setUniformMatrix4(name, list, transpose)
- Transposes the way the matrix is read. By column or by row.
name:
- Type: string
- your name for the matrix
- Type: List [ 4x4 Matrix ]
- example: ([1,0,0,0], [0,1,0,0], [0,0,1,0], [0,0,0,1])
- Type: boolean
- True = row
- False = column
Note:
- Shaders work with Viewport Shading GLSL and Viewport Shading Multitexture.
- Shaders don't work with Viewport Shading Singletexture.
