I’m trying to import tree instances into Houdini but the point’s height doesn’t seem to follow the terrain. There is something up with the Y axis in the exported PLY file. It’s range is 0-20 but the range in Gaea is 0-150. Scaling the y axis by say 7.5 doesn’t work. The X and Z values are correct. I’ve set the point cloud scale to meter and made sure the Gaea terrain definition and Houdini terrain size match. Is there any documentation or tutorial videos showing how to import tree instances into Houdini?
Message to developers of Gaea: would it be an idea to add scale attribute to each of the points in the PLY file? That way you can replicate the tree size in Houdini.
