First let understand what is the HDRI file format:
HDRI (High Dynamic Range Image) It's a special image file format that also has light information in it. This way you can use it in Carrara (or other 3D software that supports this file format) to light a scene without using any other source of light. In the Movies, HDRI images are used to mimic studio lights to light a CG feature. This way the stage lights will match with the rendered frames and composition will be far better.
This new HDRI light set is to be used as a internal environment, like rooms or other closed places BUT Carrara can't render GI lights inside a closed object, so you will need to do a simple trick to use them in some cases: just delete or hide some roof or wall. This way the light from HDRI will enter the room anyway! Look the image below:
But you can use it to light external scenes too.
This pack was based on some simple light layouts like 3 point light and others, but in the end I needed to add some more sources to get better highlights in the objects. You can see an example from every file effect below:
Light 01 -
Light 02 -
Light 03 -
Light 04 -
Light 05 -
Light 06 -
Light 07 -
Light 08 -
Light 09 -
Light 10 -
Look how the light projection works in every scene. They create a totally new mood in every composition. You can get better light changing the Sky Light intensity in the Render Room (For Carrara users only), like in the image above that I use the same HDRI with the 100%, 250% and 600% value:
The Sky Light function:
Another thing that you can do to change the effect from the HDRI image is simply rotate it! Yes, HDRI are projected from a spherical source so you can rotate it in the Assembler Room or flip it. The figure shows the normal way (Flip Vertical, Flip Horizontal and none:
Here is where you can control the rotation and other things in Assembler Room:
