If yes, can you point me to the docs?
It does !
Here is the latest commit on the subject :
Yes, transparency is supported by the material. You can make an object transparent in a few ways:
- You can set the ‘Opacity’ value on the material to < 1
- You can set the alpha value of the BaseColor value to < 1
- You can assign a image to the BaseColor value that has an alpha channel (like a 32bit PNG, or a webp with alpha).
const material = myGeomItem.getParameter('Material') material.getParameter('Opacity').setValue(0.5)
