I’m using quad mesh instances with a billboard material overrides to place icons in my 3D world. This works as desired: the icons maintain their size and facing regardless of camera distance and stay with their respective parent spatials.
However, if I change FOV, then the icons grow/shrink. My game needs to be able to change FOV during run-time without the icons changing size.
Does anyone know how to make billboard texture NOT change with FOV?
What I’ve tried:
Changing the scale of the MeshInstance to compensate. This has no effect on the billboard texture size.
Playing with the SpatialMaterial params_grow and params_grow_amount. This does affect the icon sizes, so maybe I could use it to compensate for FOV changes. However, it messes up the location of the icons. Specifically, a child MeshInstance with 0,0,0 origin now displays itself offset in location from its parent spatial (possibly in proportion to params_grow_amount). Well… I could add scripts to each icon trying to compensate for this spatial displacement, but this is becoming way to kludgy…
I greatly appreciate any help!
