fbx-python problem #8

Closed Andyen512 closed 1 year ago

Hi, I met an error about fbx-python, do you know how to solve it? /SMPL-to-FBX/FbxReadWriter.py", line 35, in init raise Exception("An error occured while loading the scene :(") Exception: An error occured while loading the scene :(

Hey I am able to to convert the example pkl file into fbx using this: python3 Convert.py --input_pkl_base <pkl_path> --fbx_source_path <fbx_path>/SMPL_m_unityDoubleBlends_lbs_10_scale5_207_v1.0.0.fbx --output_base <output_path>. Please provide details (step by step) to replicate your issue.

Make sure that fbx_source_path includes the total path of the fbx model file including the file itself, i.e. it ends with ".fbx"

thx, the problem is solved. And another question, if I use some SMPL estimation methods like VIBE or ROMP to get the SMPL parameter, Can I ues your method to modify the SMPL format like AIST++ to convert SMPL to fbx?

I haven't tried their methods, you may need to figure it out.

So this repo is sort of specifically designed to convert the SMPL representation in AIST++ dataset to fbx. For any other projects that use the SMPL representation, as long as they use, or you can figure out the way to convert their SMPL representation to AIST++'s (24 joints axis-angle rotation, and mind the joint order!) and put them into pkl files, then there's a chance that this repo could work.

I think in ROMP's publication, they mentioned something about Instead of using the full 24 joints of the original SMPL model, we drop the last two hand joints. You may need to figure out what's going on and is there a way to convert their SMPL into AIST++'s SMPL.

By the way, I think both ROMP and VIBE provide python scripts to convert their predicted results into fbx, maybe give it a try?
