Hi, thought I'd share this in this section too: I wrote an article for the german “Digital Production” magazine about my free LYNX VFX toolset. For the article I made a couple of renderings using the LYNX fabric tools. Luckily it even made the cover Here are my personal favorites, the rest...

Hi guys, I've hit a bit of a wall in the new version of POPs. I have a deforming mesh (skinned character), which I have scattered points on. What I'm trying to achieve is a set of particles that are essentially locked onto their source point until a certain time or proximity from some sort of gi... -
Does anyone know if it's possible to use @pscale for vellum grain? I mean to create it on "Grain Source" and pass it to a "Vellum Configure Grain". To a "grain size" probably? Thanks. BK

Hello guys, So ive been trying to test the difference between using a collision object or a collision source in pyro sims. I still cant grasp the difference between each other and when should I use one or the other. What do you think? pyro.mp4

What is the best workflow for adding particles / liquids to a flat tank simulation setup. Think of barrel that is spilled or a hose that is pumping new liquid into a flat tank simulation. I somehow figured out how to add some volume velocity into my tank but can't quite understand how to create...

Hello, i have a vellum source emitting a low res model every 10 frames. How can i exchange the low res output with the high res version? this is my setup, i am working on Houdini 17

Hy there, i dont see my pyro source after rasterizing a very small scale box (0.02). Sim is working but i wanna see my source volume. is it some kind of visualizing problem?
-
Hello! So I have been Having lots of problems to setup the pyro sim on a large scale. Somehow I cant manage to understand the propper settings. I would love a result similar to this: The size of the my sim is 1:10th of the real size because as I make the sim bigger...

Hi guys, I have a question concerning the new fluid source in H17. How can i create a pump source from curve (point) to drive a FLIP simulation (technique used to create a boat's wake effect) with the new fluid source pipeline. I'am really confused about the new pipeline, and don't really und...

What makes a compatible compiled SOP, there is something diferent from the usual cookMySop function in C++. Or someone have a example from some compatible compiled SOP node? Thanks Wanderson

How is it possible to source in RBD objects (hero) into DOP over time?
-
Hi guys, I'm in trouble with the new Volume Source node. I can't import a simple VDB from SOP to DOP as a collision object, let me explain better. There is a Pig Head converted in VDB by Distance, it has got two attributes: surface and v. After creating a simple DOP Network, I've tried...

Hello, I am doing a big ocean simulation where a wave is hitting a object. And there I want to create whitewater(spray) splash. But I don't want to create foam and particles to spread in the whole tank instead of that I want the particles to spread in a particular defined area, So that sim...

hi, I have a question about this display function: white water source > visualization > show surface Then blue object shows up. I know this object represent VDB, but I wonder how this tool creates the visualization. I dig into >edit parameter interface, but cannot find any particular tric...

Hi everyone, For an upcoming project, I need to create the effect of an extension cable overheating. ie. holes being burnt in the plastic casing of a wire and then smoke emitting from them. This is a good reference, particularly the shot at 1:26 https://www.youtube.com/watch?v=jGPkkOU...

Advanced sourcing for Houdini. it’s not only 10-100x faster but also gives more control over sourcing especially when many sources involved in sim. Houdini16 Hipfile with examples included https://github.com/abryutinalexey/vdb_to_field

Hey! Question about fast moving pyro sources. I included a scene which is similar to my actual scene. I have an object from which I want fire to emit. However, when the object starts to move quickly, the flames practically die until the source comes to a stop again. This seems realistic, like i...

Hi, How do I properly source a volume I already created, and use that for pyro? I made a cloud using the cloud node, and added some noise. I am trying to use it as a source for my pyro sim to have dynamic clouds. For some reason, at frame 1 there is no density. Then the volume fills up. Shouldn...

Hi everyone, Here's a weird one: I am trying to use the crowdsource to copy a simple agent animation on a point sim. It is basically a swarm test. Now the problem is that when I try to render my agents they render as boxes. So far I have done a couple days of research but I didn't seem to be...

Hey,I have a pyro sim, and for some reason, I am still seeing heat in the shape of the source. I turned off the source fuel and temperature, so why am I seeing this? BTW, it only shows in the viewport. When I render, I don't see it.Thanks

Hey Guys , i have a fast moving flip source , and cant get smooth shape , it look like emitter shape while emitting , i tried many different solutions like , putting time blend sop,trail sop , increasing substeps but always get same result . i had this problem in realflow too , but i fixed tha...

Hello guys! I am having a problem with the parameters on the Fluid Source SOP. I am reading the documentation and it says that I should have a "Source Amount" parameter on the node, but I cannot seem to find it. I tried accessing the Parameter Interface but I cannot find it in there... I just need t...

Hi all. I've been learning much about smoke sims in the last few weeks. I have here a smoke test and I'd like to improve it. There's a number of issues going on here, but the first one I'd like to get to the bottom of is the way the smoke is popping (pops) into existence. In the clip below, th...

Hey guys, Just having a bit of an issue that is puzzling me. I have noticed that when you emit particle fluids from an object, it only emits from the object surface. I have attached an example image demonstrating the problem I'm having. I have set up custom velocities which will need to be applied...
