ViroCore is quite close to SceneKit but lags behind in case of transparency rendering. This is visible in cases of multiple layers of transparency (2 or more) where sometimes the underlying layer has triangular artefacts or is not rendered at all (in RGB_ZERO or A_ONE modes). SceneKit seemingly doesn't show this issue in DualLayer mode (https://developer.apple.com/documentation/scenekit/scntransparencymode).
