a free avatar (rigged FBX format) and a free animation (BVH format) that I previously downloaded from this website :

My workflow inside 'Akeytsu' was not difficult. I intuitively discover how to create that combination (rigged FBX + BVH animation) which is not so easy - or impossible - to create with some other 3D animation software :
1) Import of the rigged FBX avatar ( my choice : Frankenstein)
2) Import of some animation in BVH format (my choice : topickup)
3) In the pane 'Anim Bank' I selected the tool 'Retarget Animations'
4) in the next popup window relative to that tool, I selected the source 'topickup' and the target 'Frankenstein'
5) and I could see that the transfer of the animation was successful on my selected avatar
6) I exported that animated avatar in FBX format (textures not encapsulated in that file, but saved in a separated folder)
7) I transferred the FBX file into the texture folder.
8) I imported the single diffuse/color texture atlas in the free open source software 'Materialize' downloaded from this website
http://boundingboxsoftware.com/materialize/ and the required maps were created by this software to be able to generate a PBR material for that asset.
9) The textured animated avatar was imported in GameGuru MAX with its asset importer in FBX format and the process was successful after a few adjustments (size = 40, collision = polygon, adjustment of the materials to obtain the desired rendering).
10) Animated avatar tested successfully in a level (no behavior applied to that asset) of GameGuru MAX (Steam version Build 2023.08.06).
Here are a few screen shots relative to my experiment :
