Ignoring Smoke Channel?

[petkovic]

Hi guys, i feel so stupid at the moment,

i was doing this dont know how many times, and lately i started getting errors:
Warning: ignoring smoke channel, it does not exist on disk! Turn off the sampling switch for Smoke //

scene is really simple,
- nParticles emitting some particles, then used fume particles source to simulate smoke (velocity is exported).

After sim is done i made a fume particle emitter and hit Play, then in fume particles i turned on Sample Density, and hit Play and the error came

// Warning: Your fume Grid does not have requested data! //

Then i made a particle follow field, and turned on Sample Density and got this error:

Warning: ignoring smoke channel, it does not exist on disk! Turn off the sampling switch for Smoke //

so i know i did this procedure 100x but dont know what went wrong, i have even watched again Allan McKay's tutorial to make sure i do everything right.

-the build is the latest one 3.5.5, could try go few ver back and check if that thing happen in some previous versions.

cheers

p.s.

small update, i just turned Off Density and turned On Velocity sample and so far no errors...
