this is neat, in H17 they added the cute lil function: `polyneighbours()` so you scrubs dont have to use half edges anymore

`hou.Node.type().name()` returns name of type of given node

best way to find all instances of given node it’s hou.NodeType instances

so eg to find all instances of mantra node: “`python hou.nodeType(hou.ropNodeTypeCategory(), ‘ifd’).instances() “`

other useful thing about searching nodes is that we have access to build in search framework(one that appears after ctr+f)

it’s in the packages called nodesearch at `$HFS/houdini/python2.7libs/nodesearch`

what a cool way to do curve sag:) thanks for the idea

i used to do a three point curve, move the middle point (point 1) down with a transform, and then do a convert to nurbs and resample. This however has a lot fewer steps

funnnn

the hip file if someone wants it

or use the binding options in the second tab of the wrangle

you can refer to a generic “myAttrib” in your code, but bind it based on a variable defined with `chs(“attribName”)`

cool, let us know what you find

in other news, finally finished this:

Yon recently posted a link to a .rar file with example models for destruction practice. A few of them contained a bunch of related texture maps referenced by a .mtl file.
I wrote a short script that will read the .mtl file and create a Redshift material with a *rsTextureMap* populated with the associated map for that material. It is a quick way to get a bunch of materials generated that are related to the model.
You can check it out at this link if you are a Redshift user. forums.odforce.net/topic/32900-mtl-to-redshift-material/

guys, I collected couple of VEX snippets and put them on one place

feel free to check it, hope it will be useful

I am trying to create a nice reference page where people can quickly look stuff up, without browsing all around the web 😃

let me know what you think about it

“`int pp0[] = primpoints(0, 0);
vector prpos = prim(0, “P”, 0);
vector pos0 = point(0, “P”, pp0[0]); vector pos1 = point(0, “P”, pp0[1]); vector pos2 = point(0, “P”, pp0[-1]);
vector v0 = normalize(pos2-pos0); vector v1 = normalize(pos1-pos0); vector v2 = normalize(cross(v0,v1)); v1 = normalize(cross(v2,v0));
matrix x0 = maketransform(v1, v2, prpos);
pp0 = primpoints(1, 0);
prpos = prim(1, “P”, 0);
pos0 = point(1, “P”, pp0[0]); pos1 = point(1, “P”, pp0[1]); pos2 = point(1, “P”, pp0[-1]);
v0 = normalize(pos2-pos0); v1 = normalize(pos1-pos0); v2 = normalize(cross(v0,v1)); v1 = normalize(cross(v2,v0));
matrix x1 = maketransform(v1, v2, prpos);
matrix output = invert(x0)*x1; @P *= output; “`

i think it’s that
