Hey Houdini Wizards,

Like many of you I am jumping on the attribwrangle bandwagon. The presets thread is a pure gold mine that I enjoy learning from.

I am curious about other tips people have for integrating wrangles into their workflow. In particular, I find myself with a zillion new point attributes hanging around that I may or may not remember to delete. This has the knock off effect of ballooning my disk space usage.

getbbox(v@min, v@max);
v@center = (@min+@max)/2;
v@v = (@P - @center) * ch('mult');

This script alone has added 4 vectors to my network, when I really only wanted 1.

How are people dealing w/ this, any chance there are some slick tricks the houdini wizards have come up with? And really, what else is awesome about wrangle nodes that people have found??

thanks!

If you don't want to create attributes, just do:


vector min, max;
getbbox(min, max);
vector center = (min+max)/2;
v@v = (@P - center) * ch('mult');

That's great, Cameron!

Are there any other implied differences to using vector vs. v@ ?

Thanks!

The magic of his code isn't using vector vs. v@
The key is that he removed the @.
This just creates local variables and not actual attributes.
As you discovered, it avoids creating additional attributes, and it's also more forgiving of default values.
