HDRI Render Studio
Grab this free HDRI Studio Interior

This is a HDRI I created years back in Blender. Since then I have kept using this for several professional projects in V-Ray, Marmoset, Arnold and even Substance Painter.

HDRI such as this is really useful for making not only reflections look great but as a image based lighting. And they work in virtually all major 3D packages.

This is now free in my Gumroad, so please grab it. I have also made a collection of HDRI environments.
