GlennimusPrime Posted April 13 Share Posted April 13 (edited) I haven't had luck using these path expressions in Solaris. Are these not supported in the USD workflow? Example: if I have a prune node directly after the asset I'm wanting to prune, is there a path expression I can use in the Primitive Pattern field, similar to what I'd normally use in Houdini?

GlennimusPrime Posted July 24 Author Share Posted July 24 On 7/10/2025 at 11:57 PM, PixelNinja said: lopinputprims('.', 0) That seems to be the default expression in the primitives field and affects all primitives piping into the current node. Is there an expression to use that applies the operation to the first connected node only? Quote Link to comment Share on other sites More sharing options...
PixelNinja Posted July 24 Share Posted July 24 The second argument specifies which input. So 0 for first input, 1 for second, etc. Is that what you mean? It will also only affect the most recently modified primitives on that input. https://www.sidefx.com/docs/houdini/expressions/lopinputprims.html 1 Quote Link to comment Share on other sites More sharing options...
GlennimusPrime Posted July 24 Author Share Posted July 24 It seems for me everything above the node using `lopinputprims('.', 0)` would be affected. I've just updated to a newer version of Houdini and the expression does indeed ONLY affect the first primitive piped into the operator! Kind of makes this question redundant as all that was required was an update. Thanks for your help @PixelNinja 1 Quote Link to comment Share on other sites More sharing options...
