I haven't figured out what I dislike about Blender Geometry Nodes, but it feels so unintuitive to me. Don't think its a Blender problem, been using it for 14 years, but more of a layer of abstraction/convention from what you'd get in programming. Probably just haven't found the right access point.
Damn, even big ass molecules like this AN-PEP work with reasonable performance (in game, construction script is a bit slow). Collision needs to be disabled tho.
Turns out Unreal has a max loop iterations setting, which is probably a good thing, but left me confused for a while why my stresstesting wouldnt work correctly :D
There are C++ libraries to parse Molecule Files which would make building custom Nodes quite interesting, I just don't think I could've pulled that off in a reasonable amount of time.
After accepting there isn't a proper way getting Ball and Stick Models made with Molecular Nodes (thanks @bradyajohnston for this amazing Addon) from Blender into Unreal only using Instanced Geometry, I went with exporting the coordinates as CSVs and now rebuild the Molecule directly in UE. Worked out nicely!
Oh, looks like SteamVR broke, causing my controllers not to react to input. Took me a day, now fixed by setting beta channel to previous in Steam.
well at least someone reproducd the issue, although the solution was simple enough that I could have come with it
@HugoCortell might be caused by the denoiser 🤔
I would try disabling it and increase sample count if necessary
The UE Harmonix Plugin allows to create a MidiAsset Graph Input but you can't set it from BP 🙄
Learned a lot about Niagara building this proximity based Simulation (later visualizing intermolecular Forces)
The new Midi Setup looks like this btw, the Mesh is now encoded in the Velocity (T=Track, H=Height)
Small buttons are bit tricky, might need to check closest to finger before triggering?
Took me way to long to figure out that two AnimMontages need to be in two different Slot>GROUPS< to be played simultaneously heh
