Faking Bloom effect for LDR render

Is there any technique to achieve that? , working with HDR killing performance on some android mid range gpus and I’m looking for anyway around to make it done


UP, looking for any tips really

mmm, have you looked into using the spiral blur node in a post process material? Its not cheap, but maybe worth looking into.

Or perhaps, you could use emmissive translucent materials, on camera aligned geometry, to fake the blur around lights and such?
