  1. Heya folks, I've been trying to test out a setup where a volume inherits color from geometry which in turn is used to color smoke simulations. I have a attached a file with my setup - where I'm initializing a tempCd field and then transfering that to a Cd field with gas calculate and then advecting Cd with vel. However, the issue with the sim is the fact that it refuses to initialize multiple colors. I hope somebody can help me figure out how to troubleshoot this issue. Thank you! smoke_color_sim_test.hipnc
  2. With the recent 16.0.6 update, Houdini added games shelf tools. one of these tools is vertex animation. I've been trying to integrate my particle system into Unreal Engine 4 for the past 2 days. When I try to render the vertex animation subnetwork gives this error: Error Error rendering child: /out/vertex_animation_textures/mantra11 Diving into the subnetwork there's two nodes that give errors the first node gives this error: Error Zero resolution for camera '/out/vertex_animation_textures/sprite_obj/cam1' and the second node gives this error: Error Error rendering input: /out/vertex_animation_textures/mantra11 From what I've read from another odforce forum post the problem seems to be that the HDA for vertex animations textures need to be used correctly. Quote from Gramx's post: " Hi Luiz, I have been looking at the hip files and it seems that you have a newer version of the Vertex Animation Textures Asset. I get an error saying incomplete asset definition. Are you able to send over the latest asset or will it be available in the next Daily Houdini build. I am running 16.0.542 Thanks Graham " Gramx's post Shouldn't the tool just work on it's own? Or am I doing something wrong? Any help into the right direction would really be appreciated, maybe even an example of the particle working in Unreal. Cheers, Callan RubberParticles.hipnc
  3. Has anyone tried masking fields in Houdini while using Finite Elements? I am trying to mask the Gravity field in a Finite Element simulation in Houdini. But I cannot get it to work.

  5. Hi Guys! So the other day I watched this video and trying to apply this method to my current project. I understand the basic principle behind this method, but when I try to do this on my own, I found several difficulties. =========================================================================== 1. First thing is that how to pipe P attribute into vopcop 2 generator, I might have figured out, which is by dive into vopcop2 gen node -> tab -> Import Point Attribute -> select pre cached file 2. If we successfully import the P attribute, how to assign the color value( converted from P) on to the right pixel, Ex: point number 0 [X Y Z] convert to pixel number 0 [R G B] yup these are probably all I found and tried for now, I really really need to figure this stuff out. Looking forward to you guys' suggestions!!! Particle SIM2.hip

  7. Hello everyone, Are you curious who our new GridMarkets Featured Houdini Artist is? Meet Saber Jlassi, Senior Cinematic TD at Blizzard and also a great Houdini teacher! Hope you enjoy the feature, Patricia and the GridMarkets Team
  8. Would anyone know how to pre-fracture geometry in houdini, bring it into unreal engine and have it be dynamic (responsive to real-time collisions)? I know unreal has a way to do it and be dynamic, but Im wanting to be able to art direct from houdini for the area where my collision will happen in the level. I have already tried pre-fracturing with voronoi and exporting as alembic and fbx but no dice. Just wanted to see if anyone had a solution to this. Any ideas?

  10. I've been practicing particles using Rohan Dalvi's Tutorial:Rohan Dalvi's tutorial Everything has been working great so far except for one major thing. If i compare my renders to Rohan's, my particles seem to clump together and generally have a larger scale. The left picture show's my particle render and the right shows Rohan's One issue i've considered to be the cause of this is that Rohan is using VOPSOP from 13 I'm using 16 and point wrangles, so maybe something is going on with the scale in there. I still only have a couple months of experience so any help would be great. Cheers ParticleDisintegration.hipnc

  12. I've always been fascinated by procedural set modeling, so I figured I'd try my hand at modeling some tropical marine life in Houdini. I'll be posting my progress here! I have started hashing out a few basic types of coral, anemone, etc. Hoping to eventually get this all into a large scene. Anemone motion test: I apologize, but I cannot currently share hip files of these scenes since they may be used in a contract.
  13. Hello, I'm trying to get particles to drive a pyro simulation to create a flamethorwer effect. However i keep getting random unexpected motion, I've tried sourcing the velocity of the particles to fix it but it doesn't give the look i want. I've attached my hip file Dragon_flames5.hipnc

    Hello! I'm animating a burning match, and here is my problem : The ignition starts too slowly, even if I set up a fast fire. Is there a way too fix this? This is the kind of ignition I would like to make : Thank you!
  16. Hello everyone, This is a simple introduction to using Vex.
  17. We need a Volumetric Smoke Explosion similar to the first one in this video… It is to be placed into a simple motion graphic piece (replacing the Shutterstock footage)… https://vimeo.com/216282325 password - smoke We need it early Sunday 7 May (Sydney, Australia time). Very soon. A more detailed brief is below. Please email if you are available. Thanks. info@jasonmarshall.com.au +61 407 045 482 (Australia) Brief… As you can see in the WIP video, there are 2 base colours.. orange & purple. Please supply… 1 x Volumetric Smoke explosion that can be easily re-coloured in After Effects OR 2 x Volumetric Smoke explosions… 1 x Purple and 1 x Orange (see RGB values below) Orange (RGB values) R- 219 G - 129 B - 46 (Hex Value - #db812e) Purple (RGB Values) R - 115 G - 82 B - 157 (Hex Value - #73529d) The Volumetric Smoke explosion must start in the centre of the screen coming directly towards the camera. Smoke must look great on a white background. Must be supplied with a transparent alpha channel. Must be rendered at a high frame rate (50fps or higher) / slow motion so we can speed ramp it in After Effects. Duration (at normal speed) 7 seconds. (longer in slow motion) Dimensions up to 4K would be great but minimum dimensions are 1920 x 1080. Delivery time - WITHIN THE NEXT 24 HOURS We need it delivered early Sunday 7 May (Sydney, Australia time).

  19. Hello mates i have a question... is that only me or does anybody has same promblem too? so , I am trying to export my scene/models to Unity with FBX export but my texture are not coming and i dont wanna deal with giving matariel in Unity for each model. I am using Houdini 16.0.504.20 and installed Unity Engine also and using Unity 5.6 and I created digital asset in Houdini on .hda format and aslo tried .otl too and they dont show up on Unity. So, i know these are two different questions but primary problem is exporting my models with textures with FBX , does Houdini support that like max? or nah?
  20. Like a sphere or a motorcycle in 120km/h around . i don't want big fire, so in source volume node i turn source volume option to copy, then i get clean fuel field , but pyro can't emite the fire properly as static object. This picture is source volume in add type. So anyone has same problem?and know how to solve this one ? Please.
  21. I'm trying to add this geometry to the primitives of an object, in this instance a cube. I'm quite lost and have no idea how to continue, any suggestions? Also, is there a way to have a rectangle spawn from the corners of the grid towards the center, whilst following the height of the surface? VFX1.hipnc
  22. I am having a couple issues. One i am unable to get mantra to render a single frame. It tells me i have to delete all of my nodes to render. my second issue is that my shattering glass that i cached out is not showing up when i source it into the file node. Also when i link all 6 furniture files, the debris, bricks and pyro explosions that are pre-cached, Houdini crashes. Please have a look at the scene files and advise.

  23. Hi guys! I would like to share with you one project made by our student who has accomplished our Multi-Dynamics course: https://vimeo.com/209750174 Two groups have just finished this program. Now we invite everyone who is interested in improving Houdini skills to join us. The next course starts on May 20th, 2017. The program of the Multi-Dynamics course is focused on solving non-trivial dynamic tasks. We master the knowledge by creating FX-assets using virtually the entire selection of Houdini solvers. You can find more details by following the link http://onlinevfx.ru/eng/courses/9-course-houdini-multy-dynamics
  24. Hello, I have done another disintegration effect on a sphere, that I need for the end of my animation for university. I have alembic cached out a girl from Maya. It only has subtle animation on it. The girl geometry needs to be swapped with the sphere so the effect is applied. I have attached a file with the cache's in it but without my attempt at swapping the geometry as it crashes Houdini. The animation starts at frame 2670 Thank you! disintergration_ballet_007.hipnc END_Death_camera.fbx End_death.abc
  25. Hi people! I'm learning some things in Houdini to create HDA's for cinema 4d or export vdb's simulations to render in c4d. In this case, I want to make a smoke simulation but I have one basic issue that I'm sure it solves with a simple way. I have one torus emitter inside of a tube but the smoke doesn't respect the tube geometry, It moves through it. How can I fix it? Thanks!!
