> I faced a similar issue as you with no transforms.json file. I had to do a sort of strange workaround, so I'd really appreciate it if someone could give a more straightforward way of doing it, but this is what I did: 1- downloaded the colmap2nerf.py file from [instant-ngp](https://github.com/NVlabs/instant-ngp/tree/master/scripts) 2- saved my colmap outputs (cameras.txt, points3D.txt, and images.txt) to a folder called colmap_text 3- ran the colmap2nerf.py as follows: `python colmap2nerf.py --colmap_matcher exhaustive --text path/to/colmap_text --images path/to/images --aabb_scale 16 --overwrite` 4-moved the transforms.json file that was produced by step 3 into the directory on the same level as your images directory 5- run the training script

Hope this helps!! Hello, I have encountered the same problem, but my COLMAP outputs are in ”bin“ format instead of “txt” format. Is there a solution? Thank you very much.
