[FFF: Subject 071, Teaser]

!!!

This is it! I'm so excited to reveal my Houdini Tutorial, with monstrous 38 hours recorded materials.

This tutorial aims to houdini artists who would like to learn new techniques in procedural creation of geometry, volumetric, animation, complex pyro simulation and meet closer with a new Karma XPU render engine.

[RBD - lerp animation and fracture]

How about split tasks, transformations for vellum and then replace vellum "shape 3" with rbd for fracturing, just placing in the same place.

 

[FFF: Subject 071, Teaser]

Thrilled to show a teaser of my future Houdini tutorial.
Key topics:
- Proceduralism: geometry and animation
- Pyro: explosion with love
- Karma XPU: pain and joy

*99.9% done with Karma XPU
Release on gumroad soon.

 

[Train steam using Pyro and point instead of particles?]

Bake source animation into hip file and post here, without this it's hard to tell what is going on or at least do flipbook video to show.

[Pyro trails explosion]

Just wait several days, in H18.5 you will find good presets to start with.

[How to use mask field node in DOP Network in RBD sim?]

Is there a way to blur the mask so that it has a soft falloff?

Sure, just multiply input volume values. Make gradien 0 to 1.

the curtain movement along the railings is from here:

 

I guess the idea is to rebuild a geo on fly, not just stretch or animate position.

Hey Fencer,

Thank you  for taking the time to review this. The solution you have working is quite cool, a bit tricky with multi solver setup - so currently trying to reverse engineer so I fully get it. The idea of using Point deform inside the sopsolver1 and 2 and then merging them.. Nice!

 

I have a follow up question:

Here in this file I've moved your vex curtain to the right, and I've added a simple disc using labs tool (I've also made gravity go up, and pinned the inner edges) -- but you'll notice it doesn't complete the full animation cycle it stops simulating around frame 20ish.

Of course, If I edit the frame on enable solver it will try to do something. Would be curious to see what your solution is, maybe one will come to mind after I've fully grasped your file =)!

Again thank you 

 

Maybe keep faking like this.

[How delete part of smoke, using a geometry (volume)?]

For example, convert sphere to volume and do volume mix operation.

[copy to point with perpendicular direction]

cross product for beginning

@up = {0,1,0};
@N = cross(@up, @N);

 

[using volume vop node to set color attributes on sphere shells]

Several ideas.

[Simulating Cannon with recoil from Pyro]

Looks like you are trying to overcomplicate your task.
Use standard techniques in particles sourcing according to reference and play with pyro look. Add more substeps because of fast motion. That's all.

[Align using meta value]

But the 'Align To' is looking for a name string so wouldn't 'iteration' give me an integer?
I need the Align To to match the name of what is coming into it's 2nd input.
So if the current iterations name is BACK if I type in back in the 'Align To' it all works fine I just need that to read the name attrib somehow.

Thanks

 

Align To - Which primitive to align to. If blank aligns to first primitive in the auxiliary input.

I've read this but still can't see where I'm going wrong.

Hm, if you need to get current loop number you should ask for "iteration" in second block.
detail("../block_begin1_n", "iteration", 0)

[Align using meta value]

Check how it works.

[Create a ramp hill from edges to center]

Try to go from edge to center and control position shift amount based on that.

[procedural tile bathroom]

Try stamp with random rotation.

[Attach Camera to Boat]

Try rivet

[[VEX] Stacking points one above the other using atrrib size]

How about calculate real size of every letter and shift based on it? Looks like you are trying to do the same but I am not sure about your idea.

[smoke has a hairy look]

Again, check shelf tool "billowy smoke".
You are using very low gas dissipate, smoke almost stay forever, at the same time there are no forces to move this smoke except gasdisturb and turbulence which tearing it apart.
Main motion of smoke is Buoyancy (which based on temperature) or wind, in your case temperature disappears very fast, Buoyancy stop working, smoke not rising anymore but gasdisturb keep working.
Find a good reference and examine real behaviour.
