I will have to pull the data from an excel, so which way would be better to use and why?
Well, I suppose it depends on your requirements and use case. One thing that’s clear is that the dynamic texture will have a much lesser impact on performance than a mesh write. So, if you don’t need the 3D aspect on your text and if otherwise you can make it all work with a dynamicTexture, I’d recommend that.
what if the req is for multiple text with different instances on a ground?
Mesh Writer is an extension that allows text to be written in 3D letters, i.e. each letter is written as a 3D mesh. It is not suitable for your project as described.
