I got a new 3D software.
I am using e-frontier’s Shade for a long time. That is poor in making a UV map. I had to use Hexagon together.
The new software should have solved all. It has very many functions and tools. But they are too many to learn. I spent many hours constantly referred to the help files, and got tired.
I made a model by my familiar software after all. But, I may still continue useless resistance. And much time will be wasted.
