Few weeks ago I made a Lego tool in Houdini. Decided to upload it here. Cheesy presentation video and piano music included.
Once you know how it works a Lego tool is something that's pretty simple to do and I recommend everyone starting out in Houdini to try it.
My tool also supports different kind of blocks as opposed to only one kind of brick that gets copied on all the points.
I'm gonna make a blog with more details about it.
The cathedral model was downloaded from 3D Warehouse and made by Chris D.
