Hi, In Synfig we are considering to rewrite the current behavior of gradients animation. The current behavior is really user unsatisfactory when the gradient modify its number of stops along the time or moves it along the time. It seems (because I haven't deep look the code yet) that stops never are moved and instead of move the the stops the when the gradient is interpolated between two frames it just add as many stops needs to match the previous and next frames where the changes are made. So the extra added stop points match the color of the two extreme gradients at that position. So I'm considering modify the gradient interpretation when animated to allow move stop points instead of create new static stop points and change its color. I would like to have some feed back on anyone who has deal with animated gradients and how was the solution adopted. Attached the definition of an animated gradient in its xml file in Synfig (stop points are moved but Synfig creates new stop points that merges the first and second waypoint) As you can see, there is not information that specify if the stop points are moved or they are just created on the fly and its color adapted.I wold like to include some information in the file definition to tell the application to behave moving the stop points without change the color or add dummy stop points and change its color to match the gradients in each waypoint. <param name="gradient"> <animated type="gradient"> <waypoint time="0s" before="auto" after="auto"> <gradient guid="69ED6766CEA5C3EA94A650F755509AE2"> <color pos="0.000000"> <r>1.000000</r> <g>0.000000</g> 1.000000 <a>1.000000</a> </color> <color pos="1.000000"> <r>0.000000</r> <g>0.000000</g> 0.000000 <a>1.000000</a> </color> </gradient> </waypoint> <waypoint time="1s" before="auto" after="auto"> <gradient guid="C4E3A15BFF3FA7BEF9ED11B63F7C708C"> <color pos="0.316239"> <r>0.000000</r> <g>0.000000</g> 0.000000 <a>1.000000</a> </color> <color pos="0.683761"> <r>1.000000</r> <g>0.000000</g> 1.000000 <a>1.000000</a> </color> </gradient> </waypoint> </animated> </param> Greetings Carlos
