Missing csv files about niagara_study

[DarknessFX]

Unfortunately I don't have the original CSV or HCSV files that you mentioned:

For csv_content_example files, they came from UE4 ContentExamples project, but they are already converted as .uasset files and I migrated them to this project.
For Stanford_Bunny files, you can find it at http://graphics.stanford.edu/data/3Dscanrep/ . I don't remember exactly but I think I used some online tool to convert PLY to CSV and then just renamed the extension to HCSV, after imported to UE4 I deleted the original files. :/

Not everything is bad news, there are 2 HCSV raw files on the project, you can find them at:
\Content\VFX\DepthScanning\Test.hcsv
\Content\VFX\HCSV\Trimble.hcsv
