hey all,

I was using paint FX the other day, just messing around with it on a 2D canvas, I noticed that some of those brushes are slow as all he!! to update. Whats the deal? I'm running an Nvidia Quadro 4 900XGL, 3.5gigs of ram and a dual 1.8ghz athlon...and it makes my system grind almost to a hault :thumbsdow The waterfall brush is one of the slower ones. Is paint FX just that slow, (I hope not) or is something wrong?

Thanks for any help on this one

Yeah, like alot of things in Maya, PaintFX is generally super-slow. Hopefully, alias/wavefront will optimizes this and the other slow-ass features. :-)

Maybe its your drivers. Works fine here on a gf2mx.

I'll give it a shot and see where it gets me, I thought it may be my drivers as well beaker, but I have the A|W approved ones...beats me.

There was a problem with some graphics cards where the update event waits until a certain amount of pixels have been drawn. If this is the problem you will notice that painting is faster if you slightly zoom in or out of the canvas( alt-leftmouse drag). If this is indeed your problem, you can set the following environment variable, which forces the paint effects and render windows to use textured triangles rather than raster fills when in 1:1 aspect:
setenv MAYA_SLOW_DRAWPIXELS 1
