I'm seeing that coronascatter will be our "forestpack" in the future, and we'll have corona standalone apps which has VFB's postprocessing ability in 1.6 (I hope with render elements handling too), and there is a plan too that we'll have standalone DR which will do DR without max. with such of those features we will no need to spend more money to buy another plugin anymore.
the dev team they are just damn so cool :)
btw, I got a problem, everyday I work with low resolution monitor and without using windows scaling, and I just experienced that IR doesn't remember the last size / resolution, it randomly starts in higher resolution maybe it seems in full screen resolution, it makes the IR start very slowly. but I cant reproduce it and in every scenes it happened randomly I guess.
