This scene of a café is the perfect beginning for your next isometric project.

It comes with two texturing options: You can have it clean or damn bloody :D
To adjust this, you switch into the shading tab and select the room. Then select the red "blood"-node and mute it (shortkey "m"). Repeat this in the different material-slots until the blood is vanished ;)

The scene works for cycles and evee.
The objects in the room have grounded origins.

Please let me know, if you have any questions.
