WorldAlignedTexture

WorldAlignedTexture（ Globally consistent texture ） The tiling texture() function is used to tile a texture on an object surface in global space , This tiling is independent of the size or rotation of the object .

This function allows you to specify the direction in which the texture is projected , And by global units （ Not the percentage of texture size ） Make a proportional adjustment .

Because this function tiles the texture in global space , So we need to pay attention , Any animated object that handles textures in this way will have textures " floating ", That is, the texture remains in its original position , The object slides under it .

project	explain
Input
Texture objects （ Texture objects ）（TextureObject (Texture Object)）	Receive the texture to be tiled in global space .
Texture size （ vector 3）（TextureSize (Vector3)）	Texture size , With X、Y and Z Global units on the axis .
Global position （ vector 3）（WorldPosition (Vector3)）	Provide 3D The start point offset of the texture in global space .
Export floating point 4（ Static Boolean ）（ExportFloat 4 (StaticBool)）	Whether to use the alpha channel of the incoming texture . The default value is  false.
Global space normals （ vector 3）（World Space Normal (Vector3)）	Allows you to specify the normal direction of the up axis of global space , So as to rotate the coordinates used by this function . The default value is 0,0,1, namely , Up Z.
Projected transition contrast （ vector 3）（ProjectionTansitionContrast (Vector3)）	stay X、Y and Z When projected in the direction , This value controls the blended contrast produced when two projection planes intersect .
Output
XY texture （XY Texture）	In the global X and Y The result of projecting the texture in the direction .
Z texture （Z Texture）	In the global Z The result of projecting the texture in the direction .
XYZ texture （XYZ Texture）	In the global X、Y and Z The result of projecting the texture in the direction .

 

Please note that , Although the ground has rotated , But the texture is still consistent with the global coordinates .
