Math.Unproject

Name	Mandatory	Description	Default	Type
⬅️ Input		Takes a float3 vector representing the 3D vector where x and y are screen coordinates, and z is the depth value in screen space.		Float3
Output ➡️		Outputs a float3 vector representing the unprojected 3D point in world space.		Float3
Matrix	No	The combined 4x4 view-projection matrix (sequence of four float4 vectors) to use.	none	[Float4](4)Var([Float4](4))
ScreenSize	No	The float2 vector representing the size of the screen or viewport in pixels.	none	Float2Var(Float2)
DepthRange	No	The float2 vector representing the range of depth values (near and far planes). Default is [0, 1].	none	NoneFloat2Var(Float2)
FlipY	No	Flip Y coordinate (on by default)	true	NoneBoolVar(Var(Bool))

This shard converts 2D screen coordinates back to 3D world coordinates using the inverse of a view-projection matrix. Both 3D and 2D coordinates are represented as float3 vectors (vectors with 3 float elements).It performs the reverse operation of the projection pipeline, including inverse matrix multiplication, and coordinate space transformations using the 4x4 view-projection matrix specified in the Matrix parameter and the screen size in the ScreenSize parameter.
