osSetProjectionParams(integer projection, key texture, float fov, float focus, float ambiance)

osSetProjectionParams(integer linknumber, integer projection, key texture, float fov, float focus, float ambiance)
osSetProjectionParams(key prim, integer projection, key texture, float fov, float focus, float ambiance)

Sets a prim projector parameters, argument projection is TRUE(1) or FALSE(0). The prim can be the host prim on first variant, a prim on the linkset or a prim with giving UUID.

In last case Threat level is high and controlled by Allow_osSetProjectionParams. The other cases have no threat level check. Note that you may need to set the prim light also.

Threat Level No threat level specified
Permissions No permissions specified
Extra Delay 0 seconds
Example(s)
These examples will control the projection map in the host prim, a prim on the linkset and another prim identified by it's uuid.
