Generate a Animation keyframe from Matchbox PopupEntry

Flame Matchbox

Is anyone able to generate a keyframe from a PopupEntry menu item in a matchbox?

Even just a simple 0/1 entry.

     <PopupEntry Title="A" Value="1">
     </PopupEntry>
     <PopupEntry Title="B" Value="2">
     </PopupEntry>

Don’t think that’s possible.

Matchbox is not generic scripting, has no python access. All it can do is manipulate pixel values in a GPU texture.

I’ve suggested for a while that we need generic python nodes we can script. A long way away from that.

Many years ago there was this lovely feature in lightwave where you could generate a procedural texture, which would animate just about anything, including other textures.
Lightwave also had sliders in a hud, so you could animate said procedural textures directly in the viewports.

Support for animating popup in OpenFX was added in Flame 2025.1 for plugins that specify they want their popup to be animated. But this functionality was not added to the Matchbox API. You can add your vote the General Improvement FI-02157 on flame feedback.
