I really love bifrost but I think it really needs picture reading nodes and if possible some form of writing images. The current option of writing to color sets causes many issues with complex scenes and fx, and often times requires you to upres the two way higher than needed just for the effect, causing the entire workflow to slow down with complex rigs and models. And writing to images would be incredibly powerful and allow for even more complex behaviors like creating animated burn/ignition maps to then pipe into aero and cut out the need for another software for video creation. It would also be handy to be able to reference it in Maya much like converting the bifrost mesh into a Maya mesh and allow us to be able to use it directly in hypershade. I could go on for hours though about how useful it would be not only for fx but also for things like sampling the model in uv space and writing values for curvature maps or even exporting normal maps as well as even more obscure options like 2d liquid simulations, slime simulations, and way more!
