I am looking for a way to crossfade between an image generated via AI and its successor.
I get a new image generated every now and then, upscale it via NV-Upscaler and after THAT has happened, I want fade the connected out, that holds the previous generation, to the new image so that the newly generated image doesn’t just “pop in”.
I’m quite unexperienced in TD and I can’t find a way. Isn’t there a switch-TOP for outputs? Or some kind of other routing trick? This would actually do most of the job together with a cross. It does need a mechanism to actually just update the currently not visible output, too. But one question after the other 
Already made some progress:
What’s left is the question on how I actually trigger the two cache TOPs.
The “Done” Parameter coming out of the AI-Comp is toggling between 0 and 1.
So this would be perfect for actually pulse the “Active” on the respective TOP, but I don’t know, how to get a pulse from “Toggled Up” and “Toggled Down” of the “Done”-Parameter.
Hi @kingkongsy,
good stuff, the channel you are using for the cross should be useful for the Cache TOP as well.
First you can use a Fan CHOP and set it to output 2 channels. It will take the inputs value and set the output’s value to one of the channel with the index of the input value. As you only want to only pulse a parameter, you can attach a Logic CHOP to the Fan and set the Convert Input parameter to On When Value Changed…

Hope this helps
