Support for animation/transitions when setting data-driven paint properties

Nobody has claimed this yet.

Up until support arrived for data driven fill-color I generated multiple layers and styled them separately to achieve color reliefs. The data driven approach has allowed me to go from hundreds of layers to one, which is great!

One visual effect that I lost, however, is that when I used to change color on my previous individual layers with discrete fill-color values I got a subtle fading effect, which was quite nice.

Now, when updating the data-driven property with new stops/colors, the change is much more disruptive and some polygons are even non-visible for a short instant.

I understand that transitioning from one data-driven setting to another is a bit more complicated than doing so between two discrete values. I believe, however, that this should be possible in principle.

Have you discussed having data-driven properties transition smoothly as well?

Start by reviewing the issue discussion and the existing behavior for data-driven paint-property updates and transitions. Done means changes between data-driven fill-color stops or colors render smoothly without the disruptive update or brief polygon disappearance described here, with appropriate coverage added where the project’s current tests for this behavior reside.
