Houdini exporting & Triangles

Ok we must be missing something simple here we cannot export any of our buildings in houdini to torque, its giving errors about them being drawn with invalid primitives and switching to triangles.

Have you tried to change the primitve type from "Polygon" to "Polygon Mesh" or to "Mesh"?
When you do this you can change the "Connectivity" to "Triangles" in the geometry level.

EDIT: Or maybe you can use a convert node to convert the geometry type of your object but I didn't try this.

Ok we got that part figured out. Turns out you need a divide.


Now the problem is too many details for our model

Does "too many details" means there are too many polygons?
In this case try the "Poly Reduce" node.

Because of the way vertex indices are stored in the DTS format (signed 16 bit integers), there is an effective limit of around 11k triangles per mesh. You can of course have as many meshes as you like, so you can always split a larger object into multiple meshes to get around the limit.
