rjshae Posted March 13, 2017 Posted March 13, 2017 It looks like you're making nice progress. This'll be great if you can get it working.
FreshLook Posted March 22, 2017 Author Posted March 22, 2017 I achieved converting a gr2 skeleton to a FBX skeleton. When imported in Blender looks like this: http://i.imgur.com/rhrh8RH.png Now I'm going to investigate gr2 animations.
FreshLook Posted April 7, 2017 Author Posted April 7, 2017 (edited) I achieved decoding all the data from several gr2 animation files. There's data that I don't know its meaning yet: - Vector Tracks: I don't know what this is used for and when I look at the data it looks like garbage.- Transform LOD errors: I think NWN2 uses LOD for skins but not for skeletons, and the data looks like garbage anyway.- Position, Orientation and Scale-Shear of bones: This is the data that seems relevant and I think I understand it. The data makes sense to me. I will try to visualize an animation. Edited April 7, 2017 by FreshLook
Snowmane72 Posted April 7, 2017 Posted April 7, 2017 @FreshLook I am very lucky to have stumbled across this thread because I was just about to embark on this same path. My particular use case is to import MDB/GR2 into the Amazon Lumberyard game engine (which supports FBX). Do you have the source for this converter on github or some other repository? Do you need/want help with the development? It looks like your pretty darn close to having this complete, but I'd love to help in anyway possible.
FreshLook Posted April 7, 2017 Author Posted April 7, 2017 Greetings @Snowmane72, I'm in the phase of investigating the GR2 file format in depth and writing quick and dirty code to solve all the unknowns as early as possible so I can continue with the confidence that I'll be able to achieve all the goals. At this stage I'm not sure how you could help me and the code isn't in a state that is ready to share yet. In a next phase I would release code and binaries and then I could get help even if it's just testing.
Snowmane72 Posted April 8, 2017 Posted April 8, 2017 Sounds good. I'll keep an eye on this thread and let me know when/if you get to that point.
4760 Posted April 8, 2017 Posted April 8, 2017 I achieved decoding all the data from several gr2 animation files. [...] I will try to visualize an animation.Great news! But do you mean *_skel.gr2 files (the ones defining the creatures' skeletons, as in post #13), or all gr2 files? (meaning in that case we won't need to have 3ds max 8 and the Expotron plugin to be able to create new animations) I'll sure keep on checking this thread regularly.

(meaning in that case we won't need to have 3ds max 8 and the Expotron plugin to be able to create new animations) I'll sure keep on checking this thread regularly. I mean gr2 files that contain an animation like P_HHM_UnA_idle.gr2. As far as I know, NWN2 has gr2 files that only contain a skeleton and gr2 files that only contain an animation. I already decoded and converted to FBX a gr2 with a skeleton (post #13 was P_HHM_skel.gr2). Now I decoded gr2 files with animations. The next milestone is to dump an animation to a FBX and visualize it like I did with a skeleton. So I think I'm able to decode all gr2 files (though I will need more tests). Until I'm not able to generate gr2 files and get them working in NWN2 I can't guarantee an alternative to Exportron. I'm focused in investigating the gr2 format so I can announce as a soon as possible that an alternative is possible.
