Hi All,

I am brand new to Houdini and loving the software so far. I've been testing the terrains functionality and it's incredibly fast and flexible. I do have one question regarding obj's though.

I am sculpting a hero mountain in Zbrush to be used in conjunction with a heightfield terrain in Houdini to add erosion, terrancing etc. In the release video of terrain tools it is shown that you can project a mesh onto the heightfield terrain and then apply all the nodes as you normally would with a procedural terrain generated in Houdini. However they use a testGeo node and I can't find anything showing how to set it up with a custom imported obj. So far I can see it is mentioned that it has to be set up with a SOP network but being new to Houdini I don't have a clue how to do this.

Please run me through the steps to set it up.

Thank you very much!

from zBrush - export your mesh as obj
in Houdini, place a Geometry Object in the network
go inside (double click, or select and press ‘i’)
there will be a File SOP there - replace “default.bgeo” with your obj file.
you'll likely have to scale it down by 0.01 - append a Transform SOP to the file node and in the Uniform Scale parameter put: 0.01
(I think zBrush uses cm, Houdini uses m, so your model might be 100 time as big as you want)

Thanks a million!!!!
