I have some image (png or tiff) with embedded alpha/transparent pixels. They are always displayed as fully opaque by the gdal driver.
I'm aware of the "opacity" tag for "image" but it change the opacity as a whole. And using the "transparent_color" tag does not fit my needs, as it leaves some nasty colored pixels around masked out zones (as if the image was anti-aliased by osgearth *before* alpha-test)
Did I missed something? (note I'm using a FadeLayerNode, if that helps...)
The FadeLayerNode isn't compatible with the multipass mode since the
FadeLayerNode expects multiple texture units to be used and in the
multipass mode only a single texture unit is used.
Preemptive mode isn't compatible with the multipass mode but should
work fine with the FadeLayerNode.
