  1. Is it possible to animate parameters of a HDA in Unity? eg a noise offset Or... to animate them in Houdini, then have the animation play out in Unity? using $F, or indeed keyframes... eg. a shape that is being deformed by $F-animated-noise, with some grouped faces being blasted (also grouped by animated noise) Or.. is the idea of Houdini Engine in Unity just to make procedural static objects like bridges,roads, modular houses etc? Just trying to do something a little fancier than usual with Unity & the Videolab stuff for the OP-Z synth! I couldn't find much info on animation in the official docs regarding Houdini Engine, or anywhere for that matter!
  2. Yo magicians ! It's my first time using Houdini Engine, and I tested to animated the parameters of my asset, found out that it's impossible to keyframe it. I can change the values, but I can't keyframe the changes. Is there something i'm missing right there? Thanks all !
  3. Hello! I am trying to make use of the Lightmap Resolution_Attribute which can control the size of lightmaps in Houdini. (more info on these attribures... https://www.sidefx.com/docs/unreal/_attributes.html ) No matter what i try, the attribute "unreal_lightmap_resolution" gets not picked up in unreal. At the same time, the attribute "unreal_bake_name" works fine... Someone already asked the same thing a few months ago on the sidefx forums, but no one had a solution. https://www.sidefx.com/forum/topic/69608/?page=1#post-295760 Any ideas welcome! Thx Felix
  4. Hello, I am currently working on an HDA, which allows me to place different objects on points using the "unreal_instance"-Attribute. Meshes and Particle Systems are placed at the right place. The problem starts with BP-Actors, they are placed without the world offset but rather at the 0/0/0 world position. Any ideas on how to fix this issue ? kind regards, Aiden Edit: it looks like it has an offset on the local X axis of around 1000 units.
  5. Hello, I have a particle simulation in Houdini that I exported in a .bgeo sequence and collapsed into a Digital Asset. I import it in Maya using the Houdini Engine plugin, which allows me to load the .bgeo sequence. After shading, my particles are visible both in the viewport and in the Arnold Render View. Everything looks good. But when I try to render them using Render Sequence, they disappear. Same thing for Batch Render. I've tried looking through all the AOVs, using render layers, but my particles just won't render. Is there anything I'm doing wrong? Is the problem coming from the way I export my particles in Houdini, or from Arnold itself? Thanks in advance.
  6. Welcome, in this tutorial you will learn procedural level generation with powerful procedural tools in Houdini for Unreal Engine 4. Obviously the main objective is to give you the techniques you can apply to other procedural level. From start to finish we create a procedural level generation tool in Houdini 17.5 and deploy the finished asset into Unreal Engine 4 using the powerful Houdini Engine! The Tutorial covers a range of intermediate techniques including an in depth look at For-Each Loops, control of the direction of the Normals, VOP and many others. Possibility to speed up your level creation using Procedural Techniques in Houdini Engine. Offers the possibility to automatically generate multiple variations of the level. Helps you find the perfect design. Develop a consistent visual language.

  7. Houdini Engine in 3d max does not work. Non-training version, SideFX Houdini FX 17.5.39. When loading an hda file, the Houdini Engine in 3D max does not respond. Who knows how to fix it?
  8. hi guys I did some render test with houdini and maya redshift renderer. I made particle in houdini then rendered it in maya using houdini engine and redshift proxy file. This image is that I tested to compare houdini redshift render and maya redshift render. A is houdini redshift B is maya redshift with importing particle by houdini Engine C is also maya redshift with importing particle by redshift proxy When I use B, alpha attribute for per particle is different from A and C. Is there any way to correct the alpha attribute? Thanks.
  9. Good day ladies and gentlemen, This student project is a Houdini tool aimed at generating game-ready rooms using predefined asset libraries, developed by myself and Mihnea Stoica, over the course of five months, at Breda University of Applied Sciences. We developed this tool, as part of an outsource group, for a student game project, called Captain Starshot, developed by Double Door Games. We wanted to see how flexible and adaptable the tool was with different asset libraries, therefore, by courtesy of team Morbid, a student game team at Breda University of Applied Sciences, in one week we were able to make a new test case, where the results of the generated rooms looked very promising. All kind of feedback and suggestions are welcome ----------------- Developers: · Gonzalo A.

  10. When there are two outputs, is there any way to use it in Maya?
  11. Hi. I'm working on the tool, that should scatter some multiple objects as intances. I'm using Operator Path as an input source. I am able to pass multiple geometry under it in Unreal(as seen on the screenshots). However I'm getting 1 of 2 cases: 1 - HDA returns correctly instanced geometry(but at each point i have a combined geometry from all inputs) 2 - if I manually delete unneeded geometry in VEX inside copy-to-points loop - I have proper geometry but without instances(each copy is unique) Is it possible to have multiple input geometry scattered across points with proper instancing. I've also added the HDA. The primitive wrangle will manually delete geometry but will break intancing(so I turned it off) scatter_instance.hdalc
  12. Hi There! I am trying to transfer my smoke and water sim from Houdini to Unity but I am very lost. Any ideas?
  13. Hi, I was following the doc https://www.sidefx.com/docs/maya/_maya__mesh.html#Maya_Mesh_MultiplePieces_Output. I can make color set name to works when it is a single entry, but I have a problem with the array. The color set data in Maya was correct, but the name reverted back to Cd, Cd2 instead. Is there anything I missed? I'm using Houdini 16.5.473, 10 Maya 2017, and engine 16.5.473 on win 10.
  14. Hi! I want to make a HDA with a mesh that is formed between 2 editable curves: https://www.dropbox.com/s/ax8bexpm9ba4et2/nodes.jpg?dl=0 It is working fine when I print in 1 of the curves to Editable Nodes in Edit Operator Type Properties. But I need 2 of them to be editable from Unity. Does someone have an idea? Or it is a Houdini Engine limitation?
  15. Hey Forum! Basic question here: When using Houdini Engine with UE4 - Do we need to manually bake out color maps and other uv maps such as those generated from the erosion tools in houdini (flow, debris etc.) ? I have no problem importing the .otl into unreal via Houdini Engine - but it is not clear how Unreal/Houdini share all the data that exists on my points in houdini… Thanks, Sam
  16. I fallowed this tut .. otl is writing.. but maya is not loading it.. It says cant load otl file.. can we fix it?? Thanks
  17. Hi all, After researching for some days, apparently there is no way to export Houdini transform handles into Maya through the digital asset (correct me if i'm wrong). So one way i found to do this would be through the Maya connection editor between a locator and the Houdini asset. So, in Houdini i have a grid and a sphere and the sphere is controlling the grid extrusion by its position and scale attribute. It is a very simple setup with attribute transfer to test in Maya and everything is working fine except one thing. My goal is to control the sphere inside Maya with the traditional "transform handle" so i can control where the extrusion on the grid is happening by moving the handle instead of typing numbers. Once i imported the asset in Maya, i could attach the locator transform handle to the whole asset using the connection editor however, i cannot see the sphere transform node parameter from Houdini in the connection editor, only the main translation parameter that controls the whole asset. After that, the result that i got so far is the locator translation handle transforming the whole asset and not only the sphere inside the asset and therefore, i cannot move the extrusion around. That said, in this case, does anyone know how to connect the sphere transform parameters to the locator handle in Maya through the connection editor so i could control the extrusion on the grid? Any info would be appreciated. Thanks
  18. Hi guys, I've just done this tutorial [ https://www.sidefx.com/tutorials/creating-a-procedural-snowflake/ ] and I wanted to render it on cinema 4d but I couldn't T_T I made it as Houdini digital asset and threw it to c4d, but there was nothing I could see. and when even I send just cube, It worked, but file in that tutorial couldn't be read on c4d houdini engine.... What should I do !?!? Thank you for read.
  19. Python - Houdini Engine

    Anyone scripted anything for Houdini Engine in Maya? Just want to be able to import an HDA. Any pointers appreciated.
  20. Hello there, I'm mucking about with houdini engine in maya and used the bog-standard file hda to get particles in there and it works. So to add some level of control into maya I thought I would add a delete SOP after the file SOP and have this controlled by a slider on the top level of the hda so that within maya you can dial out some particles if needs be. This works as you would expect in houdini but has no effect in Maya. So my question is this. Is this functionality possible or does it fail due to the limitations of nParticles? If it's not the latter then, anyone know what I'm doing wrong? Cheers
  21. Anyone know how to embed a substance into an OTL? I know it can be done and be able to use the parameters of the Substance within an HDA in Unreal, but can't figure out WTF to do and no help in the documentation. 1. I import the substances into a shop net inside the HDA graph 2. Add materials via material nodes in Houdini 3. Add unreal_material with paths to the materials - trying both channels and actual hard paths - ie paths to the substance file itself AND Material'Game/HoudiniEngine/Temp/Material.Material' do not work for me. 4. Add the Substance files to the operator type graph... Nada, just two blank materials imported. Houdini 16.0.600, Unreal 4.15 and the latest Houdini 16.0.620 with Unreal 4.16 both same issues Anyone know how the embedding works? I don't want to set up materials from scratch as I do want my Houdini files to render outside of UE4 as well, so hence, why I want to embed them vs. re doing it in Unreal.
  22. Is the anyone who uses Houdini Engine with 3Ds Max? I tried to use it with Houdini 16.0.557 and 3Ds Max 16 SP3 and SP4, but there was an error message "HoudiniEngineFor3dsMax2016.dlo> failed to initialize." Error code 127 - The specified procedure could not be found ". I reinstalled Houdini few times, checked PATH environment variable - there was no results. After there I installed Houdini 15.0 and Houdini 15.5 - and error disappeared (and in Plug-in Manager appeared HoudiniEngineFor3dsMax2016), but when I tried to create HoudiniEngine Mesh Plugin 3ds Max just crashes. Could you help me please?
  23. Yesterday 80Lvl released a new post: https://80.lv/articles/procedural-technology-in-ghost-recon-wildlands/ It covers some of the design processes that were used and how Houdini assisted in them. The project itself has been a blast to work on! </plug> So I hope you like the article
  24. Frame VR is a rapidly growing, Australian based, virtual reality production company specializing in out-of-home and training virtual reality projects. We are currently seeking a Houdini artist for a quick turn around job rebuilding a polygon reference model of a boat by breaking down it into individual parts and then rebuilding them as Houdini Digital Assets for use in Unity3D via the Houdini Engine plugin. The work can be performed remotely and there is a negotiable budget based on experience. Interested artists should send a link to a showreel of previous work to info@framevr.co
