filtered bump and FG

Post by Fer » 05 Nov 2012, 13:54

Anyone having problem with elliptical filtered bump connected to the material port with final gather, take ages to finish process FG.

It start and stop, like it hang on something. changing the format or the compression don't help
but connecting it directly into the mia bump port work just fine, it's just not the desired result.

best is to use raytype node for bump and fg. load the bump add node, put in your bump map node in bump input and your illum node in input. the use a raytype node and put the output of the bump add in all inputs, except the photon and fg port. here you use directly your illum node as input. then set the mode for fg from eye to fg port and it should work.
i dont use the ellyptical filter that often because i use mip map textures in map format for all my maps.
