No noise phase change in animation (AB4.0b) - muzzleburst - 04-11-2009
Hi Kresimir,
Thanks for replying to a previous thread in which I noticed a similar issue:
viewtopic.php?f=1&t=729
I have attached the 3ds Max 2009 scene file that exemplifies the situation.
I set a Turbulent noise phase change for the Low Value and High Value, and did see a change in the noise phase if I performed a render of a single frame (first I moved the time slider to frame 0, rendered, and then moved the time slider to frame 10, rendered: there was a noticeable difference between the two renders). Then, if I did a render using a "Range" from 0 to 10 (under the Common Parameters under Render Setup), there was no change in phase in the frames. I tried the "Frames" option with "0-10", but it also exhibited the same behavior. Active Time Segment also didn't work.
In all failed efforts, I tried writing a MAXScript to render each frame individually.
The following MAXScript made no difference in the rendering (the phase didn't change):
for i = 0 to 10 do
(
render outputfile
"cloud" + i as String + ".jpg") framei))
However, the following MAXScript *did* make a difference (the phase changed each frame):
for i = 0 to 10 do
(
sliderTime = i
render outputfile
"cloud" + i as String + ".jpg"))
I can't imagine what the trouble is, so for now I'm using the manual MAXScript approach to render animations instead of using the normal 3ds Max "Range" or "Active Time Segment" methods.
Can you try to reproduce the animated phase problem on one of your machines with the attached scene file? I am using 3ds Max 2009 (11.0 SP1, 32-bit) Creative Extension on Vista 32-bit, with AfterBurn 4.0b. This is a very awkward behavior.
As a side note, I suspected that AfterBurn wasn't getting the particle age from the pclouds correctly, so I tried setting the particle life directly in AfterBurn, bypassing the particle system's particle life, but that didn't work either (used "Part. Start" and "Part. Life").
Thanks a bunch for any help or insight!!

Hello,
It seems that if you put back visibility of particle systems to 1.0 it renders fine.
Not sure what exactly happens, but it could be some updating problem when particles are
actually 'non-renderable'.

Kresimir

Wow, you're great! Thanks a ton for the help! Changing the visibility to 1 fixed the problem. How awkward.
Cheers!
