Particle View won't update on Houdini 12.0.575…on Windows 7 64 bit…
need to toggle the display on and off to see it…feeds fine into a pop merge in the scene view.
Others have this issue? or is it my system or graphic card?
Jim

which graphics card u have

may be u need to update ur gpu driver

i am also working win 7 64 bit only didnt get any prob yet

its a geforce gtx560 which I know is a gamer card but its been pretty rock solid with everything else.

I think it's a known bug (log it again just in case ). Given the low priority of using the deprecated /part hierarchy, I'm not sure how it's going to pan out.

I still suggest a driver update. Im running a 470GTX with the 296.10 driver and things are ok for me. (when I was running the earlier drivers it was horrible, in fact I moved to the beta drivers just to get away from it).

EDIT: Actually iirc I had to switch back to H11 scene renderer. The driver update did help, but didn't stop me getting crashes.
