Hi Guys. I downloaded this FBX file a while back and it's been great. It's a Mark VI ship that's textured. I brought it into Houdini and mantra reads it well. The only problem is I'm using Redshift for the scene with water and I'm not sure how to get redshift to read the shaders or how to connect th... -
I don't do a lot with shaders, so I am not really sure what is possible and what is not, but I am attempting to sample details of one object from a shader applied to another. For instance, I place a curve on top of a grid, then have the shader sample the shortest distance to the curve to drive the...

Dear Forumers, I need to do a snowstorm blowing around a person. I have the idea for the FX down, but if I end up with a bunch of moving, flowing particles how would I render them best in Karma? Thanks Nick

[Solved] How to get interaction between Vellum Hair and Grain
underscoreus posted a topic in Effects
Howdy folks! I've recently started looking into Vellum and I am currently trying to create interaction/collision between Vellum grains and Vellum Hair however it does not seem to come as easy as interaction between grains and cloth. I've used the same setup that worked with my grains and clot...

Hello everyone! I have scene with emissive volume and no density rendered in Karma which is being comped over footage. Issue: since its emissive transparent pixels I was unable to replicate the exact look in AE. Currently ignoring the transparency and using screen blend mode. I have read about...

Hello guys. As title says, I'm created an grayscale procedural texture in Cops network. I'm made it work as displace map, however it comes as huge cost, needing an ultra high detailed grid. I'm would like to use it as bump, since the ideia it's to use that as fine details. I'm couldnt...

Hi, We are working on setting up and rendering camera motion to an environment we created on Unreal Engine 5. Our scene is foliage-heavy, and there is foliage in/as the background. So, from camera view, the foliage isn't visible - only when we go close to it, it becomes visible. To fi...

Helo houdini nation. Just a simple question. I am rendering animation in mantra, and I just want to know if u guys don't know if there is a possibility to set a render time limit per frame. Like Corona renderer has for example, so I can guess the approximate time rendering of whole animation (...

Hello Magicians! I was wondering, is it possible to save the deep EXR from render view? Let's say your render works properly locally, but on farm it crashes all the time. Nobody knows why. So, you render the frames locally and save it in to the sequence folder. Problem is, deep is needed as wel...

Hey all, I'm trying to render out a crowd in mantra, and while my hair and hat styles are working, I'd like to add some variation to the crowd agent itself. I've already baked out maps for each agent via COPs ( 8 each) and the idea is to create a style for each agent, in this case M_01_*. I'm...

Hey Everyone, I'm setting up a pretty basic vellum cloth simulation > a pop wind and a pop force as gravity only operating on one group and that group grows over time. now, when I let it run the solver seems to delete primitives as some kind of tearing effect (ripping apart the cloth unde... -
Hey everyone with the newest Houdini I seem having an issue with the environment light, rendering with mantra. When I insert an HDR or EXR it will be shown in the viewport correctly, but when I hit the render button I get the message prompted seen in the image attached. Help would highly...

Hey there, after years I finally decide to study Houdini more seriously. I'm starting again with the Particles course from Applied Houdini, I just finish my first run with the 2nd vol. and I'm really interested in GPU rendering because of rendering time. It's not that I don't like Mantra (actu... -
Hey everyone, basically what I have is this: and what I want is this: Obviously, it looks like I could just move the pig head up in space haha. But I have a more specific case that requires the pig head to be visible through the plane giving the ILLUSION that it's on top of it....

Hi, I have an issue with Karma and instances. I use Karma as a render node in the SOP context in a ROP node (so not in Solaris). The instances I set are showing in the viewport, working properly in Mantra, but not in Karma. Here is a simple example: This is what I get in Mantra:...

Hi, I am trying to render a volume which has been rasterized from a bunch of points and that volume is in constant motion. The camera pans fast from left to right tracking the moving volume. I have a test camera that's static and if I take a test render through that static camera, the motion bl... -
