Euclidean transforms output Null by default?

Well, I agree with everything you say.
Indeed, as you say there are advantages that are not on a forum.

But what bothers me is the feeling of being handicapped.
I agree that there is a lot of very useful information in the videos such as: GLSL
But for me it’s useless (and I think a lot of people don’t have perfect English) (If only Youtube translation was an ideal solution).

This is why I very often comment on this issue of accessibility

I admit that if it was in my natural language, I would prefer this kind of format.
So other than saying “Hey! Not everyone speaks English!”. My posts are useless.
And I would have no choice, ask here to transcribe the information contained in the streaming/videos.
