All white models. I used 3 lights, orange, blue and pale green to light the scene.
i would like to know how to scale grouped and single objects on XYZ at the same time so to keep the ratio.
Nice work! I really like the idea of the endless loop that you created.
As for your question regarding scaling, maybe this will help:
It makes me smile this project inside the project … !

This GameDevTv course on lighting is amazing. what I do is very simple. 3 contrasting lights, one back, one left and one right. every time the same for some great effects no skills needed.
Lighting is super cool looking! I also had the same question about scaling multiple things as once. So thank you for asking!
Hey did you find out how to scale down a group of selected objects yet?
