Hello I'm using shapes (it's amazing) and I wonder if a prewarm function exists ?
Because the first time my line is renderer I got a huge lag spike.

Had the same issue and MoDDiB's prewarm approach works for me as well :)
Would be great to have a "Prewarm" or "Init" Method we can call, since ShapesMaterialUtils is not public, so I needed to adjust the plugin code

Hey thank you for you answer I will try it but as far as I understand I think it's the static ctor of the ShapesMaterialUtils class that cause this spike because all of these ShapesMaterials instanciation :

Just a call to a public class that call an empty Prewarm function

is enough to get a proper prewarm and avoid the spike.

I believe you can use Unity's warmup API for this
