HI,

after being at the Roadshow I wanted to see what the FlowField SOP was ment to be … (C.o.r.e. guys talked about it if I'm not wrong)… but unlucky I simply cant add it to my SOP network… once i TAB->flowfiel-> enter (to put it on my net) Houdini just crashes…

here's the output of my /tmp crash log:

here a cropped output with “# strace houdini”


let me know if you need an entire log

any idea?

Hi Jean-Claude,

I tried, but couldn't reproduce this problem. Could you maybe send a hip file with instructions to support@sidefx.com?

Thanks,

Joe

hip file?.. empty scene here… houdini fired up .. and trying to get a flowfieldSOP and read the manual … and it crashed…..

H81_704, FC4
works just fine…
although there is no help card

Since the FlowField SOP is part of the proto_install you need to make sure you reinstall the FlowField SOP whenever you upgrade your build of Houdini.

Try rerunning the proto_install with your current build and see if it still gives you trouble.

You obviously have installed this non-supported SOP from a previous build/release and may not work properly with the current build you have.

Try completely removing the .dll/.dso and re-install the flowfield SOP using the proto_install command.

oh oh … yeah.. it was the old release still installed… thanks a lot guys.

that said… is there an automatic way to reinstall proto_stuffs when upgrading houdini?… i can make a script for that easly…. but isnt there a way houdini just rewrite/reinstall (maybe and installer option?) the proto_stuff? maybe that's a RFE… but I find such RFE makes sense overall.. dont you?

cheers and thanks again.

Because it's not officially part of the install - they are prototypes - I think it makes sense to let the user control what gets installed, especially when the proto-installs tend to get installed outside of the usual $HFS tree.

Cheers,

J.C.

that makes sense… thanks

cheers.
