The script there is for Fusion 5, here is a better version that works in Fusion 6:

Any ideas? It seems like messing around with pImageEmitter, UVMaps and ReplaceMaterial reveals lots of bugs or unimplemented situations.

But... Why not just do the dissolve between the big image and the little images in 2D and put that animated texture on the particles?

I would go for the UV approach.
that is pretty clever..
makes me feel dumb

i would not have come up with this on my own....i am still trying to understand the logic behind it....
question...since you are preserving some of the original particles UV space (not much..... but a small amount) doesn't that introduce some mapping errors
also...why do we need the original UV space at all in the merge? to my understanding what you where accomplishing was overwriting that original UV space with the one created by the BKGD tool? couldn't we just outright discard that original UV space information? why is it needed in the first place?

The problem is that the particles can only show either one bitmap or one color. The Rendered Gradient looks like single colors therefore you can only have one pixel per patch (disable Merge1 to see the pixel effect).
The real uvs on the other hand have the 0-1 gradients per patch but are all in local space from 0-1. Connect the Render3D1 to the Texture1 node directly to see the effect.
The trick is to divide the UV space to a fraction of patches add it. That's all folks. Probably a good trick to make a video tutorial from. I will do it. Now that ...
The BC_substractFraction is poop btw. Seems like it wasn't needed or there is a logical mistake. I did this in literally 5 minutes so excuse this flaw.
