You are an experienced programmer and have a problem with the engine, shaders, or advanced effects? Here you'll get answers. No questions about C++ programming or topics which are answered in the tutorials!
I was wondering if the game engine will support height maps in the future possibly?
I also was wondering if there was a way I could get a non box shaped skybox I was hoping to create 2 spheres one inside another with the sphere that is inside the other to be mostly transparent and have clouds on it and the surrounding sphere to have a night to daytime transiton so that I could rotate each sphere differently to simulate day and night, while also making the clouds appear as if they move .
The skybox is just a box set to the limits of your draw area with the viewable side aimed inward. Just create a sphere the same way and attach it to the camera.
I highly doubt that the basics of a custom scene node is going to change so massively. Besides, you don't add the code for a custom scene node to the Irrlicht source.
I bet there is even a tutorial on the tutorial page about custom scene nodes.
