Object2Terrain Author: Eric Haines (Eric5h5); C# conversion by Jessy Description Converts an object mesh to a heightmap.
thank for yor answer Duck, I finally figured it out. I paste the code I used so that anyone who has the same problem can check it out. It is not that good but I hope it helps. Unluckily if you modify the terrain at runtime it doesnt reset to the original heights it had before you played the scene. Modifying terrain height under a gameobject at runtime - UnityAnswers
Messing with Morphs! (Updated with Face now)
Blend shape animation! Dunno. I suspect it's mostly because no one here has asked for it in the distant past when Unity first started out and that very few people here would have made use of it. Right now, I don't need it. I can get by with bone based setups. However, I WILL need it later on when my characters make use of the morph functions in my 3d package for both morphing and complex facial animation.
Tools & Resources » Six Times Nothing Six Times Nothing develop a range of in-house tools and extensions to the Unity Game Engine for use in our internal projects. We have recently decided to start releasing some of these tools to the Unity community for free. We're proud of the tools we have developed and have found them to be invaluable additions to our own projects and it's great for us to know that they can be useful in helping to enable other developers to create great games with Unity too. The first two tools to be released are the River Tool and the Road/Path Tool .
