What are Matrix Nodes in Blender 4.2???
In this video I'll go over the new matrix nodes in Blender 4.2 and I'll give you the basics behind matrices and how they are used to make transformations in Blender (and other 3D softwares).
This may be a bit more theoretical than you're used to from me, but I found it much easier to get into using matrix nodes when I learned the basics of what they are and how they work. So hopefully this will help you too!
IMPORTANT: there's a blank space in the video that is being fixed (but takes a while to process). If you encounter it, skip to 25:37 to continue. Sorry!
