  1. 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
  2. Unreal Engine Artists - TRIXTER Berlin

    TRIXTER Berlin is currently looking to hire experienced Unreal Engine Artists. Booking time: ASAP - end of September Location: Trixter Berlin Description: The product we're creating is not a game - we are creating fictional in-game scenes for a live-action film, and we are using Unreal as the Game-Engine. The shots created will not require live-rendering. We are not striving for Photo-Realism – the look of the shots will be comparable to late PS3-generation games, or early PS4-generation games. Responsibilities: Importing rigged and animated characters from Maya into an existing Game world running in Unreal Engine. Staging the characters and placing cameras. Optimizing the shots within the context of a given scene. Tweaking textures/materials and the existing lighting. Minor simulations. Exporting the shots as image sequences. Comfortable in working with deadlines. Ability to work in a collaborative environment. Requirements: Excellent knowledge of Unreal Engine and Maya. Knowledge of CG and Game industry is a major plus. Self-driven, good communicator, and a great-team player. Excellent organizational and communication skills Ability to perform multiple tasks, set priorities and problem solving Able to organise own workflow in a meticulous manner. Good communication, organizational, time management and interpersonal skills. German and English language skills. Valid EU-working permit. If your experience matches above description, we are looking forward to hearing from you! Please send your CV, demo reel and earliest commencement date by email to jobs@trixter.de.

  3. Import Pop Field into SOPS

    Hi all I'm looking to replicate a Houdini sim that I have inside Unreal Engine. I would like to export my vector fields as flow maps that can drive Unreal's native particles so that they still remain interactive (collisions, emission, etc). I'm having trouble accessing some of the native POP fields outside of DOPs. Can anyone explain how to import a POP field such as pop axis force out of DOPs into SOPs so that I can then export it? Thanks! Nick
  4. Im currently using multiple geometry inputs from Unreal into an HDA via the + symbol on the HDA rollout. It works fine for passing the separate assets into the HDA, but I'm trying to separate the geometry so I can randomize which object I use at different parts of the HDA. The documentation states: “When there is more than one geometry set as input, the geometries can be differentiated in the Digital Asset with the Unreal to Houdini attribute unreal_input_mesh_name which is created on the input geometry primitives.” This is great, except that I'm trying to make the HDA procedural in that I dont want to have to manually separate the inputs inside of houdini based on an exact mesh string attribute value because the tool could have infinite amounts of inputs. Ideally the marshalling from Unreal to Houdini would include an index of the asset as a primitive attribute as well but currently it doesnt. I was trying to figure out a way to compare strings in such a way that I dont have to specify exact values as that defeats the purpose of being able to change the inputs in Unreal on the fly, but I cant really come up with clean way to convert the unique string attributes into a usable format. Connectivity SOP would work except that some of the input assets are made of multiple subobjects so that doesnt work in this case. The only attribute differentiating the input assets from Unreal is that prim string attribute 'unreal_input_mesh_name' which is an exact reference of the mesh in the content browser in Unreal. Any ideas on how to split primitives into a group or assign an attribute based solely on a unique string value?
  5. Hello, I am relatively new to houdini - I have used it years prior for some things but now I have just acquired an indie license for development of my unreal game. At the moment I am making a building facade system that will place premade modular pieces depending on a few variables. I was hoping that perhaps some guru's could peruse this little plan i have drawn up for how i envision it to work. at the moment I am trying to workout step 4 by using bounding boxes made from the original geo to select the new resampled walls and place them into sections. I want to bound them and in the groupSOP name the sections per iteration of the foreach node they are inside. finding the correct syntax for this has been a problem so any help would be greatly appreciated. Ill be keeping this thread alive over the course of my findings. Cheers Az BuildingGenerator.hiplc
  6. Hi, I have my heightfield exporting from Houdini into Unreal without any issues, but I can't seem to find any info on how to export the landscape holes. I can set the hole material, but not the actual hole itself. Does anyone know how, or can point me in the right direction? Thanks, Dave
  7. I'm struggling to get data out of the position map, its just grey. I'm assuming its do with the bbox values. In the GDC2017 cloth example there are values here. but when I use the vertex animation node, the -BBOX MAX & MIN values are not automatically filled out. Where do these values come from and how do you get them? Out of curiosity, what are they for and what do they mean to Unreal? Thanks.
  8. 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.
  9. Dynamic RBD - Houdini to Unreal

    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. Pluralsight is proud to offer three new courses... one covering intermediate level ocean shot development, a second covering the development of visual effects for Unreal Engine, and another covering the fundamental math concepts that are pivotal to working within Houdini. Below is a bit about each course and a link where you can check out the course overviews. Houdini: Intermediate Ocean FX by Andreas Giesen Link: www.pluralsight.com/courses/houdini-intermediate-ocean-fx In this course, you'll learn how to setup a procedural ocean and do a flip fluid simulation for a traveling boat in choppy waters. First, you'll discover how to use the ocean spectrum to create an infinite ocean. Next, you'll add the boat, do a flip simulation for a specific area with high detail, and add whitewater and mist. Finally, you'll extend the simulated area and set-up the shaders to render all the layers. When you're finished with this Houdini 16 course, you'll not only have an ocean rendered with a high detail fluid simulation, but you'll also have a workflow on how to master your own ocean and fluid challenges in the future. (Software required: Houdini 16.) Houdini VFX for Games by Andreas Glad Link: www.pluralsight.com/courses/houdini-vfx-games Have you ever sat down in Unreal Engine to create an effect, and not had a clue where to start? In this course, you'll start from the very beginning by creating the textures for your sprites. Next, you'll create debris in a way that allows you to use it repeatedly and uniquely. Finally, you'll add all the extras to really sell the effect, like decals, camera shake, and a shockwave. When you are finished with this course, not only will you have gained a deeper understanding of timing and the importance of telling a story with the effect, but you'll have planted the seed for future endeavors into proceduralism. (Software required: Houdini 15 and up, Photoshop and Unreal Engine 4.) Practical Houdini Math Tips by Beau Garcia Link: www.pluralsight.com/courses/houdini-practical-math-tips In this course, you will learn the math that drives Houdini effects production. First, you'll learn about Sines and Cosines. Next, you will explore the concept of Vectors. Finally, you'll finish the course learning about Matrices, Quaternions, Dot Products, and Cross Products. When you're finished with this Houdini course, you'll have a solid foundation in the math skills needed to produce high end visual effects. (Software required: Houdini 15 and up.) Thanks, and as always, I'd love to hear your feedback on these courses so we can continue to improve! Learn more about SideFX and Pluralsight: www.pluralsight.com/sidefx
  11. RBD to unreal

    Hey all Could anyone point me in the direction to get a rigid body sim into UE4, I've got the Sim (it can be super simple) and I'd prefer FBX. Ideally I don't want deforming geo. The closest I've found is this workflow but it seems like the code isn't maintained. (This isn't mine) LINK https://vimeo.com/124874315 https://www.orbolt.com/asset/LaidlawFX::RBDFBXExport::1.0 I wanted to know if there's something I'm missing. Thanks once again in advance. Brian
  12. Hi ! I was trying to do some Vector Field or Velocity Grid for Unreal. And during my research, many forums redirected me on the asset Velocity Grid Exporter by Benny Yang on Orbolt. That's an amazing tool but it doesn't work on H15.5 with Particle Simulation. I don't know why, I tried to look through the code, but I can't see what's wrong. Do I make a mistake in using it ? Is there another solution to export Vector Field or Velocity Grid to Unreal ? Any help is welcome ! Cheers, Gaël.

  14. I recently came across this student project by Niels van Diermen that I thought was interesting. Has anyone else tried creating terrain for use in a game engine using Houdini and Houdini Engine? http://www.nielsvdiermen.com/?portfolio=procedural-terrain-generation-in-unreal-with-the-houdini-engine
