3dsmax & Vray HDRI Setups
show user profile  krbendel
I know this is going to sound like a total noob question but
What is the best way to set up HDRI with Max and Vray?

Vray Light Dome with HDRI Texture & Vray Sun
Direct Light or Vray Sun with HDRI in Background>Environment Map
Direct Light or Vray Sun with HDRI in Vray GI Environment & Reflection Slot.

Is there a "Proper" way of doing this or are all methods valid?

Hi Keith.

I don't think it matters too much, though I think Dome light offers the most control.

If you have "fixed" or high quality HDRI file you shouldn't need a separate sun though.

Check out this tutorial.

all those methods are fine.

I do all my testing/scene setup with hdri in environment slots (instead of dome - renders faster and cleaner) and when im ready for finals I apply it to a dome and turn off the env lights. This is because I want the hdri as a vraylightselect in post.

Direct light is good for just a light direction without affecting the light color. Vray sun for something a little more basic/automated.

I also do as BishBash suggests and use the HDRI instead of the sun now.

Tip for setting your background color without affecting GI - turn your environment map override to 0.0. You can now set your background color to white/grey and it wont bleed in color from the 'white sky'. So

Thanks for the tips Ross & James.

I'm still using max 2008 at work! with Vray 2.
I've seen tutorials where they use the inverse gamma to sharpen the shadows from
the HDRI sunlight, but all I got in the processing rollout is a gamma option.
It does sharpen the shadows a bit but I can only turn it down so much.
How would you increase the light & shadows given from the HDRI image?

By the way Ross have you been to any good gigs recently?
I saw Sleaford Mods & Subway Sect quite recently.
Going to see a band called Fumaca Preta in September.

Yeah the gamma setting in 2 does the same thing. Adjust that id the best way to increase contrast. Of course the HDRI file is going to affect the how contrasty the scene is too, both in the quality and weather etc.

After pushing that a bit I'd do the rest of the contrast adjustments in post.



Actually can't remember the last gig I went to, maybe BadBadNotGood. Going to see Tigran Hamasyan and the Yerevan State Chamber Choir in October, really looking forward to that. Not the normal kind of thing I'd go to see but really got into him recently.

Sleaford Mods I am digging, might try to catch them live too. Seems they have exploded in popularity recently. Going to check out Subway Sect and Fumaca Preta now, not heard of either of those so thanks for that.

Love me some good music! :)

I've taken to boosting the sun a few stops in Photoshop, really helps to bring out the shadows and give Max a bit more help in determining exactly where the hotspot is.

Ross,
I've not heard of BadBadNotGood or Tigran Hamasyan and the Yerevan State Chamber Choir.
I'll have to YouTube them.
