Hi, I would like to update geodes. My intention was the following: I create an AutoTransform node as a parent of this geode and shear and rotate the geodes using the AutoTransform node. The operations are dependent on the camera. That's why I will use the matrix of the node-position relativ to the coordinate system of the camera to perform the operations.
