  1. Hi there, I'm having lot of headaches! I made an extended ocean flip simulation and, once I convert the particles into a mesh, I would like to bake the surface geometry displacement as texture. I tried to transfer velocities to Cd through VOP and use COPs for bake out the color map, but I wasn't able to do it. Basically I'd like to achieve the same result of Ocean Evaluate node in which I can export texture and choose the Cusp to be in alpha. Do you think is it possible to do that?
  2. What's the simplest and most bullet-proof way to display a texture on a simple grid in Houdini viewport (i.e. real time openGL)? I've tried using simple materials (like "Constant" or "Principled") but it seems clunky. I always run into issues like requiring several settings in "Display properties" for the texture to show up, or the textures (read from files) not updating in the viewport, if I change the texture path etc. Ideally, the texture path would be just a string attribute on a grid, and the viewport would show it right away, and react to all path changes instantly.
  3. SHOP - how to get wire boolean?

    Hi. Is any variable that stores information about wire existence in shader editor? I mean, I need the variable that is 1 when the texture is connected to base_color slot and 0 when there is not. What I'm trying to achieve is the arnold texture preview in the viewport. I created a texture tag in the parameter interface and it works but I want to the “use Texture” toggle be connected with the variable I mentioned. Also, is it possible to get the name of the node that is connected to the slot? In my case, the result would be “image1”. If not, is any different way? Thanks.
  4. Howdy, I'm running into memory issues when baking textures (using the Bake Texture mantra node). Right now I'm unable to bake 2048x2048 textures on a machine with 32GB of RAM at a 16x16 sample rate, which doesn't seem right. I'm seeing two different bad behaviors: 1. It starts rendering and the RAM usage just builds up and up until eventually it crashes. 2. It renders until the RAM usage is basically maxed out, then the CPU usage goes down to 3%, and the render never finishes. I'm not sure why it's not flushing any of the RAM as the render goes on? More details: I'm not rendering any extra image planes. I've tried png, exr and rat file outputs. I've tried setting a Cache Limit using both memory ratio & fixed size, but neither seemed to do anything. Running on Windows 10. Houdini 16.0.557 Looking for ideas for how I can fix this. Hoping there's something stupid I forgot.
  5. Hi All, I'm looking for some help. I'm digging into shading VOPs and want to set some conditional switches. Unfortunately, I could not find relevant references for this particular case. I want to check if the Texture node (Opacity) has a valid link and switch to a constraint if not. Two-way switch is set to RGB color. It does not work the way I thought it should. What do I miss here? Maybe is there another, more obvious way to achieve it? Thanks a lot!
  6. Hello; Please take a look at image bellow. I have some questions about texture browsing in Houdini: 1) In texture path, how can I reset image history? 2) Is there any option to browse COPs oprators (like CTRL + Click on file browser)? Thanks.
  7. i have this geo and i want to apply random textures from a folder hierarchy. i friend of mine helped with some python code, so now i can select a folder randomly and then get the first image of the sequence with a little tweaking i managed to plug it in a quickshade and converting the file numbers to $F4 or $F3. so it should read the sequence BUT!! although i have the iterations attribute of the foreach meta node as a seed for the python script, the same image applies to all primitives. What is missing? Side question: why are the uvs rotating? any tip much appreciated, houdini forums are bit dry right now random_sequences.hip untitled.bgeo
  8. Hey there, first poster speaking So i have a id map of a landscape (an example is in the attachments) and i wanna get terrain masks defined by each color (green for grass, blue for water and so on). so i somehow need to transfer the textures's Cds to the heightfield to sample them, but i cant figure out how... :S in the end i would like to just define a color and the wrangle spits out a mask. sounds really basic but i have no experience using volumes. did research way too long for this, for something which surley could be done in minutes :S would really appreciate any help!

  10. Hello folks, After enjoying myself immensely shading in Mantra (Kursk and Angel Has Fallen) for two years, I now find myself in a new Houdini situation: Arnold. Why Arnold? It is one of those situations where multiple vendors are handling the same assets, so my hands are tied here. Anyway, I have no end of trouble getting Arnold to render my textures. Primitives or existing geometry assets can be shaded and lit, but once textures are added to the mix... nothing (that is they render black as that is the missing textures colour). I must be missing something painfully obvious. My best guess is that Arnold somehow doesn't automatically pick up the UVs of the primitives or other imported geometry, because if I add a UV texture node to my box primitive, I can get textures on it. But the primitives' native UV layout is lost (or never activated). So... who can be the man of the hour and point me in the right direction?
  11. HDA x C4D & Materials

    Hello ! Just have a noob question here. I'm starting to play with hda in Cinema4D and can't figure to achieve something. After doing some researches I can't find a way. This is pretty simple, if I made a hda in houdini who contains different colors for point or primitives groups, how can I apply different materials in these groups in Cinema ? Exemple : I've two box merged into an hda and I want to apply a material to each one in Cinema 4D, is it possible ? thanks for your help !
  12. Good evening! Can I ask U guys for advice? Im trying to create ramp between three textures (but with same uv map), defined by paint SOP on pighead testing geo. And what I want to ask U is: Does it possible to somehow assign different textures for each color, in redshift? Any advice will be very, very helpful to me! Thank u guys so much! textures_issue.hip0.hip
  13. Baked N texture is "tiled"

    Hi there! I have quite stupid problem with attributes baking to texture... I need to bake high poly on low rez: I am using the "old school" way by using bake texure operator, not game tools (because the pipeline must be stable without any beta tools involved. Result is good enough except edges sharp edges on Normal map: I wouldn't make a flat source as Rohan advised here: http://www.rohandalvi.net/baking Can you advise me please how to avoid that "tiling"? This is my scene: ProceduralBaking.hip Thank you in advance!
  14. Hello, I'm trying to assign identifying colors through textures. My models will have UVs with the appropriate textures made for them. I'm doing tests now and am having trouble transferring the texture to the geometry. I'm using the attribute from map SOP and my UVs look correctly laid out but the result is not right. However when I apply the texture with a principled shader it works correctly. Does anyone have any advice on how to fix this. Images of problem Thank you!
  15. Hello, Here is short video showing how volumes can be used to shade and texture semi-translucent organic things. Volumes For Organic Assets This approach allows to achieve close-up realistic organic look for semi-transclucent assets where SSS or colored refraction is not enough. An object with UV's is converted to signed distance volume with UVW grid. Then volume is used to set density and perform uv lookup in rendering. This way density can be adjusted by depth. I.e. not so dense near the surface and very dense at the core. Or not very dense, then dense patch like island of fat, then not dense again. UVW grid is used to texture volume. Different textures can be used at different depth. This approach allows very flexible yet powerful way to place any texture at given depth. Texture X at depth Y. I.e. big veins are 5mm under the surface. This approach is best for close up organic hero renders where SSS or refraction are not looking good enough.

  16. Hello guys & girls, I was wondering if there is a way to have Objects being fractured by a given texture like the Trace SOP does it, but on a existing object? Thanks in advance! Something like this:
  17. I am trying to bake textures into a new uv layout. I created uv2 attribute on vertices, but don't know how to tell baker to use it. An example of this in blender: https://www.youtube.com/watch?v=h880hxH-BC8
  18. Hello everyone! Please tell me who engaged in the creation of lava in the Houdini. I need to create a procedural texture of magma so that it follows the surface of the geometry. Also, perhaps you know how to create dark folds on the surface of the lava as it cools. Thank everybody in advance! The dark folds
  19. Hi everyone. I am trying to "copy" images onto my imported point positions in cops. In the example file, you will see that I have successfully imported my point position into cops, but I am not sure how I can go about placing an image (the center of that image) on a point coordinate? obviously I would want to control the size of that image once placed but I can cross that bridge when I get there. Thanks in advance. texture_placement_odforce.hip
  20. Is there a way I can get the colour from the Heightfield Quickshade into a cop2net. I've tried sop import but it only cares about the heightfield planes (height, sediment, debris...), but I need the colour. The real objective is to get that quickshade result out of Houdini. I couldn't do it with a heightfield output, so I thought I should try via the cop2net. But first how to get it into the cop2net?
  21. Attract/Morph particles to texture

    I have quite a simple question but haven't been able to figure it out yet. Using attribfrommap I have particles getting generated from a texture (e.g. circle). How can I attract/morph these particles to another texture (e.g. rectangle)? Thanks
  22. I'd like to use tx as source texture format, not ask any renderer to convert sourec pngs or exrs, but start from the beginning with tx format. Is there a safe and reliable converter to tx? I've already searched, but I'd like to get your view / which one you use / which one you recommend.
