How to use HDRI and sun settings

ASGVIS Visual Artist & Trainer Fernando Rentas explains how to use the sun in combination with HDRI to illuminate an exterior scene and produce sharp shadows from the sun in this video tutorial.

This tutorial was recorded in V-Ray for SketchUp but also applies to V-Ray for Rhino.

**Fernando will expand on this tutorial in two 90-minute online training sessions! More details here: http://bit.ly/e9v4DL**

The main point in this tutorial starts at 8:20

which is:

1- activating the sun system in Reflect Color (to keep GI and BG color working with HDRI).

2- uncheck the Reflect Color box... kind of bug but seems to work.

3- done and render

Nice one! Very cool to see my model in action ;)

You can all get the SketchUP file and a 3dsmax file on my blog

I can't seem to get shadows to show despite using the reflect colour to activate the sun. The Shadows are activated in sketchup and TexSun options.  Am I missing something?

Thanks man, GREAT!!!

Hi there, Great tutorial. I'm using a HDRI scene of a road. The only way to have any shadows in my rendered image is to put my object on a plane or box or something. I tried to apply transparent material to it but it does not receive any shadows. Can you tell me if there is a way to have shadows visible on a whole HDRI scene (eg, road)?

Hi . Used the same technique in an semi-interior room with a window . Got the shadow produced by the Environment/Reflect Color on the left ( that’s ok ) but used a parquet floor with Fresnel reflecting the Hdri BG ( on le right ) and I don’t want that .

How I can get like my parquet reflect the “Environment/Reflect Color Sky” ? .

Btw it’s very hard to get the Reflect color Sky and le GI at the same position .
