Here is an easy way to model using transparency so you can see a
reference image in the background:
Make 2 layers.
In layer 2: Document/Import/“bkgrnd pic”.
Set Render/Flatten off.
Set Draw/“RGB Intensity” to under 70.
Pick a material with a transparency setting. Then set
Material/Transparency to 100.
Pick Tool/Zsphere. (Make sure draw size = 1.)
Now in layer 1 you can draw out your Zspheres and model.
Attached is my recorded Zscript showing it in action…
