This is a clever way to do it, after taking a nap it seems so obvious! Thank you - let me see if I can add something else here for others in the future who face this problem!

I was just trying this same exact thing today, I ended up having to build my own pyro-spread in vex.

Taking a look! And thank you, The idea is to copy for example a sphere to each point, but have the sphere exist for only one frame so that I might use it to emit RBD

I have a line a point that is animated, and over time they are added inside a group based on criteria. I'd like to store the frame at which the point is first added to the group, and delete this point. It seems so simple, and frankly embarrassing I can't solve easily - I have tried solvers or perhaps hardcode an age to the points.. but no luck! delete.hiplc

Hi Oddforce, I've been struggling with what I think should be a 'simple,' RBD problem. However, it's worth exploring and could not find any solutions through usual research. I came across this effect by Mykolas and it appears that there is a based deforming geometry followed by a fracture, I also cannot detect any 'switch,' of geometry. Therefore it is safe to assume it is all been processed inside on solver. lerp_oddforce.mp4 fracture_oddforce.mp4

Which render engine are you using? If Redshift you can use OSL: https://github.com/redshift3d/RedshiftOSLShaders/blob/main/Iridescence.osl

Hello, I need a way to fracture GEO recursively/dynamically using the RBD material facture (No clipping, or cut); (I have built and seen methods for splitting boxes using a loop inside an SOP solver inside a DOP, but have not seen a version using RBD material fracture or the new RBD bullet solver sop) Here I have a basic setup with gravity and rocks crumbling, I've added an attribute transfer to visualize a green zone in the middle. The goal is to say, at frame 120 (Or any random frames) for anything that's green or inside a threshold to split into new parts dynamically while retaining the settings of rbd material fracture if possible. Rocks in green 'split into new rbd material fractures,' rocks without color remain RBD but do not split. Ideally with the RBD bullet sop solver, no DOP network approach. procedural_fracture.hipnc

Very nice :)!

Getting the ID, is not problem. However I can't get the ID to equal a string: for example: "if(@id == 1) { v@Cd = set(0,1,0); s@stringAttrib = "hello world"; }"

Hi everyone today I have a simple problem that I don't have the experience working with text in Houdini to Solve, 1. I've created a grid, randomly selected a couple points using a group. I then fed this group to a copy to points. 2. The group of points being copied too are being enumerated so that they have an unique ID. 3. The font is entering the loop, receiving the ID and now displaying it's ID number. 4. Desired result: Per unique ID, I need to be able to say 'if id = 0, then text = 'apple,' just as a random example. I will of course also use the ID number to delete or blast things down the pipeline. Thank you in advance. File: uniquetext.hipnc uniquetext.hipnc

Ah, I had played with the inputs and somehow missed to use first context - makes perfect sense. Thank you!

Hi everyone, Today I've got a simple setup for vellum: I'm using a wrangle to drive wind with a ramp based of color. I'm able to get the wind to update per frame using the vellum DOP method, but i'm unable to achieve the same effect using the cleaner 'vellum solver' in SOP method. I was hoping someone had a solution to this, getting the same result from DOP to vellum solver in SOP. File: odforce_windperframe.hipnc

Hi everyone, Today I have a bit of a challenge that I think can be solved with some clever vex. One of my favorite modeling nodes for Houdini is 'circle from edges,' because you can pretty much select any curved geometry and get a perfect circle. As you may know from C4D creating circles on curved geometry is quite painful. Here is what the basic node does: Now what if instead we wanted a rectangle with rounded edges: Such as this one which I've modeled many times before, and it always requires taking two circles, expanding edges etc. It would be fantastic if the circle from edges could also support this shape and work just as well on curved geometry such as a sphere. I'm not sure where to start with this one, since I've only been working with vex for some short weeks now. However, any hints/tips or ideas are welcomed. Even a way to expose the code used in circle from edges would give me some ideas. My goal is to use VEX to build a bunch of tools that help model industrial models very quickly in Houdini - usually these sorts of details are very common in industrial modeling. Thank you.

Exactly. I'm currently working on my take to achieve this, will share the file when bug free =)

Oh, nice one. Did you use Fencer's technique?
