Vray Light Animate on/off

[tONy31]

Hi trying to animate a series of vray lights in a office scene turning on from a value of 0 to 25......whats happening at the moment is not what i want as they gradually get brighter as the animation meets the keyframe and then dim back down, i want a direct on then off ! hope this makes sense...any help aprreciated

just change the keyframe type from bezier to stepped, then they will switch. or, alternatively, put the full-on and full-off keyframes 1 frame apart?

funny thing posting on here, as soon as i did this i figured it out...a moment of stupidness lol, thanks for the reply tho i changes the keyframe types.

i do seem to be struggling now tho calculating the lightcache on the animation...any thoughts ?

if youre animating lights or geometry youll probably need a new lighting calculation for each frame. i suggest you look at some tutorials, or even the spot3d website.
