Here is the link for the new users that are asking how to do this. Did the videos some while ago, but always worked for me.

Good post, some of the first videos covering this topic.

Nice one BOTR!
It should go to the tutorial section. imho
Personally I prefer to work with makehuman chars.

since I made these videos (2016 I think), I usually now just upload an OBJ file to The Mixamo rigger and then apply animations to it., download it and import into GG using a GG default character FPE and modifying. all very easy

if I'll send tou you a character i had issue to correcly import could you create a video with the complete pipeline for import it?

i have problem not with the import itself but with the correct apply of animations to character behaviour..

@Bored of the Rings. Recently tried myself and yes it works great now, the fbx importer is a lot better than it used to be. No converting beyond the bare minimum Much better!

Yes is a lot easier now.
@JC leon - sure , feel free to send me your model and I will try and find some time to do a video before I go on holiday

thanks i sent you a pm

@JC LEON: got US MArine finally into Classic and MAx, although in classic the main texture UVs are incorrect at the moment. Anims work fine. I will fine tune. Need to remove the weapon attachment me thinks. FPE will need modifying for the various anim frames.
Classic:

MAx:

@JC LEON: imported the US MArine ok now , although scaling needs to be applied. Anims work ok. well that was fun.

@ BotR ,,hi andmany thanks .. did you register or documented the process so me and we all can study and learn something form this??

A video will be on it's way as soon as I can do one. You will need Autodesk 3ds max and kwporter Directx exporter plugin.

these are the characters from 3drt not mixamo, but the workflow is the same for both yea?

Yes, they are similar, I have videos for the Mixamo chars under third party section which involves renaming the bones. The initial decision users need to make are:

0. What are the tools I need to do the job perfectly? a lot of 3rd party progams are not great when e.g. exporting to directX format
-these days I find that the FBX2GG just bombs out when trying to import anims, it's easier for me to use 3dS max and export to directX if I want to use the original model anims.
0a. what format do I want to export to e.g. directX, FBX, OBJ etc.
1. Are there any meshes/bones that need removing e.g. a weapon
2. Am I using the animations from the original model or using GameGuru anims or e.g. Mixamo or another package animations
2a. using a program like mender tends to correct any .X files and imports into GG classic no problem otherwise sometimes you can get disfiguration. I can upload if need be as it was always free. and/or if you have it or can get a copy get microsoft directx meshview.exe (or mview.exe). I can also upload if need be.
3. Fragmotion is a good tool for manipulation e.g. deleting bones from the hierarchy e.g. weapon, also adding the required FIRESPOT bone and setting the correct rotations for it. it is also a good idea to zero the bone rotations. In FM, you can also append animations.
FM does not import FBX at all, you will always get an error. The DBO export is not always great either.

I will add any thing else I can think of here and do a general process video when I get the chance. I have a 2 year old that needs a lot of focus at the moment.

If you want to use the Mixamo auto-rigger, this is a really good way of taking an OBJ or FBX char and getting it rigged and then downloading animations and adding them to the auto rigged character.

It all depends on what you are trying to achieve.

That's why he removed it in FM 1.3, he just couldn't get it to work properly.

FM 1.3.2 does import some fbx files

1.3.2 doesn't import fbx at all, the option was removed, only 1.2 has fbx import and it's dodgy.

1.3.3-1.3.6 dont open fbx
