The fact that other engines don’t support this concept is their limitation and not ours.
I do not criticize the concept, I tried to understand the principle.
What I’m trying to explain is that in the SDK or the JMB, moving light at the same time as an object is convenient in many cases.
I see the presence of LightNode which must certainly solve my problem.
Unless I’m mistaken, it’s a pity that it can not be used directly with the SDK and JMB.
