How to add a keyframe with no interpolation with the precedent frame ?
[i’ve edited the primary question, please delete]
In graph editor, with curve keys selected, choose Interpolation mode “Constant” ( menu Key --> Interpolation mode ), or with shortcut T
Ok, thank you very much
Changing the interpolation only works on keyframes allready set. But is it possible to tell Blender to ALLWAYS start with a given interpolation, say “Constant”?
Also, make sure you check “Restrict Animation Updates” in the render panel.
