In this tutorial we will be exploring how to light a scene using a low resolution .exr with a high resolution .jpg as the background to limit resource usage and increase system responsiveness without compromising the quality of our finished render.

In this video I make use of the 16K EXR, 2K EXR and 16K JPG from Hdr Outdoor Residential Riverwalk Afternoon Clear 001

Note: We have updated all our HDRs with correct EVs so the multiple + add node trick is not required anymore. Simply plug the Environment Texture directly into the Background shader and that's it!
