Hmm…there’s a problem.
I also have to change the order of drawing triangles in Sprite3D… to complete the scene I want…
(Because the spirte image is upside down, the rectangle needs to be redrawn with vertex)
Vertex access is blocked in Sprite3D.
So I guess I’ll have to make it in MeshInstance3D…
Then I end up having to create something identical to Sprite3D (AnimatedSprite3D) that does the same thing.
Thinking about it, if I used ‘Flip V’ on the image in Sprite3D, it worked as I wanted.
I think it would be better to just use the method supported by the editor rather than directly modifying the projection matrix.
Even if I do that, I don’t think there will be any major problems with the work I’m trying to do.
Since I am not familiar with the engine, I need to get more used to how to use it.
Anyway, thanks for the help.
