there is a way it can work

if I remember right the timeshift wont work on something coming through the fetch input block begin but if it comes into the blob this way it’s ok

“`vlength(vtorigin(“.”, “../YOUR_FOCUS_OBJECT_HERE/”))“`

that’s how ud do it

Hey chaps, handy little snippet which you may already be aware of to find the closest point that is not self: `int nearpt = nearpoints(0, @P, 1e34, 2)[1:][0];`

i did a little write-up on how to roll your own VEXpressions using Python: www.toadstorm.com/blog/?p=595

Quick tip: hold down middle mouse button on any color parameter, you can sample any pixel’s color on your whole screen even outside Houdini, cross platform!

maybe I am the last one who learned this 😅

Here is Rich Lord’s awesome Vex/Vop math hip. Great for learning the ins and outs of orientation, quaternions, dihedral, etc: http://richardlord.tumblr.com/post/159277887181/ive-started-collecting-a-bunch-of-tricks-i-use-a

probalby grab it from there instead since I mightve made modifications by mistake

and if u have multiple chunks you want to do individually with like a class attribute
`@P -= getbbox_center(0, itoa(@class));`

ugh, my brain is mush tonight… whats the node to convert groups back to attributes, like a connectivity sop?

i’ve selected polys, given them random colours, partition to make them groups, now i want the groups back to attribs

hmm, or vex this and define my own attribs via hsv…

yeah that worked, woo

well goddamn, someone mentioned this at work today, just tried it

“`setprimintrinsic(0,’pointinstancetransform’,@primnum,1);“`

do that on packed prims, orient will now rotate them automatically, no bollocks of having to manually update intrinsic transforms

right on

WIP HDA Versioning Script gist.github.com/chris-gardner/4c746dbfa182aaaf070b52bf1e7a98ec

i’ve included the OpMenu.xml stuff needed to make it all right-clickey

object merge in the camera/camOrigin sop into your network

using transform ‘into this object’ in the object merge

there you get a single point representing the camera

so you can just v@camdir = v@P – point(1, “P”, 0);
