Photon emit radius

V-Ray V-Ray for 3ds Max Issues

In daylight system with vray sun I cant see where photon emit radius cover the scene for generate caustics.
In previous version of vray (1.5) I’ve been able to switch in vray sun view and perfect adjust photon emit radius.
xp 64, Max 2008, vray 1.5 sp2 64 bit…

The sun only shows the radius when it is selected, but when you use the daylight system I am not sure you can actually select it…

Best regards,

But Vlado, in previous version I’ve been able to change photon emit radius from sun viewport to know witch part of scene it’s cover by photons. Now I can see nothing from sun view?
