I assume you are using Forest Pack 7?
We recently identified a problem with several renderers that are using our API to add support for Forest Pack, including Fstorm (as well as Redhsift and Octane. It would appear that there is an incorrect value in the implementation of these renderers with the Forest API. Although it was not important with FP6, this value is critical for FP7.
This must be solved by the renderer's developers, we'll get in touch to let them know.
Meanwhile, in Forest 7.2.1 beta, we have re-introduced the "Camera" parameter. It lets you assign a Camera manually, instead to get the view settings automatically.
With a Camera assigned, clipping and the other features should work fine.
I hope that helps.
