Hi everyone, Just wanted to ask a question. We run in to this problem a few times a year where a client asks us to visit an old scene. When we have updated redshift. I try to not usually update redshift to something in a point release that will break backward compatibility. usually change on a big release. but unfortunately, I have done this time around. Does anyone know of any scripts that someone might have released that would go through the scene a rebuild - lights materials and cameras, keep all keyframes, expressions, parents etc so its the same scene just built with updated nodes for redshift? if not il just have to look into writing something myself, but just wondered if anyone had come across a script that might work for us. cheers

I would defo be up for seeing the code. and I am sure some other people would be too. Scene Callbacks - what do you mean by this? can you elaborate? didn't know you could check if things have been pressed or are active in the interface? cheers for the reply

This is cool. any pointer on reading for resources on how to manipulate houdini's interface like this? also did this bit of code ever get released anywhere? cheers Daniel

ah ok. so just do it manually. just didn't know if there was a more elegant solution. and you can set absolute reference with right-click. thought there might be a function for it. cheers for the help. D

Hi Everyone, can anyone give me a heads up on how to do this? if I want to set a relative reference I usually do something like this. node = hou.node('/obj/geo1/') p1 = node.parm('sphere1/scale') p2 = node.parm('sphere2/scale') p2.set(p1) but what if I want the path to be an absolute reference? cheers for your help.

Hi Alex, I did report a bug in the end, but got the bottom of this in with some googling, as support could not solve this. it is unfortunately a Windows problem if you are running the program in administration mode. Drag and drop does not work. cheers

Just wondering how you set the output transform of an HDA at OBJ level from a node inside the HDA. Iv done it before but i can not remember for the life of me? can someone shed some light on this? pulling my hair out here and cant seem to find any info on this at all? cheers daniel

Hi everyone, has anyone come across this problem before? been setting up a custom script for drag and drop via the externaldragdrop.py file. Now the weird thing is. it works on some machines and not others. works on my home machine, a colleagues home machine. one of the machines at work and two other and work is does do anything. Whats seems to be happening is houdini, is not even registering that a file is being attempted to be dropped form an external window. So the .py file cant be called? I can't seem to find any documentation on this either which does not help. all machines at work are running the same environment setup. any ideas?? cheers Daniel Happy new year to all

thanks for the heads up malexander. after a bit of tinkering, I did finally get it to work.... few things to look out for. in your list of file paths firstly you have to make sure each string for the file path has a space before. then I ran into the problem where it would not open file paths that had a white space in the whole path. so after a bit of reading, I think because it's a shell operation? I have to have the string encapsulated in " " . (please correct me if I am wrong on this) so a simplified version below import subprocess fileSequenceList = [' "tmp/tmp/box.001.bgeo"', ' "tmp/tmp/box.002.bgeo"', ' "tmp/tmp/box.003.bgeo"'] subprocess.Popen(['gplay', fileSequenceList]) if I run into any other hurdles. il post them up. cheers Daniel

Hi Again Bunker, thanks so much for your help. im still clutching at straws here. the function I'm building is basically being run off a right-click menu in a QT widget window. Don't know if that makes a difference. this is the last part of my function for testing purposes. filePath = filePath.replace("$F4", "*") command = 'gplay ' + filePath subprocess.Popen(command,shell=True) this is the whats my command variable prints like gplay C:\Users\Daniel\Documents\NodeShare\Geometry\moreframes\box.*.bgeo and it's still throwing an error. and yeah I am importing subprocess its at the top of my function. just get this error. hou 18 - python 2.7 cheers Daniel

Hi Bunker, thanks for the help. Nope, I am afraid that didn't seem to work. my evaluated end of the string looked like this when I replace $F4. /geometry/moreframes/box.*.bgeo Googling this I can't seem to find any info on this problem. when picking files manually I noticed it had the frame range in () at the end of the string. like (1-240) but i tried this also adding to the end of the string. but it didnt work. unless it needs to be in a tuple or something. cheers Daniel

this may make me sound stupid. but I don't know how to print the Kwargs? can you give me an example of how to do this. sounds super useful. cheers

hi guys, is there any reason why this would not be working. i could have scripted it wrong. I'm in hou 18. I cant seem to get it to work with $F4 in the file path. throws an error. can get it to work with single files. anyone got any ideas?

just so people know. I could not find a way to do this with the build-in functions in python 2.7. I had to download a library to do this. the Keyboard python Library to be exact. cheers

Hi Everyone. Has Anyone got any ideas on how to do this? or point me in the right direction of any further reading. Google searching is not coming up with anything. how can I return if a ctrl or shift keystroke is pressed when dropping files in my externaldragdrop.py so i can define different functions depending on modifier key pressed. I'm using the def dropAccept() does anyone know if this returns any other information other than files. I also cant find any information in the docs on this function. cheers for the help. Daniel
