please help, i don't know what happen after i clear cache over 200gb cache, then close VAM. open back VAM then everything went dark now. how to solve this problem?
The cache stores GPU-readable textures and some other files, it does not break scenes in VAM. Using a cache is not mandatory, its purpose is to improve loading times as written in the panel.
If you don't see any lights turned on in any scene, then something's not right in your VAM. Could be:
VAM is in a protected folder and corrupted
A session plugin you're using
GPU driver update fuckery
Corrupted VARs in AddonPackages breaking something
X number of wild guesses
For starters, check your VAM folder location and run a core check (vam_update.exe).
