It would be great to have 2 new Render Elements that would split the smoke into the Multi Scattering component and the Lighting influence component so when using RGB lighting to get individual light control in comp you could also plus the Multi Scattering RE over the top without having to do two passes.
Just to explain it properly, if you had a render with 3 lights (one red, one green and one blue) lighting the smoke with some nice red/yellow/orange fire with Mutil scattering on the Multi Scattering RE would be like the smoke RE but with the 3 lights turned off and the Lighting Only RE would be as if the Multi scattering is turneed off and the 3 lights are turned on.
Plussed together they would be identical to the Smoke RE.

I mentioned this before but now I've had a bit more of a look at it I can see what the issue may be.
Changing Smoke Buoyancy to 2 (or Temp Buoyancy..Fuel Buoyancy seems fine) prints out in the MAXScript listener:
$.SmokeBuoyancy = 2
but setting this property via maxscript does not change anything. You can then query the value $.SmokeBuoyancy and it will return what you have set in maxscript but it will not be reflected in the UI, nor in the sim.
I have had a look through the subanims and it seems setting $.SmokeBuoyancy is setting
$[4][1].Smoke_Buoyancy when it should be setting $[4][3].Smoke_Buoyancy.
It seems that $.Smokebuoyancy is not hooked up to $[4][3].Smoke_Buoyancy properly.
With Temperature Buoyancy $.TemperatureBuoyancy is hooked up to $[4][1].Temperature_Buoyancy, not $[4][4].Temperature_Buoyancy.
The other parameters in the smoke and Temp rollouts seem fine (apart from the vdMultiplier being duplicated so there is no access to the temp vdMultipler).

Hi,

When I render seperate Smoke and Fire passes in 3dsMax 2011 64bit, the alpha channel is the same for both passes!? Is this correct?

If I disable Smoke and render Fire only (and vice versa), I get the correct alpha in the passes which allows more freedom in the comp.

I am confused as to why there is an option to render the elements if the alpha is the same.

Am I a missing a trick here in the comp stage or should the alpha's be different when rendering both smoke and fire together and saving the different elements?

I have searched as much as possible, and have not found an answer here, so apologies if a post exists.

Thanks

Is there a possibility of being able to dial in the influence amount of a spacewarp in a simulation? For example, if I have a gravity spacewarp in my Objects list, it would be nice to have the ability to use a percentage of that force. So if the gravity in my resulting sim looked to heavy, I could simply select the Gravity in the Objects list, and dial it down to say 50% instead of 100%.

I got a situation. I have three PF source, each have its own Position Object node and ABurn node, I got random crash during ABMap calculation, I tried a lot of way debugging it with no success, they crash in different frame number. I can render out each of them separately without problem, so I think maybe the particle count is to much (around 5k), but then I try grouping all three position object into one PF source and adjust accordingly the amount of particles, it render without problem. But of course I lost individual control.

The 3 original particle system and AB setup are very similar, I separated them just for fine tuning things. What is the possible cause of this problem?

Thanks in advanced.

Hi,

Does Afterburn work with Mental Ray? Thanks!

We are having a very big issue with textures getting loaded onto simple sources and object sources.
It seems that if you open up a file, select fumeFX and start simming and you have bitmaps (procedural textures seem fine) on your object sources or simple sources, those bitmaps are passed as being black untill you either view them in the material editor or use maxscript to do something like this:

Hello,

I'm getting a consistent crash with fumefx (2.1b) and 3ds max 2011 64 and 32 bit. The file I'm using is one that fumefx comes with, torus on fire. I'm enclosing the file here. The only thing I've done to it is not render the fire. I can render individual stills, but when I render the stills as an animation (for the purposes of this email I've tried to render them as jpegs), Max crashes part way through the first frame. I've tried using scanline as well as vray 1.5.

Hi,

Does anyone have any idea how to pull off this effect using fumefx?

Hey guys,
I'm working on a pretty complex scene at the moment and I thought about 2 features that would really help me to speed up my workflow.

01. A post "void src", pretty much like culling in krakatoa. Would be awesome to be able to just pick a scene object and every voxel that is inside gets deleted.
02. The ability to constrain the adaptive grid to a specific channel.

I would really love to see this in a future release.

cheers,
Fabian
