Hello, thanks for this work it's great !! For my project, I wanted to test the lidar sim functionality. I am running into some issues, seems like some resource files related to Lidar aren't pushed, which seems to be causing the issue. the error I am getting. self.avg_mask = np.load(str(rsrc_path / "Lidar/avg_mask2.npy")) File "/home/amohan/python_env/vista_env/lib/python3.8/site-packages/numpy/lib/npyio.py", line 390, in load fid = stack.enter_context(open(os_fspath(file), "rb")) FileNotFoundError: [Errno 2] No such file or directory: '/home/amohan/python_env/vista_env/lib/python3.8/site-packages/vista/resources/Lidar/avg_mask2.npy'

As you can see from the LidarSynthetisis code it requires some files image kindly push or provide a way to download those files if they already exist point me towards them. Thanks in advance.

agree, I see the same issue @zswang666 these files should be in the vista python package as I understood!? @aamini in the resources folder you've added the Lidar folder and the Lidar.tar.gz file - where can we download these files?

Hi, has there been any updates on this issue? I am unable to spawn the lidar because of the missing avg_mask2.npy file

Hi all, I am also interesting in using the lidar feature but cannot find the lidar files under resources. Is there some other source we can refer to to get these lidar resource files?
