CGTalk - PaintFx Animation

Hi,

Wondering if anyone could point me in the right direction...

I'm doing a very simple animation using a pre built brush (white Pen). The Scene involves a map with various strokes connecting the different places. I animate the stroke using flow animation, and everything is fine in the view port, however initial test renders show that the animated is different from what is displayed in the viewport, ie, on an animation of 1 to 500 frames, the painfx grows only a tiney amount along the curve, where as the viewport displays the paintfx growing along the entire curve during the 500 frame animation....

The setting for the brush are default for the White Pen brush except for the following:

Under Flow animation:
Flowspeed: 1
Texture Flow : Enabled
Stroke Time: Enabled
Time Clip: Enabled

Start time: 5 Seconds
End time: 20 Seconds

Under Stroke Tab
Sample Density : 5 (to provide smooth animation - not segmented)

Non of these attributes affect the render, nor do any other settings as far as I know...

If anyone has any Ideas, please let me know... Very odd to see something render completely different from what is seen in the view port...

Thanks in advance,

Jamie.

You must be using 7.0. There seems to be a bug with the new pfx mesh draw in terms of correct display of flow speed when tube is off.
If you convert pfx to poly the result will show the correct value. After adjusting your animation you could delete the resulting output mesh and turn on visibility on the stroke( to render as pfx instead of poly).

Note that the start end time refers to "emission" time, not bounds to complete the flow. The tubes will start emitting at the start time and move forward at the flowspeed. The motion will be slower if you have a higher sample density and if the cvs are closer together. When the endframe is reached the base will stop emitting and the tube will appear to shrink from the base.

Cheers Duncan,

converting to polys worked a treat!

On another note, does anyone know how to install new fonts for Maya "create text" tool. The help has left out instructions on how to do this (it says it will tell you but forgets too)

I've installed new fonts to c:\windows\fonts\ and rebooted the computer\Maya, however they don't show up.

Any help would be great,

thanks in advance!

Jamie.
