Can I use GrayCameraDataProvider Class in NRSDKForUnityAndroid_1.7.0

I’m trying GrayCameraDataProvider of the NR SDK Scripting API below, but it doesn’t seem to work from Unity.

How do I use GrayCameraDataProvider?

Hi, woods,

Unfortunately, the grayscale camera raw data and GrayCameraDataProvider has very limited access to some developers previously, and it is not officially provided by NRSDK right now.

Instead of implementing your own Slam, however, you can expect better SLAM features from Nreal, which we’ve always been working on.

Thank you!

will it be possible to track like AR markers reliable because image tracking is kinda sad right now
