Importing assets has gotten extremely slow for me. If I make a change to one texture and save it, when I switch back to Unity it takes anywhere from 3-6 minutes for that texture to reimport. Same if I apply a change to a texture’s import settings. If I change multiple texture settings, it can take 8-10 minutes for Unity to finish. Same if I change a model, it takes several minutes to reimport. During this time, I can do nothing in Unity, and everything else is slowed to a crawl, so I mostly just wait. According to Activity Monitor, PVRTexTool is using 250-350+ percent of CPU time!
FWIW, I’m running on a Mac Pro (early 2008), Mac OS 10.10.3, with 8 GB of memory, and Unity 5.0.1f1.
Is this normal for Unity now? It used to be I dreaded having to bake a light map because of the down time, now it’s having to make a change in a texture.
