Here you have two sides. On the left you can see the source image. That is our selfmade reflective sphere. Choose on this side "Mirrored Ball". Our destination image should be latitude/longitude, that we will load in our 3d software to use it as skylight.
When this is done, Save as-->My_HDRI.hdr
and choose a HIGH DYNAMIC RANGE RADIANCE FORMAT.
Congratulations, now you have created your first own HDR-Image.
Matching HDRI - Reflection
Before you start a new max scene file, you have to recognize one thing. You made your own HDR-Image. And this image, we will ned twice in max. Why ? It´s simple, we will need one for our skylight (global illumination) and the other one for the reflection.
With Vray you have the opportunity to use both different channels seperat. For this reason, make a copy of your first hdri, and name both with the following:
a) HDRI-Reflection
b) HDRI - Skylight
Now it´s clear that it´s the same hdri, but with an existing copy of it.
Start now your new max scene file.
Very important. At first we match the reflection. For that, open your Material Editor (Shortcut M) and load your HDR Image as Bitmap. You also could load it into a Vray-HDRI, but with the Bitmap you have the Output channel included, that we will need a little bit later.Get sure, that your Bitmap is loaded as spherical environment.
Also check that you have choosen Vray as your render. Before you can make your first test render, we have to make some settings with vray. I don´t make a special explaination for vray, therefore you can use your manual or the offical website of chaosgroup. I will show you in a practical way, how you can get photorealistic result.
Deactivate the default lights, and also the hidden lights.
Here an example for a fast setting.
