Just something I did recently to improve my skills. Modeling was done in Blender and baking/texturing was done in Substance Painter
I recently started doing Architectural renders for a building design company in blender. (client's logo is removed for obvious reasons.) I Still haven't quite figured out the lighting yet, but it's certainly an upgrade from the sketchup monstrosities they used previously.
Look for some tutorials on YouTube. You can also try the free addon that comes with Blender called "Archipack".
I just started by doing some basic autocad drafting for them, then figured out how to generally translate the methods of making side elevations into blender, then offered to do it. the buildings themselves are actually really low poly, (usually each wall has horizontal edgeloops at the bottom of the door, the base of the windows, then at the top of the door, then a vertical edgeloop on the side of every door and window, though i only usually put detail into the side of the building that's seen.) since most things in the environment are shaded flat, the actual polygon density doesn't really matter.
This isn't actually a blender render, we use a program called Lumion, its what gives us all the fire, water, and other effects, though the model was made in blender.
im recreating (the interior) of my friend's rv in blender sorry if theyre too big i never used this forum before
