How many people use Brute-force as primary bounce in renders???
Have been frustrated with using LC & Irrad as my GI setup lately, so I have been playing with BF primary & LC secondary. The difference in lighting and details is amazing and I long for the day when I can efficiently use this everywhere. I am sure you are all aware of the noise problems with DMC GI but I am starting to prefer some grain from this setup over a lack of definition in the LC & Irrad. [99% of my work is stills]
What's everyone elses take on the Grain/noise issue??? Have you had clients say anything about it???![confused](https://forums.chaos.com/core/images/smilies/confused.gif)
On externals I am getting away with as low as 12 subdiv but internals seem to need at least 50-60 subdiv [mostly for the flat white materials such as ceiling walls. Anything with a texture on it doesn't seem to need the subdiv so high as the texture hides the grain.
VLADO told me in a previous post that Vray will one day have per object GI subdivision controls so you can increase/decrease the rate to get the best results in much less render time.
PLEASE VLADO ! when will this be implimented????? As far as Vray GI goes I feel this is the major downfall in the current versions. The ability to optimise GI per object/material would make such a huge difference to render times no matter what GI engines you used, and I am sure that it would change the way we all work forever.
*Imagine if you only had a Global Subdiv setup to control all the glossy reflections/refractions on materials in a scene. Materials that only required say 10 subdivisions would all get 50 subdivisions due to that one material that you need high subdiv for. Now that would slow things down a lot wouldn't it!!
Any others out there agree/disagree???? Would like to hear your thoughts and if your keen your support to push the amazing Vray guys to make their fantastic software even better.
