I'm programming for a show and will have a mixed rig of RGB LED's and generic's running from dimmer's with gel's. It would be most helpful to show the beams for the latter in 3D view with an approximation of the beam colour. It doesn't have to be precise, but if I change it using Fixtures Setting > Color in 3D view it appears to change the head colour but not the resultant beam ... unless I'm missing something which is quite likely! It's logical in one way as the 'color' option always seems to change the colour of the casing, but its the beam positions and colour one really needs to see.
Thanks in anticipation ..... Robin
