bsundman posted a topic in HDK : Houdini Development KitHi Everyone, I'm having trouble understanding the soho_outputmode 0 soho_pipecmd process. I have created a script for my custom renderer which works using soho_outputmode 1. After initializing soho, It will read and translate the scene correctly writing it as scene.xml using sys.stdout to write to the soho_diskfile. I can then render that scene successfully using my command "render scene.xml" from the terminal. Everything works as expected. I run into problems when switching to soho_outputmode 0 and setting the soho_pipecmd value to "render". When I hit the render to disk button, I see in the terminal that the render command is running but has the error that it hasn't been passed any file. I would like to know what exactly is being piped to the pipecmd and how to get the render command to see the stdout as a file. The documentation I've seen stops short of explaining this. Any help would be greatly appreciated!
Hello! I am begining an MFA thesis to add additional support for renderman within Houdini. This involves heading into some really unknown terrirory for me and I am having issues finding a "map" of how Scripted Output of Houdini Operators are structured. Are there any resources out on the web or any recommened reading to give me an overall understanding on how the system is stuctured? James S.
Is there any existing functions for extracting the final Transformation matrix that used for a copy or an instance. I am aware of the rules that create it : http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=6679 but are there any existing python functions (or easy methods) that allow you to extract this transformation matrix from a hou.Point() Object ? Thanks in advance,
