Unity amnesia

[PB666]

I finally got Unity to work and produced several parts in KSP.

This is a bizarre problem.

THe problem was my C drive went from being 80% full to 99% full in the process (I have no clue why). So I had to move Unity. I deinstalled and reinstalled the program (latest versions both)

In a much larger drive. The last part I made (a bullet shaped tank) ran hideously slow in KSP. I found a directory with a tremendous number of temporary files.

I installed the 20 part tools and load the 23 tools on top of them.

The blender files are no longer recognized by Unity, not old files that previously worked that it recognized, and now not fairly simple files,. I'm thinking I have to completely scrub Unity from my system, there is some file cached some place that is creating a conflict, but where and how do I fix it?

It did manage to load 1 part, but the part had no texture and when it showed up in KSP is was invisible (it was based on the same blend file previously used).

After that nothing worked.

Has anyone had a similar problem?

UPdate: I removed blender and Unity with about 16GB of space on my SDD. (I found a bunch on Unity files on my Public user directory which I had to manually remove freeing up 4GB of disk space in and above what I previously reported). As soon as I installed Unity on another disk, 4 to 5 GB immediately disappearred. I previously have completely removed anything having to do with Unity from the system, and the unity files are not in the Public User directory, so . . . . . .

Resolved (I hope): Both are reinstalled, I managed to make a test fuel tank amazingly in KSP a pentagon shaped tank can do a SSTO, no accounting for aero, lol. Whatever Unity has added to the C drive, I cannot find, it has not grown from its original state. I suspect what happened in the first place is that Unity overwhelmed the SSD and started glitching out, it probably place a few poison-pill files around that kept it from running properly. By removing everything and changing completely the installation directory, it couldn't find the pills or I removed them.

if you installed Unity 5, it's probably the realtime GI cache that ate up the storage space. by default it can eat up to 10 gigs. Use Unity 4.2.2 for better compatibility with KSP, and not have to worry about running out of disk space because of GI precalculations.

Unity requires FBX plugin for Blender in order to import *.blend files. removing/reinstalling blender probably resolved that issue.
