BP animated light flicker

hi there, I did a simple animation of point light movement and change its color as it is moving, but it flickers. If i disable color change node, it works fine. does anyone know how to fix this? thanks

You’re changing the color of the light every frame. Tick runs every frame.

If you want it to change gradually, you’ll need a timeline ( not Tick ).

If you want it to change suddenly per second or so, then take a look at timer nodes.

cool, thanks for the advice.
