  1. Mid-Snr Houdini Generalist

    DupeVFX are looking for a Mid-Senior Houdini artists to join our small growing 3d team in East London. We are currently at the stage of switching to an almost full Houdini pipeline, wanting to take advantage of using Solaris and USD to drive the pipeline backbone and PDG for automation. The two roles we are currently interested in are: - Lighting artist with production experience using Arnold for Houdini. Solaris experience a bonus. - Pipeline oriented Houdini artist to help develop our Houdini/USD/PDG pipeline and integrate with our internal pipeline tools. We would also welcome very experienced supervisors that have run multiple shows using Houdini as the core DCC. To apply send an email to joinus@dupevfx.com
  2. Solaris Physics

    Hi guys, does anyone know how to set up the solaris physics simulation for layout to be able put geometry inside another geometry? I tried to compute again the simulation proxy but it doesn't work. They show in the Solaris that it's possible so I am confused how to do it. Here is a gif image to better describe the situation.
  3. Wondering if there's a simple way to capture a buffer of the current rendered state of the Solaris Stage viewport. Given that the Hydra render delegate is specifically designed to be able to easily "bolt on" different renderers, I imagine it's exposed somewhere, but given that I'm new to both USD and the Houdini HDK I was hoping that someone would be able to point me in the right direction. In Maya I'd call, target = targetManager->acquireRenderTargetFromScreen(MString("viewport")); Is there an equivalent in Houdini, and more specifically the Solaris render viewport? Thanks.
  4. Hi, So I'm getting started with arnold through lops. The solaris workshop from sidefx is great but since we use arnold I'm missing a few pieces of the puzzle. 1. Aovs, is it correct that I need to create one rendervar node per AOV I want to export? I have tried both Raw type with "RGBA", "N" etc and LPEs: "C<RD>A" but don't get any output. 2. Is it correct that after the rendervars are defined we add a renderproduct node to reference all the rendervars, and give the image a name, is this where we add frame padding and fileformat, .exr? 3. Rendering with arnold standalone. After the "renderproduct" we add "rendersettings" and "usdrender_rop", none of those has any settings for exporting .ass files, do we render the final shot-usd file directly? And in that case what do we submit to deadline for example, a husk-job? If so what sort of licenses are used to pick up husk jobs? Any clarifications are greatly appreciated. Regards,
  5. Hi all, I'm not a lighting or shading person. I'm barely a Houdini person, if the truth was told, but I struggle on... I am having a terrible time trying to figure out how to assign random textures to packed geometry in Solaris/Lops/USD/Karma (referred to as SULK from now on, OK?) I have a Crowd scene with some flag waving agents. I want the flags to have a material on them where I can choose a random texture from a set of three textures. With me so far? Excellent. How? I've tried 'editMaterial' node I've tried 'materialVariation' node I've even looked at 'variations' but that's s total mess in there - I'm not going anywhere near that! The flag geometry is packed and has an attribute called 'flagTex' which has a random int value from 1 - 3. When I import the geometry into SULK, that attribute becomes primvar@flagTex So far so mediocre. Now the problem: How do I use that attribute to choose a texture file on the shader? I can do this in Mantra, so I would expect it can be done in SULK, but how? I expected SULK to relieve some of the pain of StyleSheets but in truth it is a lot worse. Please, someone, help me out here before I throw in the towel and ditch SULK. Many thanks. Dan
  6. I am trying to get velocity motion blur and geometry motion blur in Solaris RednerMan 23.2 and Houdini 18.0.391, both of this motion blur working fine with karma I can't get this work in RednerMan in Solaris . All of this motion blur works outside Solaris , only inside Solaris RednerMan doesn't show any motion blur, I tried batch render it doesn't help. only geometry motion blur shows with large shutter in camera but I can't find any way to add more geometry samples in RednerMan . There is no information about motion blur setup on RednerMan Solaris help file.
  7. Shading Theory with Karma

    I'm happy to announce that I've teamed up with SideFX to release a new free course! - Shading Theory with Karma. These videos are designed to teach you the fundamental ideas behind shading/texturing while utilizing the principled shader, karma, and my dear friend - Shaderbot. Visit CG Forge to download shaderbot along with access to the videos for free. https://www.cgforge.com/course?courseid=shadingtheory Have a nice day,
  8. Hi I have gone through docs, forums etc and cannot get any kind of motion blur working in Karma. I have added the cache node. I have increased the distance between shutter open and closed to maximise the effect of motion blur. Nothing works. I just want to see motion blur when I change my viewport from Houdini GL to Karma.My other question is the docs say in order to save out you usd geo to motion blur in the future you need to change the data. What data where? I have Multiverse USD install in Maya and for an idiot like me it is super straight forward to see how to export sub-frames for motion blur. How do you do this in Houdini?Screenshot of multiverse usd write from Maya In the example hip file I have taken out my ABC file of a ball rotation ans used something internal instead. No luck all all. https://paper.dropbox.com/doc/Write-USD-Asset-87RXiZG8ex6z7EAh6unM0 windows 10 H 18.0.391 All the best Mark introTo_usd.hipnc
  9. Hey hey there, I came across an issue and hope to find some help here once again I tried searching but didn't really know what to search for and then ended up unsuccessful. I am trying to create a Solaris/USD network with my python script but when I set the list parameters on the instancer node it only changes the choice visually but does not actually use it. As an example, when I set the "Prototype Index" to "Name Attribute" manually, the UI shows a new field to enter the name attribute. When I do this in Python: usd_instancer.parm('protoindexsrc').set("Name Attribute") usd_instancer.parm('nameattr').set("instancename") the "Prototype Index" gets set to "Name Attribute" but the extra field is not shown and the node behaves as if it's set to its default value. If I then open the list and click on "Name Attribute" myself again, it shows the new line with my correct name attribute. How would one go about solving this? Is there an extra function connected to this list choice that I have to trigger as well in Python? As always, I am very grateful for any pointers, ideas and help! Update: I noticed now that sometimes the script does not even set the list parameter. E.g. when I open a fresh scene, use my script, it creates the instancer with default values (no errors though). When I run my script again, it creates a new instancer with the list set to my values, but still having the initial issue mentioned above :/ Update2: I also posted over on the sidefx forums now and have a small screenshot to show what I mean:) I set the parameter in Python, it evaluates correctly in the shell but is neither shown in the interface nor actually used. Take care, Dziga
  10. Hey, I was wondering if I was the only one having this issue with Karma on H18 : I can't use geoLight or emissive Volume to light an other object. Any idea ? Maybe it's still impossible on the early beta version.. Sylbert. PS : I haven't find a way to setup the amount of ray limit in Karma setting as well..
  11. Hi all I've been looking at creating usd variants from the following, thinking on using this to create a model with variants from a piece of geometry that has a primitive attribute called "myattr" with 2 values (say half a sphere with myattr="left", and the other side called "right") 1- sopimport an object into LOPS with prim attributes. 2- create an add variant to existing primitive block 3- done Any ideas on how to iterate through each of the primitive attribute values to create this variants? adding a hip file for reference, maybe someone can help Thanks in advance! usdvariants_from_groups.hipnc
