SVG Export: if Visibility range is ON, transforms are not working

[pgilfernandez]

As you see I'm tinkering a lot with Friction... I hope all this testing, asking things and issue reporting don't annoy you in excess.

I don't know if "Visibility range" is supposed to work for animated SVGs but it looks like to work fine but... if you use it in conjunction with, for instance any transform animation, the only animation you get is the "visibility range" and the transform is gone.

Project file: svga_visibility_range2.zip

I haven't tested other parameter animations, but they might doesn't work neither...

There might be issues, I only use visibility range for video or sound.

Well, I found one, it is just to let you know. BTW they are not big deal as you can always play with opacity to bypass the visibility range feature 😉

I will look into this after beta2.

Slightly related: it looks like flip book groups are not animating either in exported svg

Several features in Friction are missing SVG export support. Not sure flipbook makes sense to adapt to SVG.

I haven't tested flip books but as @rodlie says this kind of feature is not aligned with web animation ones but it could be done with some time and effort...

Hi @rodlie,

Could you help me a little bit? I would like to get to the source of the problem but not able...
I know that the problem is related on how the SVG is built when using visibility range but the curious thing is that the visibility itself is correctly handle in svgexporters.cpp at SvgExportHelpers::assignVisibility.
I have this project:

svga_visibility_range4.friction.zip

I would say the solution is to find the place it decides to apply another transforms when the visibility range is on and then unable it as it would work properly if it does nothing. The point for saying this is that if the visibility range touches the last frame of the scene, then, it is exported perfectly! but if it doesn't then, the transform of the object is messed up... Pretty odd.

So, this doesn't work:

And this is how it should be:

But if you do this then it works:

Could you at least help me to figure out where is this happening?
