It has come to our attention that changes to Mapbox prevent SideFX from being able to continue support for the SideFX Labs Mapbox tool.

As a result, we have removed this tool from SideFX Labs from all Houdini builds going forward. As mentioned in the documentation for this Labs tool, users of it are responsible for following Mapbox's terms of use.

We do not currently have an alternative to the Labs Mapbox tool, but we will continue to explore and develop workflows in this area that meet the requirements of the Houdini community.

For customers looking for terrain and elevation maps, here are some links to data with usage rights that may suit your needs: https://freegisdata.rtwilson.com/#elevation [freegisdata.rtwilson.com]

Bummer, I figured this was eventually going to happen. Thanks for the heads up and links.
