Hello,
Sadly I'm experiencing the same issue and nobody has a clue:
It seems GeoServer transparency is just not working.

Hi Everyone,
I have a number of grayscale rasters with overlapping extents. When
incorporated into an imagemosic source the extents of these rasters
appear to clip with an arbitrary z-ordering, obscuring whatever data
happens to be in lower-level rasters.
In most/all of these cases the overlapping areas have data in one
raster and nodata in another so what I'd really like to see is either
(a) only data to be rendered (nodata to be transparent) or (b) data to
be stacked, since I'm confident merged results will generally dovetail.
To make this happen I've tried most of the imagemosaic options, including:
* BackgroundValues: Setting this to the nodata value (0) appears to
do nothing
* FootprintBehavior: Transparent causes render to fail
(java.lang.NullPointerException in BorderOpImage.copyRasterData)
* InputTransparentColor: Setting this to anything causes render to
fail (java.lang.IllegalStateException: Unsupported data type in
BaseSubmosaicProducer.collectGranules)
* MergeBehavior: Both FLAT and STACK appears to do the same thing
...without any luck. Styling the nodata value (0) to opacity 0 doesn't
help, either.
What am I doing wrong?
