When I looked for tutorials for Umake on Youtube,
i also saw tutorials for Sketchup 3D.
And i saw some similarities and so i came on the idea
that you could also use sketchup videos to pick up
a few tricks for umake.
This video by Timothee Meyrieux shows what I mean.
It is called " How to Concept Design Art using
Sketchup and Photoshop "
Concept Art Design
It shows some modeling tricks that can be used
in Umake in this way or slightly modified.
I recommend to slow down the video. Go to Settings
at the bottom right and select .25 speed. You can
also stop the video at any time.
Here is another one by Timothee Meyrieux
Isometric Graphic Design
Hope it helps, have fun with your
“maybe slightly modified” imagination
