Let me see if I understand this article
<https://www.nzherald.co.nz/business/sir-peter-jackson-to-sell-weta-digital-…>
correctly: the part of Weta Digital that used to develop the in-house
3D graphics/effects tools that they use in all those movies is being
sold to US-based Unity Software. The part that is left will be called
“WetaFX”, and will become a customer of Unity for the use of those
tools, no longer doing its own development in-house.
By the way, I’ve been looking at the Unity site <https://unity.com/>,
and it looks like all their products are rentware (subscription-based).
