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!

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.

No one?

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.

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.

Yes I don't use phyton, but thanks anyway.

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.

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.

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.

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

Just confirming that parting lines don't work for me, any more tips?

If I do that it uses the parting line guides to create a clump on the floor.

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.

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

Anyone?
