i just update FP yesterday and it seems to be working. at first i covers my entire area, but then i tick-on the "enable on Viewport/IR" option with "cameras and perspec" selected from the drop-down list. my active viewport was the camera view. so is that what you are saying above? - make the camera view active viewport and then tick that box and choose camera/prespec?
No. The "Enable on Viewport/IR" just defines for what views Forest will use clipping. Usually you want to set "Camera" or "Camera/Viewport".
Once set, when the ACTIVE view is of this type, Forest updates clipping for that view.
For example, if you want to preview clipping for "Camera01":
a) Set "Enable on Viewport/IR" to "Camera" or "Camera/Viewport".
b) Set "Camera01" as active view.
c) Clipping is assigned and updated for "Camera01", and result is displayed in all viewports.
You can modify or animate the camera, but not change the active view. If you swith to "Camera02", clipping is updated for that camera.
anyway - so you just got rid of the "auto-assign camera" and ability to manually assign a camera? like others, i've liked how that used to work in older versions.
We switched to this method and removed the old "Camera" parameter for several reasons:
a) It was causing a performance hit, because once "Camera" is assigned, any change on the camera object triggers a Forest rebuild, even if clipping or viewport preview is disabled.
b) "Auto assign to active view" was not working well with some render modes. This feature was introduced on the initial Forest versions, but Max (and renderers) changed a lot since then, and it was not reliable anymore.
Now clipping values for render are not taken from the active view or camera (that's used only for viewport preview). It uses a different approach which works perfectly with all render modes.
