Hi,

No data area of geotiff generated from 'HillShader' can't be shown as transparent in ArcGIS. If it's shown as RGB it contains ALPHA band, but if I choose 'stretched' in symbology, Alpha band is missing, nodata has been shown as black?

Anybody knows how to show nodata as transparent in ArcGIS if the hillshade output generated by FME?

You can use a RasterInterpretationCoercer to force the image to RGB

FME rocks! \m/

But I don't want RGB, Hillshade result has to be in stretched colour ramp from black to white.
