1. If Unity is opened before you've downloaded the separate assets it deletes the .meta files and you therefore lose any import settings for those files. Maybe tell people to download them before they open Unity
2. Make it clear that the assets have to be placed in the root of Assets. Anywhere else and they won't link to the correct .meta files.

Hi, great work on the project!
I can't seem to find the T-Rex and Triceratops vols either in the repo or the release downloads, so can't get the Mixed reality demo to work.

Are these files included anywhere?

Also, I was wondering if there are any instructions to export volumes from NeRFs made using your NeRF repo?

Thanks

Hi!

I am a student Artificial Intelligence and I am working on a project using NeRF with a group of other students. We are in possession of a dataset that is made by a company we do the project for. The data consists of images such as the one that is attached (but the whole object is visible, right now it is copressed).

We are working with your notebooks and we find them highly useful! Thank you for this contribution.

However, we cannot generate poses. The output of the LLFF script is:

Features extracted
Features matched
Sparse map created
Finished running COLMAP, see /content/drive/My Drive/nerf/kan_new/colmap_output.txt for logs
Post-colmap
Traceback (most recent call last):
  File "imgs2poses.py", line 18, in <module>
    gen_poses(args.scenedir, args.match_type)
  File "/content/LLFF/llff/poses/pose_utils.py", line 274, in gen_poses
    poses, pts3d, perm = load_colmap_data(basedir)
  File "/content/LLFF/llff/poses/pose_utils.py", line 14, in load_colmap_data
    camdata = read_model.read_cameras_binary(camerasfile)
  File "/content/LLFF/llff/poses/colmap_read_model.py", line 115, in read_cameras_binary
    with open(path_to_model_file, "rb") as fid:
FileNotFoundError: [Errno 2] No such file or directory: '/content/drive/My Drive/nerf/kan_new/sparse/0/cameras.bin'

And sometimes we do not have this error but it only says 'no poses could be extracted'.

Here also the output of colmap:
colmap_output(1).txt

Do you know what could've caused this? What can we do better? We really hope to hear from you!

Hi Kwea. How can I convert my own NeRF scenes into the requested volume format? i.e. how to convert .npy to .vol

I imported a model, but there are no shadows. Can you help me with this, thanks
