I'll show 8 simple step to do a HDRi rendering.
|Set the material M for GI Color.|
Set it to TexBitmap from the slide down on the left, and choose the material
the image file must be in .HDR format, usually about 50mb++.
which i'll provide the link for the images later in this tutorial.
set the UVW Type to UVWGenEnvironment, and set the mapping
type to Spherical.
|apply the same settings for BG color's material M.|
and because by using HDR image for the light source that are not as intense as
VraySunlight, we have to adjust the shutter speed much slower than previously set.
for this one i set it to 10.0 (400.0 for the previous setting).
|and then press RENDER and see the result.|
OK HERES THE THING THAT YOU NEED TO KNOW ABOUT THE .HDR THAT IVE BEEN
USING FOR THIS TUTORIAL.
the .HDR image should look like this when you opened it up in Photoshop,
usually the image will be in 32bit, which means that you can tweak the exposure of it.
the file size of the image is huge at least 40mb in size .
for this tutorial i use 6000x2900 image 50.7mb in size.
