Hello and welcome to StarMade,
This update is pretty huge!
There are wedges and spikes now available for any block that can be put into different shapes. Use the advanced build mode (press left control on win ('-' on mac)) to change the rotation of the block selected in you bottom bar.
The physics fully support the new shapes, and there is no extra memory, graphics memory, or CPU needed to handle them.
How it works is best described with a video
Have fun building!
Thanks for playing StarMade,
