Hello. I have successfully run the demo of ROMP, which exported .fbx file. And currently I want to use the .fbx to control the character. Can you provide steps for the video demo? I can only see the camera one

I tried to use it with simple-romp but it did not work. I already created an issue at the ROMP repository and described my problem here and here in detail.

The author of the ROMP repository answered there:

About live blender driving, please refer to this repo. https://github.com/yanch2116/CharacterDriven-BlenderAddon My colleague is responsible for maintaining this funciton now. Best regard.

and closed the issue.

@yanch2116 So how to solve it?

My goal is to send the positions and quaternions of ROMP (or any other SMPL based solution) over the VMC protocol to other application (not Blender). Any ideas, whats the best way to do it?

Also, I would like to know if there is a way to replace the 3D Character before I run the script and process the video so that I don't have to manually change it every time?

I use ROMP v1.1 on Windows machine. But CDBA works with version 1.0 of ROMP I read installation and using documentation of ROMP v1.0 but i can't figured out all How can i use this addon properly? I'm not good at programming i'm animator and interested in your project. Can you write steps how to install and use ROMP with this addon,please?

I have ROMP driven SMPL model looks OK, but when using CDBA (I using script locally) driven mixamo model, result looks wrong:

I am using this bone mapper in your repo:

bones_mixamo_smpl_mapper = {
    "Hips": "Pelvis",
    "LeftUpLeg": "L_Hip",
    "RightUpLeg": "R_Hip",
    "Spine2": "Spine3",
    "Spine1": "Spine2",
    "Spine": "Spine1",
    "LeftLeg": "L_Knee",
    "RightLeg": "R_Knee",
    "LeftFoot": "L_Ankle",
    "RightFoot": "R_Ankle",
    "LeftToeBase": "L_Foot",
    "RightToeBase": "R_Foot",
    "Neck": "Neck",
    "LeftShoulder": "L_Collar",
    "RightShoulder": "R_Collar",
    "Head": "Head",
    "LeftArm": "L_Shoulder",
    "RightArm": "R_Shoulder",
    "LeftForeArm": "L_Elbow",
    "RightForeArm": "R_Elbow",
    "LeftHand": "L_Wrist",
    "RightHand": "R_Wrist",
    "LeftHandIndex1": "L_Hand",
    "LeftHandMiddle1": "L_Hand",
    "RightHandMiddle1": "R_Hand",
    "RightHandIndex1": "R_Hand",
}
bones_smpl_mixamo_mapper = {v: k for k, v in bones_mixamo_smpl_mapper.items()}
bone_name_from_index_character = {
    k: bones_smpl_mixamo_mapper[v] for k, v in bone_name_from_index.items()
}

Do u know why?

also the hand look not right.

Hey, Yanchxx,

May I ask, what is the output variable, I think "trans" is the translation between camera and object.

What are the poses, is it the location x, y, z, or rotation x, y, z, degrees?

Thank you 👍

@yanch2116 你好，非常酷的工作！我基本把整个项目跑通了，但我有两个问题想进一步请教一下你。　、 １．导入fbx时骨骼的方向错乱了，参见:https://www.bilibili.com/read/cv2520452 。但是这个文章里的方法没有完全解决方向错乱的问题，所以我想请问一下你，你是怎么解决这个问题的呢？ ２．我想请教一下，如何将编辑骨架让其和ｓｍｐｌ的骨架一致呢？ 望不吝赐教！万分感谢！

I found that the avatar will shake drastically when running the webcam demo. And I set the mode =1 to insert keyframe record the webcam results for playback.

Now, if we set one more condition for inserting keyframe, only the frame_idx % 3 == 0 or frame_idx % 5 == 0. This would allow the avatar to move along these keyframes much smoother.

However, is there a way to let the webcam demo runs in real-time using the keyframe strategy I said? This skip keyframe strategy only seems to work with the recorded playback. The character is still moving on each frame when we are actually running in real-time.

Hi, I'm able to run to demo with blender now, but it turns out that the view is locked while the script is running.

If there's a way to enable rotation?

I met the following error while running Beta.blend. I'm using blender 2.83.9. What's the expected version?

Read blend: E:\Workspace\blender_test\addons\CharacterDriven-BlenderAddon-master\blender\Beta.blend 0 meshes freed Error: File written by newer Blender binary (290.0), expect loss of data!

Hey, yanch2116, very impressive job done in visualizing 3D characters. I tested and it works, one question to ask, the code romp_server.py has the setting.show_largest=True, I am thinking, what is the condition with multiple people in the webcamera, when there are many people, the blender character keeps on shifting. Are they ways to solve this? 1, keep on the object tracker in single object_ID 2, visualize multiple 3D characters as input in the camera
