Hi Shayne, Thank you for additional information. I am developing non-viewer base application. I am just reading terrain file and then I am doing two computation. These are checking collision detection and intersection to learn terrain elevation. I have problem on collision testing on terrain for a ray. That problem is, i could not get all intersection points due to not reading all the terrain pages in osg. For example, I have got a line that will be used for collision testing on terrain and I know that it has 10 intersection points on terrain but when I check collision test after reading terrain using readNodeFile function, i get 2 intersection points result because osg knows only highest terrain lod page. The question is how can i say to osg to read all pages of the terrain at first time?
... Thank you!
