Sean-R started following Glue constraint warning - "Required data Glue not found or the wrong type.", [q] for each node, How to separate lines into different colors? and and 7 others

You are pointing to the incorrect level, try: `point("../foreach_begin1", @ptnum, "pt_id1", 0)` and centroid("../foreach_begin1", D_X) centroid("../foreach_begin1", D_Y) centroid("../foreach_begin1", D_Z) Also, your foreach_begin Method needs to be set to "Fetch Piece or Point Thanks, Sean

How to separate lines into different colors?
Sean-R replied to pkkk's topic in General Houdini Questions
The each line produced from the findshortestpath SOP will be 1 single primitive. If you set the color node to Primitive and then random each line will a separate colour. -
Hi Johannes, There doesn't seem to be an exact way (at least not that I can see). But there are a couple of parameters you can change to roughly achieve this: Minimum volume: Anything below this threshold wont fracture and you can calculate the fractured pieces volume in a wrangle. Points by area: By lowering this value you control the amount of fractures. Less fractures, the bigger the pieces. Maximum Fractures: Increase this number to keep fracturing the RBD object until all pieces have fractured to their smallest size. Hope this helps!

Hi Olly! Hit "D" in the viewport to bring up the Display Options, go to the Guide tab and you will see a parameter called "Guide Font" Thanks, Sean

You need to define your velocity. If you add the following line to your wrangle it will work: v@v = @N; You will also need to reset the Inherit attributes parameter back to "*"

Hi Michal, I put an "*" in the Pin Points parameter to include all the points and set Pin Type to Soft. The pigs now follow the animation and interact with each other. issue_fixed.hipnc

Have you tried fit($FF, 1, 600, 1, 100)

Glue constraint warning - "Required data Glue not found or the wrong type."
Sean-R replied to hotdoggyurkeyam's topic in General Houdini Questions
Huh, strang. At least it sorted itself out! -
Glue constraint warning - "Required data Glue not found or the wrong type."
Sean-R replied to hotdoggyurkeyam's topic in General Houdini Questions
Looks like you're missing the constraint_type attribute. Try this in a primitive wrangle: s@constraint_type = "all"; -
How are you referencing or isolating your primitive number? If you want to isolate the left shoe using the path, you can use @path=="leftShoe" in the group parameter of a blast node. In an if statement you could do something like this: if(s@path != "leftShoe"){ removepoint(0, @ptnum); } If you really want to go the string array route maybe the strmatch() function will help?

Are you trying to set the third element of windvelocity? If so, give this a try: if(@Time > 2.8){ windvelocity.z = -2; }
-
Hi Matt, It looks like it's an order of operations thing. If you wrap @P2-@P in brackets it seems to work fine
-
Try a for-each point or for-each primitive depending on the attribute type, then enable "Piece Attribute"
-
You don't need to use a foreach. Look into wedging: http://www.sidefx.com/docs/houdini/nodes/out/wedge.html
-
To put the vertices in an array attribute: i[]@prim_vertices = primvertices(0, @primnum); You have to declare @prim _vertices as an array. You don't need the first line of your code, that would declare a variable. Unless that's what you want of course
