  1. Hi! Anyone knows if it is possible to do that in TOPs I mean render multiple frames at once, I try to do that but I get errors. Thanks.
  2. UV cubic map procedurally

    It seems simple but I couldn't figure out how to procedurally create a cubic UV map fora a simple 6 sides cube, Any tips? Thanks.
  3. Rotating uv tile

    This so useful that it should be incorporated in Houdini.
  4. Rotating uv tile

    Yeah I am aware of texture bombing I was hoping that someone knew a simpler way to just rotate the udims independently like Andrew does in Blender. Thanks for the tip thou.
  5. Rotating uv tile

    That is really cool Konstantin thanks for that! Can you tell if there is also a easy way to do that regardless of the surface division like in a single poly plane like this - Rotate uv tile blender tutorial Thanks.
  6. Hi, I am looking for a workflow where I could mix alembic animation for the skeleton and use it to drive a static muscle model, I tried to use the "tissue system" but no success I am also trying to use instead of a FEM a vellum simulation which is way faster so no build in tool to do that as far as I know so I am stuck on how to "stick" my static muscle model to my skeleton animation cache properly, any tips? Thanks!
  7. COPS - Merging nodes not combined ?

    I suggest to use the layer COP in this case.
  8. I am using the Houdini hair tools to groom a character and I hit a wall where I need have my skin groups transferred to my guides where Houdini doesn't do that by default, let me know if I am wrong, if I use a group transfer SOP it takes a lot of time with a large amount of guides, shouldn't the guides inherit the skin groups by default? Is there a efficient way to do it? I hope I am making sense. Thanks in advance.
  9. I am having problems to generate the photon map, when I try to render just the photon map with a simple scene with just 2 objects mantra always crashes. I am sending a simple scene that crashes on my computer so you can tell me what I am doing wrong, thanks. photoGen.hipnc
  10. Thank you so much for your time to explain me that I am totally gona try that, I didn't know that phm() module. I'll let you know what I got. Thanks again!
  11. I have a simple ordered menu that have python script that has a variable 'check', I want that a button on the same node changes the value of this variable, with hscript I just put 'set -p check=1' on the callback script and I can access this variable on my menu's script, how do I do that with python? I hope that makes sense. Thanks.
  12. I think the right question should be how do I access the menu module script from a command button, everywhere I look just explain how to do that If I want to access the module in a digital asset which I think it is not the case.
  13. I have my function on my ordered menu list: import os def listDirs(check): result = [] houDir = os.listdir(hou.getenv('JOB')+'/houdini') if check==1: for dir in houDir: result+=[dir,dir] return result else: result=["Nothing","Nothing"] return result return listDirs(check) I want my button on the same node to pass a value '1' to my 'check' variable in that function, how do I do that? I did try on a callback button: hou.pwd().parm('dirList').listDirs(1) But it didn't work, what am I missing? Thanks.
  14. Is there a way to check if a directory exists with hscript? I try this: set txt='' foreach dir(`run('uls -p /mnt/non_existente/directory')`) if ($dir != "") set txt = 'nothing' else set txt = 'all' end message $txt But if the directory doesn't exist it return me nothing, any tips? Thanks.
  15. Check if directory exists with hscript

    Yes I don't use phyton, but thanks anyway.
  16. Check if directory exists with hscript

    I found a way: # Check if directory exists set check='' foreach dir(`system(" if [ -d 'your_directory_path_or_not' ];then echo 'yes';else echo 'not';fi")`) if (`strmatch($dir,"not")`==1) set check = 'Not Found' else set check = 'Found' endif end message $check But if anyone have a better and more elegant way let me know. Thanks.
  17. Blurring/Filtering Procedural Textures

    Thank you so much for giving your time to explain this to me it really help me understand this, I already knew that do something like this in PBR would involve some more complex calculation with Rays I just did know how to do it, in the old micropolygon days I knew that with some loops you could do it with less complex calculation I guess. My intent was to learn how to average the values like in sops and also to learn how to do it and also I like the idea to do all that I can in shaders but thanks to your explanation now I know the caveats so I can decide better if I should in in textures or not. Thanks again for the explanation.
  18. Blurring/Filtering Procedural Textures

    I just bump up in this older thread which describes exactly what I am trying to achieve with no success off course, I am trying to 'blur' a procedural 'soft dots' pattern more than it's own softness using what i saw on the Masterclass about loops but I it's not working for me, can someone point me on the right direction? Thanks. loop_blur_vop_values.hip
  19. Houdini grooming tools parting lines

    Just confirming that parting lines don't work for me, any more tips?
  20. Can anyone help me to understand how this tool works? I am trying to avoid some guides to interpolate using this but it doesn't seem to work in any way. parting_fail_01.hip
  21. Houdini grooming tools parting lines

    If I do that it uses the parting line guides to create a clump on the floor.
  22. Houdini grooming tools parting lines

    Sorry not for me. I can get a a similar effect by increasing the decay but it breaks the purpose of using the parting lines where some areas I want they interpolating and others where I can define they don't. It seems the the parting lines doesn't do any effect at all even in the old system I never get it to work right and there is nothing in the manual the points to the right direction it only describes what the node does. The only way I can think of that could help me is to make different patches it could work but it is more of a hack and more steps then would be necessary if the parting lines work.
  23. Houdini grooming tools parting lines

    That doesn't seem to make a difference if there is a part line or not.
