I exported layers from Gimp using a plugin , I exported the layers as sifz . When I open the file , layers look like in Gimp but I can’t animate them , I can move them . The timeline is missing . The image shows the missing timeline and the green / red guy . Here https://ibb.co/cqe10Q or here ibb.co/cqe10Q
Is there any fix ? It would save me a lot of hours of re scaling and moving and grouping the layers.
