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 a layer to comp for my shot where the floor is lit by a pyro sim that gets REALLY close to it (actually touching). I am using Karma for this project, but understand I MAY have to use Mantra????? Thanks in advance for help =) Nick

I’m using mantra to render some fur texture, but the rendered result seems quite different from the viewport one. Is there anything I can do to make rendered textures look better?

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...

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 (...

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 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 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... -
Hi there! I would like to do a render passes where every object has a constant colour and right now I am doing it via takes ( which is very time consuming to set up). I have also tried the op_id and primid in mantra but that doesn't give me a different colour for each object in the scene....

Hello wizards! I am doing some glass renderings, and for a very specific case I am facing a problem that could be potentially solved by limiting how far a refraction ray should travel. Like, if the next level of ray depth already travelled a certain distance kill it and return the color of th...

shader Where is the Mantra Specular Edge Color ?
Elistan posted a topic in General Houdini Questions
Hi, I can't find a way to get what I can get with a colored specular map in Substance Designer. I'm basically trying to get a fake iridescent effect by coloring my specular map, but in the principled shader, the specular is a float type, so no way to put some colors in there.. In the past I was on...

Hey everyone, Whenever I go to the render viewport in Houdini 17.0.352 I get the following message "Error : failed to save output to file "traceback (most recent call last):" I joined here both the error message I get when I start Houdini and the Message I get when trying to render u...

Hi all! When I create or download assets for outside set dressing (rocks and stuff) I often wished that Houdini had a decent tri-planar mapping shader. I'm used to it from game engines and it is so convenient not having to create UVs for this type of geo! I like to use volumetric modeling...

Hey I am having a problem while rendering my Ocean Surface. Mantra is not displaying anything in the render view. I can see "mantra: Could not obtain vex from op:_auto_/mat/oceansurface " Any Idea what can be the reason of it, It is keep failing the render!!

Hi Everyone, I am trying to create a water splash with separate water trails as shown in the below image. I have created separate sim for splash and main water sim. Using object velocity to emit splashes but unable to get proper shapes of water splash as per reference. Any ideas or su...

Hi all! I'm trying to create a layer material and it works fine so far - using it in a mix works as expected. But when I try to use attributes, e.g. the rest position, the binding fails as soon as I use the material as a layer. When I use it directly (assigned it directly to a geo) th...

This is more of a minor annoyance than anything else, but I'm working through part 3 of that free Rebelway asset creation course and around 9:30 I noticed a different behavior than in the video when trying to shade a VDB fog in the viewport with standard distant lights. It seems like the light gets...

I've been working my way through the free Rebelway asset creation courses and the same tiling method is being used in both of the first two parts for COPs and VOPs tiling. However, I ran into a snag around 4:27:00 of the first masterclass, where Saber bakes out the flattened Torus to assist in tilin...

Is there a way to export just one jpg of the "direct" channel for each UDIM? So far i have managed to export an exr with the final rendered texture, the direct illumination. If i export as jpg the result are really funny colors i guess because both channels are merged? How can i expor...
