Thanks for any help, hints or suggestions. Not sure if it would work in a callback script or something within the parameter dialog or directly as an channel expression.

I just hope to find a way to automatically create those important components so I can re-compose and new file name for caches and what not and extract the version of the scene file to match version of file caches to the scene file for example if changed. I hope this is kind of transparent of what I want to do. Multi line works as long as you only use strings. This award-winning and production-proven product handles the most challenging shots without the need for additional plug-ins or an army of programmers. Houdini Master is the most complete visual effects and animation solution available. My goal is to use this in a parameter dialog where I can fill a string parameter automatically with my shot name,Īnd a second one with my element name and so on.īut arrays do not seem to work as a string channel expression. SideFX Houdini Master v12.0.557 Win/Mac/Linux XFORCE. My hip file name is formated like this: MyShot_Element_Ī could define them as detail attribute and what not.

The idea is to fill a string parameter automatically with a part of the file name the attribute and wrangle world it's easy: I am trying to create an expression inside a string parameter and need some starting help: So i have ABC->shadingGroups (this is the key)->one material node.īefore shadigGroups we were using SPLIT node and recreating hieatchy based on material at SOP level. We even published this setup with all scripting to SideFX asking them to build it into next houdini release. We have one special node that allows you update groups, move pieces to different groups and not having any duplicity (in Houdini there is no easy way how to have one object in one group only without duplicity, which is essential for shading). With a help of friend, we come up with something that represents XSI/Maya workflow with materials assigned to groups. Tricky part is how to create (and more important update) groups and its material assignments. We are assigning materials with one material node and targeting groups. So after several years I have something, that works in worst scenario and never failed me.īad scenario for me is: 20k pieces, 150 materials, no usable names on objects. Sometimes with hierarchy, sometimes without, names, no names etc. My workflows consist of huge variety if ABC caches. Only way i was able to usably work was at SOP level. Houdini is super slow with heavy hierarchy or lot of objects.
