Hi, a few weeks ago i started trying to implement a tessellated terrain on my school project, but after finally getting it working, i encountered some issues, first one is that there is a lot of cracks on my terrain, i readed that this is a very common issue, and also found some solutions, but i cant find any sample code, and i dont really understand or actually know how to code those solutions i found, so i really need to see how it works already coded and understand it better, and the other one is normals after displacement, right now im using a normalmap to get my new normals after displacement, but i dont know if it is a good solution, and after that i still cant find a good solution to recalculate tangents or binormals for specular using, any help would be great, thanks.
