i have a tip & Trick for all who think their Baking is very slow they don’t know why.
There are two Points what you have to pay attention on.
The Higher the Render Samples are, the longer the Baking. Higher Samples like 500 Samples in my Project took around 1 hour to Bake.
1 Sample only a few Seconds.
Samples low = low Texture Quality (But not bad) less time (Hurray)
Samples high = high Texture Quality (Hurray) LOOOONG TIME (That’s really bad)
if you checked in that you Render with your GPU. Set the Tiles to a high x & y Value like 256 that is giving you a Time Boost.
If you use Only CPU set the value to a lower number like 32x32.
Sorry for my English, it’s not my first Language.
Best Wishes and Happy Baking.
