Max2011 x64 - Krakatoa v1.6.0.43192 Service Pack 1 - September 8th, 2010
Ugh sorry, another one, not really a bug per-se, krakatoa is doing what it is supposed too, when the smoke channel is disabled in a FumeFX simulation, PRT Fumefx does not respect this setting and throws the warning:
WRN: fumefx_particle_istream::load_voxels() - Failed to load some channels from .fxd file "E:\Cache_FumeFX\FumeFX1357943\FumeFX001_0000.fxd"
WRN: The requested channels were: 0xa and the recieved channels were: 0x2
This also causes a fail in the render, respectively.
I wasn’t aware that the smoke channel was still necessary, obviously it is , since you can disable seed in smoke and only have fire.
Fire particles do render when the “Generate Emission from FumeFX Fire” is enabled and Emission is On. Or I pipe a KCM with a vector to emission.
Else
Particles do not render when the above parameter is off, I would expect that they would since the are particles there, in the viewport anyway. I can’t light them, or the old standby force additive mode. Max2010_KRK_FireNoSmoke.zip (22.4 KB)
But Fire particles are purely additive. If there is no Emission, there is nothing to render since Color and Absorption are both black and there is no Alpha generated. You need Emission, one way or another.
Also, in the future please use the word “fail to render” when you get an error message pop up when you try to render that informs you Krakatoa cannot render for some reason. Not getting what you want is not “failing to render”, it is “rendering unexpected results”
, since you can disable seed in smoke and only have fire.
Is there a (KCM) way to make them not purely additive?
