In discussing Unity tags recently, I noticed that we don't yet have a tag for physically based rendering.
This is getting to be a popular feature in games/engines, showing up in Q&A here (34 posts so far containing "physically based rendering" and 43 containing "BRDF")
The techniques and terminology differ substantially from conventional lighting models used in games. I think this is a good candidate for a tag, as a topic in which one could be a subject matter expert.
The trouble is
physically-based-rendering is one letter over our tag length limit.
So, I'm debating between a few options:
pbris short & easy to type, but not as clear unless you're already well-versed in the topic's parlance. It's also not search-friendly: if someone starts typing "physically..." the tag search won't suggest
pbr(like how typing "ambient..." won't suggest ssao)
physically-based-renderkeeps the core meaning, but is a little awkward, since we never talk about a "render" being physically based, just rendering, lighting, shading, or materials. Maybe "renderer" since this can affect renderer-level details like what to include in a G-buffer?
physically-basedis likely to get polluted with people using it to ask about physics-based gameplay mechanics, rather than rendering.
Since this is my first tag addition, I wanted to ask for META's expertise so I can get it right the first time, and avoid making work for someone else to fix my tags later.
