Hi. New to Houdini. I'm doing landscapes and I'm having some problems with UV scaling. I have several landscapes/heightfields in different sizes (depending on how close to the camera) and I want to use the same material for all of them. How can I get a consistent UV scale, i.e. “real world scale”, without having to calculate sizes etc manually? In 3ds Max you can apply a UV modifier, set it to real world scale and you're good to go.

Hi,

Heigtfield are essentially volumes and their uv are all unitised.

If you are rendering the heightfields in houdini you can use a uvproject in the shader. That should behave just like the 3smax worldspace uv’s.

If you want to export the heightfields to a different application or if you just want to do a uv project on the heightfield itself, you will have to convert the heightfields to polygons.

Hope this helps

Thank you, that helps. I found the uv project geo node, but I didn't look in the material, I'm used to controlling UV's on the object, outside the material.
