Which is the right way to setup an HDRI? in vray

Good Day.

anu po yung tamang hdri setup. may nabasa ako sa net. dalawa yung nabasa ko na tutorials.

1. vray material>HDRI>drag to environment
2. vray environment>select HDRI>drag to empty slot on vray material.

--- bali baliktaran yung steps... so which is the best and right way?
or their just the same?

thanks in advance po.

Sasagutin sana kita kaya lang mas trip ko na matuto kang magresearch pa.

Nasa manuals at internet lahat ng sagot sa iyong katanungan.

Remember there are two (well three) uses for HDRI images in vray:

1. As a Global Illumination Source - via 3dsmax Environment Slot or Vray's Environment Override.
2. It can serve as an automatic environment reflection source (when applied via 3dsmax Environments Slot) and as an alternative reflection/refraction source via Vray's Reflection Override.
3. And oh - you can now use it to map your dome lights ala Image-based Lighting.

Now I have given you the clues - time to do your homework.

sir wrangler ,

eto po.

nag experiment ako sa hdri... eto yung mga output.

NO HDRI


WITH HDRI 3DS MAX'S ENVIRONMENT SLOT >PASTE TO> VRAY METERIAL SLOT



WITH HDRI VRAY MATERIAL SLOT >PASTE TO> VRAY GI ENVIRONMENT SLOT



WITH HDRI VRAY GI ENVIRONMENT SLOT >PASTE TO > VRAY MATERIAL SLOT



Sir, tingin ko yung may best result yung 3ds max's environment slot to vray material slot.

good day...

sir wrangler,

(vray renderer) test render po. 1 closed room. wala po syang opening. at sa loob nito may 3dteapot na chrome yung material at sa loob my vray light (sphere-for illumination) nagsetup ako ng hdri. at yung chromed teapot hindi nagrereflect yung hdri(kahit check naman yung sa gi environment sa reflection at nandoon na rin na man yung hdri, at sa lighting nya walang hdri na mapapansin....

at para malaman... binoksan ko yung 2 sides na walls right at front... bali open na yung room at trinay kong magrender. at yung hdri nagrereflect na sya sa chromed na teapot at yung lighting nya mapapansin na rin na may hdri lightings...

conclusion>>> ibig sabihin ba nito yung HDRI ay nanggagaling sa labas, di ko alam term dito kaya eto nalang gagamitin ko, na hindi sya parang hangin na kahit saan lugar ay nandoon.?


ganun po ba talaga ang HDRI lighting?

salamat po.

They're both the same, the only difference is usage. You put the HDR imagery to 3dsmax' Environment Slot to "globally" affect GI and Reflections/Refractions

If you want to use a different background for rendering and would want the GI contribution to come from another HDR imagery, you use the Override Environment Slot of VRAY.

You use the Environment Slot of the material if you want a per material/per object control of the HDRI's contribution.

Imagine Image based lighting (HDRI) as a substitute for your environment. In your first example - the box is filtering and covering the image from being seen by the raytracer (kasi nga tinatakpan sya ng box).

Here's something quite related to how one might use hdri:

Good day.

sir wrangler,

salamat sa explinasyon... naliwanagan na ako... ganun pala....

salamat po.
