Thanks for your fast answer! It works very well! But... I have an other question about LOD-Nodes. I can use a LOD to display a Model with a specified distance. To calculate the distance the bounding-box of the model is used. So i can set a complete model visible or invisible.
Give it a way to calculate the distance between the eye-point and a single triangle from a model? LOD of triangles from a model? Thank you! Daniel Am Montag, 15.
