  1. Hey Guys! I have a pretty newbie question about some Python and HDA interaction. So in a nutshell I'm trying to create an HDA with implemented Python script which does the following: 1. I have an Original Geo, which is object merged in my HDA. 2. I select some primitives on my original geo (or on the HDA). 3. After I selected my primitives, with a press of a button on my HDA, the selected primitives will be added to a group's pattern parameter inside my HDA. 4. And of course it would be great if this could work with a relative reference, so if I copy my HDA multiple times it'll update the groups within the correct HDA. I have this code so far: import toolutils viewer = toolutils.sceneViewer() geo = viewer.selectGeometry() s = geo.mergedSelectionString() # How can I make THIS PATH relative reference? n = hou.parm('/obj/Colorzied_Geo_Asset_1/Colorized_GEO/group1/pattern') n.set(s) I put together a pretty simple example file and the hda, which will hopefully help you guys understand what I'm trying to achieve. In case my explanation is a little confusing. selectedPrims_python_problem_v001.hip colorzied_geo_asset.hda Any help or nudge in the right direction would be greatly appreciated! Thanks in advance!

  2. Hello, I am trying to assign a material to packed disk primitive. This was already asked here many times but still I am not sure about my current situation I have geometry with two groups, I want to assign two materials based on those groups. However geometry is quite heavy so it makes sense to load it as packed disk primitive so that viewport is fast and ifd small. This geo is part of a digital asset, digital asset contains shop network with those shaders. So I need a way to assign material using relative path. I tried it but unfortunately it doesn't seem to work. With absolute path it works as expected. I also do not want to unpack the geo inside asset, because then I would loose packed disk prim advantages. One solution would be to save it with absolute path and put shaders always inside /shop/... But if I could make relative material path assignment working, it would make my scenes cleaner as everything related to the asset is included inside the digital asset. Thanks, Juraj
