HDRI set up

[jackieteh]

Hi i watch many tutorials on internet showing that the vray sample rate should not be all in red color like what i attached here,
may i know how get rid of this, is this my setting problem or the vray HDRI problem?

my current setting is as below:

adaptive DMC : min:1, max:6
DMC sampler: noise threshold: 0.005
vray dome light subdiv: 64
material subdiv: 8 to 128


i am using vray 2.40.04 and 3ds max design 2014

If you just want to get rid of the red, increase adaptive DMC's Max to something like 50. That allows the sampler to use all the samples it needs. There is a lot more to it than that though, and it involves other settings as well, like GI. This thread is a good starting point, http://forums.chaosgroup.com/showthr...ght=samplerate. If you need more help, post your GI settings, or even a sample scene.

thank you very much for your reply and the thread link, i will try to increase the DMC max to 50, see is this help to get rid of the red area, noise issue, fireflies in reflection issue, rendering time and etc.

my gi setting now is:

irradiance map: low, Hsph subdiv: 90, Interp.samples: 40
Light cache: 500, 0.02, screen

i will post the sample rate element once it finish render
