Hi guys,

Probably doing something wrong but on the 3rd lesson I'm trying to get the rock geometry to instance on a path after I rendered out the different frames of rocks and I've copied the expression exactly the same as the tutorial but it doesn't seem to be doing anything.

geo/rock_`padzero(3,stamp(“../copy1”,rockNum,1))`.bgeo

is the expression and I noticed on the video a comment about it also so wondering if there is a problem in Houdini 12.5 with this?

Edit here is the video:

http://www.sidefx.com/index.php?option=com_content&task=view&id=2166&Itemid=361 [sidefx.com]

around the 9-14 minute mark the whole process

Sorry i'm relatively new to houdini so probably a stupid thing but always good to get to the bottom of it.

Thanks,

Jon

just check Stamp Inputs checkbox on Copy SOP/Stamp tab
it needs to be on for Copy SOP to create variables per copy that can be used by stamp() expression

Thanks, thought it'd be something small just new to this!
