As one of Vuo's developers, I work on Vuo's engine (the thing that makes compositions run), work on nodes, and write documentation. You'll see me on the forums answering people's questions about Vuo.
I enjoy using Vuo to make live music visuals. My hope for Vuo is that it will grow into a community of people of diverse backgrounds and identities making lots of different artistic, useful, unique, goofy, beautiful, crafty, wonderful compositions.
Estoy practicando para ser competente en español. Si publicas en el foro en español, trataré de responder en la misma manera.
I see you already found this other discussion about appending text, and the proposal of adding an Append option to Save Data.
The attached composition demonstrates accumulating text with an Enqueue node, then writing it all to file when you click a button. (An alternative to the Enqueue node would be a feedback loop with Add to List and Hold List, similar to the vuo.list > Shift Squares example composition.)
eseftel — For After Rain, you do need to change texture to texture2D. (You can post the crash report if you want, but I doubt we'll fix this since the issue will be moot soon.) For Magic Whale, change gl_FragCoord/iResolution.xy to gl_FragCoord.xy/iResolution.xy.
Bodysoulspirit — Whatever the Shadertoy site shows in the iChannel slots, you have to put those images/videos/etc. into your Vuo composition for it to behave the same as on the site. You can download a package of Shadertoy input files here.
