FumeFx Script Properties Questions - Galagast - 11-07-2009

I'm probably having a very cloudy day in head because I can't seem to find these maxscript properties from the fume UI:

Code:
-- using this command on a selected fumefx node

show $

Code:
PreviewStart

PreviewEnd

PrevewNth

PreviewFPS

I tried to get and set thier values, but I didn't notice any change.

SolverType - Galagast - 11-07-2009

This property is also strange:

Code:
SolverType

Usually, if you have a drop down list, if you set the integer for the list to be more than the number of the items, the drop down list would go blank.
For example, Pflow's Position Object location property has 9 items. Executing this code would make it blank.(Index is 0 -based)

Code:
$'Position Object 01'.location = 10

I'm just guessing that the SolverType script access is there but is simply nonfunctional. (Which isn't really a big problem since Conjugate Gradient is the only option we have right now).

ExportRenderingParams - Galagast - 11-07-2009

I also noticed this:

Code:
ExportRenderingParams

There doesn't seem to be any help/info regarding this function in the help files and here in the forums. (I also tried google Big Grin

)

What is this function for?

SystemScale - Galagast - 11-07-2009

By far, this property is the most interesting one as it seems to have a direct effect on the sim.

Pretty simple setup, using 3 identical sim grids (default settings).. the only difference is the systemScale value set via maxscript:

Re: FumeFx Script Properties Questions - superhypersam - 11-07-2009

that last test is interesting.

So would it be possible to have a fume grid at one physical scale ( matching scene geo) but act as if it at another scale Via the maxscript command?

cheers

Re: FumeFx Script Properties Questions - Galagast - 11-07-2009

Yeah, looking at the comparison sims above, the effect probably goes like this:
Smaller Values = Large Scale (Plumes)
Bigger Values = Small Scale (Candle)

The scene above all have 1.5 spacing. My system units is in centimeters.

Here's a larger render:

It would be interesting to do an experiment to see if there are differences when scaling it using these:

Code:
$.scale

$.spacing * scale

$.systemScale

This will export all rendering params, including gradients and TM to a file.
It is here because some companies use their own shaders, or even RMan and with this command they can export
all relevant params.

Hello,

Some params that are visible from MXS and not documented are not officially supported, and/or they're used internally.

Thanks for the info regarding that, I guess it leaves us users to play with it at our own risks. Big Grin

Thanks Johnny! It's feels like a new feature that we could play around with. hehe

I was just wondering, it seems to always return false, even though the file was successfully created.

Code:
$.ExportRenderingParams @"c:\test.txt"

false

Re: FumeFx Script Properties Questions - sitnisati - 11-27-2009

Thanks for you finding - I will check why it always returns false.
