How to change HDRI with puzzles, and use a higher resolution?

Use the replace texture puzzle to change hdri.

I used it in this example: car configurator

I wouldn’t use high resolution HDRI for environment, but rather make JPG’s and map them to geometry that you hide/unhide. In the example given above i used a flat surface for ground and a cylinder for the rest. But the easiest is to use a sphere.

The geometry with with the images is in addition to the regular HDRI environment. They don’t emit light. Nor do they receive any lighting as I used a ‘surface shader’ (maya) and turned off ‘cast shadow’ on the geometry.

Create a sphere that encompasses the scene and cameras. Reverse the normals so only the inside of the sphere is visible using a 1-sided material. Map a jpg version of the HDRI on to the sphere and and position it to align to the environment HDRI so that the lights and reflections matches both HDRI and the sphere.

Edit: this tutorial shows how to project textures, in blender, to geometry in a scene from a hdri. https://www.youtube.com/watch?v=rrZiSwXoBVA
