Currently the Geotiff writer doesn't support the Bigtiff flag when writing files with Jpeg compression. Jpeg is one of the better forms of compression available to create smaller files in FME, and being unable to make files larger than 4gb is a notable limitation. Tiling output files is an option, but it can also be difficult to determine eventual output file sizes inside of a running translation with disparate inputs.
Being able to write bigtiff jpeg tifs would be great.
