I'm not sure how to reproduce at the moment but documenting here what happened.

I recreated a script into udon to move a object with the mouse position using a ray to hit a mesh collider.

Update () {

var ray = Camera.main.ScreenPointToRay (Input.mousePosition);

var hit : RaycastHit;

if (Physics.Raycast (ray, hit, 300)) {

print(hit.point);}

}

my first test did not work so i went into the graph to add debug logs to find where its breaking. upon selecting the name to add node nothing happened. i proceeded trying to see if i could add any nodes but nothing was added.

i restarted unity to see if it would be fixed. upon loading the graph it showed all the nodes i tried adding before all piled together and none of the previously connected nodes were connected. I deleted all the added nodes and added a debug.log to start testing. but then it started functioning as the udon program should of done from the start.

upon loading the udon program it reverted to having all the nodes i previously deleted back and all nodes unconnected. ( https://cdn.discordapp.com/attachments/436983428643291156/656036543839862795/2019-12-16_01-18-54.mp4 )
