I don’t manage to assign an IPO curve to a spot.
I used 2 ways unsuccessfully:
the first one is selecting the spot in object mode and pressing I to insert a keyframe but the available keyframe types are no spot relative ones but object ones (for example I don’t find the dist parameter or SpotSi…).
the second way is directly to create the curve uner the IPO graph view. I selecte the spot, go to IPO graph vieaw, I select Lamp as IPO type, then add New, but I got a message then telling that there is no active IPO curve.
Could anyone explain me?
In fact, I think I don’t understand enough the relationship between an object and an IPO Curve.
Yes , I’ve just seen it under the IPO graph view!! Thanks.
But why, when the spot is selected under Object and then pressing the I key, don’t appear the channels relative to the lamp like Energy, ?.. Only the channels relative to an object are available;
If you want to use I-key to set keys for lamps, you have to be in the Lamp Buttons context (F5 with lamp selected). Point the mouse cursor at the Lamp panels and press I-key. However, this way you can only set keys for RGB, Energy, Spot Size, Offset, and Size [actually I don’t know what these last two mean relative to lamps–anyone?].
You can create any IPO curve in the IPO editor by selecting its name in the right-hand column, then using Ctrl-LMB to create the points on the curve. To fine-tune positions of the points, tab into “edit” mode in the IPO editor window, or use N-key to enter coordinates manually for a selected point.
Edit: Found answer to my own question above - Offset and Size refer to dXdYdZ or XYZ size of a lamp’s texture.
