This function is for use with the Shader Functions and sets the MRT (0 - 3) for native level shaders (OpenGL ES, OpenGL, DX9, DX11).
NOTE If you have not previously set a render target with the function surface_set_target, using this function will silently (i.e. without any error messages) end all further code execution for the event.
NOTE MRT's are not supported on HTML5.
surface_set_target_ext(index, surface_id);
| Argument | Type | Description |
|---|---|---|
| index | Real | The render target index to use (from 0 to 3). |
| surface_id | Surface | The surface to use. |
Boolean Whether the render target was set successfully
surface_set_target_ext(0, surf);
The above code sets the render target 0 to the surface stored in the variable surf.
