Question A question regarding Vertex displacement performance

Hey everyone

I wasn't able to find much information online about how vertex displacement effects performance in unity, so I come to you for knowledge,

Is vertex displacement is unity heavy performance-wise?

how does vertex displacement compare to other deformation methods such as joint driven or alembic?

Is it efficient enough for use in very optimized applications that need to run smoothly on platforms such as mobile and/or webGL?

thanks!

 

It depends on the particular calculations needed, but moving vertices in a vertex shader is very cheap. I'd say it is probably cheaper than other kinds of deformation, and is suitable for mobile.
