Quickest way to delete a polygon at runtime?

Hi,

I have a pretty heavy mesh from which I would like to delete a few polygons at runtime. As far as I have understood, the only way to accomplish this is to rebuild the mesh minus the unwanted polygons. Is this really correct? I am hoping that there is some more efficient method to do this than to iterate through the whole mesh and refresh it?

Thanks in advance!

Nope, that’s it. It’s not really too inefficient.

OK. Will continue to search though as on iOS it is a bit of a drain on resources.

I guess it will be more efficient if you split your model into two and add the “removable” part into another Game Object. Something like this:

My Mega-Zord GameObject
|- Static Mega-Zord Part GameObject
|  \- Static Mega-Zord Part Model
\- Removable Mega-Zord Part GameObject
   \- Removable Mega-Zort Part Model

This way, you can either delete the desired part or disable it.

EDIT: Trying to make the tree clearer

Thanks for the answer, although it's not relevant as I was referring to dynamically removing polys that are not predefined.
