basic effector question

[ronald_a]

Hi, I am new to fumefx (maya) and I somehow don't get how effectors work.

I provide a simple test scene that I set up, which should work, but it doesn't. I'm pretty sure I am missing something. If you could point me in the right direction, that would be great.

short description:

geometry emitting (static) smoke and temperature for one frame. temperature buoyancy set to 0. effector running through smoke should set temperature buoyancy to 10 so the smoke rises but nothing happens once the effector runs through the smoke. What am I doing wrong.

fumefx for maya 3.5.7, maya 2015 ext1 sp6


Thanks,

Ronny

Try setting your channel name to be shorter, like a single letter " b " and relink it in the temperature buoyancy controller. (Renaming a channel name in an effector does not update the link in Fume automatically)

For some reason, channel names over a couple letters don't work in Maya Fume.

oh wow, never would have figured that out. that might be a good thing to fix or at least write down somewhere. its funny though, that in the tutorial files (tutorial7_end) the channels are called eff1 and eff2. but there is something broken with those files as well, so that might be the reason.

but anyways, thanks a lot for the help!

Hello,

Thank you for a bug report and a scene.
FumeFX 3.5.8 for Maya will be released tomorrow where you can use normal Effector names.

Great! While you are at it, I'm also having trouble displaying channels like velocity and temperature. They just show up during simulation but not when I scrub through or play back the cache.

Cheers,

Hi Ronny,
velocity and temperature channels are not saved to cache by default. That's why you see them only during simulation.

Search for Output rollout in Attribute Editor when FumeFX is selected. You can find there two checkboxes named "Export Temperature" and "Export Velocity". Try to check them and see if it works.

Ah, yes of course. I actually thought I had them on.

Hi,
I'm glad it works now.
