Hi Chris:
We can sort this scenario out a bit more when you are back at your computer.
Here's my further interpretation of what you are describing...
You have 'custom' Autogen tree annotations placed for a 'custom' photo-real aerial imagery land class BGL made via SBuilderX, and are stating that those Autogen tree annotations are aligned with the real world aerial imagery tree locations as you intended.
You used a
Blend Mask and
Water Mask for the 'custom' photo-real aerial imagery land class BGL made via SBuilderX.
You made a
CVX vector polygon textured with Perennial River
water class for the
pond area which you placed
within the Geographic coverage extents of the 'custom' photo-real aerial imagery land class BGL made via SBuilderX, and it is intended to match the location of the pond within the real world aerial imagery texture.
You want the Perennial River water class polygon texture color for the
pond area to show through to the top of the 'custom' photo-real aerial imagery land class BGL made via SBuilderX using the
Blend Mask for transparency.
You also want the "
Hydro" water attributes of floating / splashing SimObjects, default FS "LivingWater" wave patterns (not to be confused with shoreline 'breaker'-type waves) to be seen, while also showing '
some' of the underlying aerial imagery texture for the
pond.
Your CVX vector polygon textured with Perennial River water class and having FS "
Hydro" water attributes for the
pond area ...is
not aligned with the underlying real world aerial image location of the pond.
You also placed a
boat on the pond; it is intended to be aligned with the edge of the adjacent pier in the pond area.
That
boat does
not render in its intended position (aligned with a pier in the pond area) when seen in FS at run time.
When you refer to "
plop trees", you mean FS default trees placed as scenery library objects using an object placement feature in SBuilderX or ADE, and which are compiled via BGLComp-type-XML and not placed / compiled as Autogen objects via the FS SDK Annotator utility.
Let me know if I have correctly interpreted your troubleshooting scenario when you are back at your computer.
