  1. Whatever (doesn’t) happens here it doesn’t feel right:
    v4g-bugs-iobox-editormode

this is as far as I go now, maybe I’ll dig deeper later


#2

ad 1) the script region is marked as experimental. should we add a popup that you need to confirm when you’re enabling experimental nodes in the nodebrowser?

ad 2) that one is on our list already, thanks.


#3

yeah you can add a not to the right sidebar in the node browser I guess. It seems to be it’s just missing a DLL or a wrongly configured version mapping but I guess that’s the furthest from important stuff now, I’m actually writing my thoughts about more subjective/usability issues


#4

great, thanks. and keep them coming!


#5

hah found yet another one: I accidentially hit “Restructure Document” in SKShader forward patch at PerlinNoise, at 07_Gradient-and-Noise-Shaders help patch. and after VL froze for 20+ seconds it threw an exception:

actually this happens everywhere I hit layout -> restructure


#6

good find, that’s a devvvv function, shouldn’t be in release builds.


#7

I found yet another one, probably related to the restructuring thing one should not suppose to click. Now I can’t create any nodes: (restarting vvvv gamma fixed it)
