HDRIs Just Got Better
Why Blender Stack Exchange recommends it
Blender Stack Exchange answerers and askers point to it when HDRI backdrops need a usable ground, such as placing objects on an HDRI, building a dome, or fixing floating shadows.

What it is
A short Blender tutorial by CGMatter (Default Cube) showing how to project an HDRI onto a ground plane or dome so objects sit on a believable floor instead of floating in the environment. It walks through the node setup and scaling in Cycles.

HDRIs aren't really meant to be a floor, but CGMatter has a video on projecting an hdri onto an object here: [this video]

Finally made it work. Mistakes that I made on the way. As Gordon Brinkman mentioned in the comments Cycles engine renders HDRI texture out of the box. Meanwhile, any scene sets Eevee engine as the default one. After switching to Cycles I was able to see my HDRI texture. As it was mentioned by Gorgious, even setting the engine to Cycles the light seemed too bright so all objects inside the SkyBox looked like they were floating in the air without shadows. Unfortunately, the solution with MixShader didn't solve this issue, but I found a couple of tutorials that brought me closer to what I wanted. One mentions adding Diffuse BSDF before Material Output in the nodes editor. The second one suggest

Right now, I'm using Blender to render objects I drew (even with other softwares) in order to produce images (or videos) that help to understand the real size of the object in a known context. For example, say I have to draw a soap holder, I want to show it inside a bathroom to easily understand its real size. As far as I understand, to avoid to model and render every single item in a place HDRIs come to help. I'm aware they are not a "real" 3D model, in fact I followed this [this video] tutorial to create the dome (semi-sphere) where my objects can live. Still I have hard-time to make the scene realistic. The first question is: how much big should be the dome? Let's try with an example. I have t

I'm following a [this video] and can't figure out how to scale the lower part of a UV sphere as shown in the clip below. [LINK] The result I get is very different, and I can't figure out why. Can anyone here on the forum explain? [LINK] Here is a summary of the different steps as I understand Object Mode: Launch Blender and delete everything. Add a UV Sphere with 100 segments and 100 rings. Edit Mode: Select the equatorial line of the sphere using edge loop selection. Mark the seam. Change Select Mode to faces. Hover the mouse over the lower part of the UV sphere and press 'L' to select connected geometry. Set the Transform Pivot Point to 3D cursor. Press 'S' to scale. ... and the result can not
