Also... If I change the COPs resolution to something else, I get an error. I feel like any change made to COP container breaks render...

What is the latest setup for triplanar projection? I tried with COPs Bake Geometry Textures (first screen) and in the Material X subnet (without cops, second screen), both look... off. @tamagochy How to make blending ramps less aggressive? How to fix the normal map to avoid artifacts?

@fencer Thank you! The "aov:" was the trick

dot seems ok

@Librarian That is a very complex setup I was not able to figure out what I should adjust in mine... @fencer Tried mtlxdot instead of karma_aov, did not work...

Try with mtlxdot

How to create custom AOVs in Karma? I followed the documentation, but it does not work. Am I missing something? Here is the scene: karma_aov.zip Created new Extra Render Var, named XXX, trying to output diffuse_color from subnet1 material.

Your triplanar blending ramps to agressive. Also you can check kma_hextiled_triplanar to recreate it logic in cops And this artifacts coming from normal map you created

I have a noise texture and triplanar projection. That setup gives a lot of artifacts. How can I get rid of them? cop_snippets_006.hipnc

Hey magicians, Any clue on how to achieve something like this? been wrapping my head for 2 days trying different stuff, I was able to get some "alien like" creatures, but this feels more elegant overall and "light". Not sure if is better to start with vellum, or using some curl noise to get some nice flowy curve splines, but even so, is hard to get the "cloth" part from there after. Any thoughts would be helpful Thanks!

Ok, I noticed that the error happens if you set up material X with COP textures and then rename COP network. Unable to fetch texture file from COPs: op:/stage/DIRT_MATERIAL_maps/VARIATION_MASK[1] This DIRT_MATERIAL_maps was renamed and start throwing errors. Any way to fix that?

According to sidefx documentation single pass reseeding "requires careful setup of the input fields". What is different compared to the standard set up? are there any additional requirements for set up? I assume we are here only talking about the "surface" field, or is there a another field?

Hello, I have a super basic scene with a COP texture (triplanar projection), and I am getting errors I can't understand. First, I get an error on the NULL node (VARIATION_MASK), which is set up as triplanar. Maybe something is wrong with that setup, but then I have errors on the usdrender_rop1 node. Tried without triplanar, and I can't even render VARIATION_MASK_FLAT, which is just a fractal nose. I get issues displaying textures in the viewport; sometimes it works, sometimes not; changing the path to texture "op:/something" >> "op:something" helps or breaks. I jsut stared to dig into COPs and am confused about what's going on. Maybe someone can take a look at my scene cop_snippets_001.hipnc and find an issue?

Hi Guys, I just want to share un Wheel generator (redshift). https://hipfreak.gumroad.com/l/hnjfsa Thank you.

Wrap new nodes into one subnetwork and use the logic as before. Alembic, USD... Save script as a shelf tool. Improve script to be able to select "subnet_path", fully create "attribdelete" instead of copy-paste. Google Python examples, you will find close enough to this tasks.

Does anyone know how to change node handle size of camera manipulator in Houdini? The standard * & / does not affect camera manipulation handle size. preproduce issue: in SOP or in LOP When select camera and press enter, multi handle appears and its uncorrelated to translate or rotate standard size that is controlled with * and /. Houdini 20.5 Thank you for your time!

Ok. Right. I ran the script again and found it was that indeed. My bad. Also...while importing the fbx, I came across a better import option that places materials inside the existing matnet instead of creating a new one inside OBJ network. It also creates all parts directly at the OBJ level, rather than nesting everything inside a subnet (which is what my earlier method was doing). Would it be possible for you to tweak your Python script to work with this setup instead? Here's the updated project file. https://www.dropbox.com/scl/fi/e9np7kw2n0n90s5myjrmn/wristwatch_updatedone-Copy.hiplc?rlkey=slt4wfz55snmtf2ljitfi4wzc&st=dtmr0k66&dl=0 Also, I had a broader question.. Is there a no-code way to achieve something like this in Houdini? Right now, this approach requires knowing Python, remembering the logic, and executing it each time. Is saving these scripts in a file the standard workflow, or is there a more efficient way (like shelf tools, digital assets, or something else) that you’d recommend?

I am trying to create a "USD MaterialX Builder" subnet in my Material Library LOP and failing. The only working solution is: builder = matlib.createNode("subnet", "material name", run_init_scripts=False) But it creates a regular Sunbnetwork, instead of a Material X Sunbnetwork. How to get proper subnet (shown is a screenshot, I created it manually)?

Thank you Konstantin! big fan of your videos!

attribdelete is set as render node already not sure I understand what this issue is, jump to operator shows exact material applied to the node

Another thing. Is there a direct way to select materials of each piece rather than checking what material is applied to it in the render tab by selecting the obj node and then going to the matnet and then searching for the name amongst 50 materials used in the project, and then clicking the material node? If I click on this button on the right side of material it opens a window containing list of all materials inside the model. Doesn't open the directly the material network of the material applied to the geometry piece. Jump to operator button right next to it only shows this panel.

Thank you!! Wow! This worked quite well! Is it also possible to set the display flag to attribdelete inside each of the parts in bulk too?

1. Create an attribdelete with required parameters 2. Windows > Python Source Editor selected_nodes = hou.selectedNodes() source_node = selected_nodes[0] subnet_path = "/obj/Hublot_King_Power_F1___Watch_fbx" subnet = hou.node(subnet_path) file_nodes = [n for n in subnet.allSubChildren() if n.type().name() == "file"] for file_node in file_nodes: parent = file_node.parent() copied_node = source_node.copyTo(parent) outputs = file_node.outputs() copied_node.setInput(0, file_node) 3. Select attribdelete to copy to 4. Appy script It will copy-paste selected node into each node in Hublot_King_Power_F1___Watch_fbx subnetwork and attach it to file* node
