For example, I cannot access the quad or constant commands I used in beta version.
I installed the vvvv.dx11.core package and then activated Dependencies> .Net Nugets> VVVV.DX11.Core but it did not succeed. Did I follow the wrong path?
Betta uses own dx11 implementation, gamma uses Stride 3d engine. To get 3d rendering in gamma you have to download latest vvvv-gamma alpha version with Stride
