See the instructions in the README: https://github.com/NVlabs/acronym#using-the-full-acronym-dataset You will need to register at www.shapenet.org to download the meshes for ShapeNetSem.

That sounds great! I have very little experience with poetry but read a lot of good things. A PR would be highly welcome!

To understand this better: The feature request would be to provide a function named `get_chain(root, tip)` that returns a list of joint and link names in the order they appear...

Sounds good! Any ideas / expectations on what should constitute an "invalid" URDF? The closest that comes to mind is the ROS specification (which could be extracted from the docs:...

Correct, the following condition is not true: > mesh without UV coordinates, but has a material: should create MTL but no VT This is because https://github.com/mikedh/trimesh/blob/4671ead1432819e8da2f595c4636df429ee3acaf/trimesh/exchange/obj.py#L854 in this case is...

I am also running into the same / similar problem. Here's an example mesh file (it contains two materials, one textured, one non-textured): [original-40.zip](https://github.com/mikedh/trimesh/files/8237074/original-40.zip) Doing ``` s = trimesh.load('original-40.obj') s.export('/tmp/test.obj')...

The same is true for `metadata`, the behavior also changed recently: ``` import trimesh a = trimesh.primitives.Box() a.metadata['foo'] = 'bar' print(a.metadata) print(a.copy().metadata) ``` Output: ``` {'foo': 'bar'} {} ```

Alright, got it, sorry. Will just use "aarxc scene.urdf -s scene.robray" to convert to robray and then add things by hand. Unfortunately, this solution requires to redo these steps every...

I have an articulated object as part of the scene and would like to tag certain parts like handles via the "isa" property. Do you think this is the wrong...

No, URDF is very restricted.
