am using blender 2.72
trying to create smoke… I put in my cube and set it to be the flow… smoke…
added another cube around the other and set it as the domain… my smoke cache is grayed out
and cannot click on 'Bake"
I’ve started a new project, did the quick smoke function … still the cache area is grayed out and
i cannot click on “bake”
I tried 4 times and the area is grayed out...
any idea what is wrong .. I have created smoke before but not working this time
thanks… I just found my answer… oh duh… am learning all this and got stuck and didn’t realize I had to save it first… I was testing it…
do have a question… is there a way to get smoke in the domain to go down instead of up? I watched a tutorial where he did it using a force field and a force wind field, but I can’t get it to work…
In your Domain’s smoke settings, adjust the “Temp. Diff.” value. A positive value makes smoke move up, a negative value makes it go down. With smoke sims (and with most sims of all sorts) there are a dozen ways to do everything, but adjusting the Temp Diff value is a nice universal way to tweak this for smoke.
