Which phy make rigid body command should I use for making a matrix be a solid body? The idea I'm going for is to have a deformable terrain.

Nothing I say is intended to be rude. My autism means that I do not know what is rude and what isn't rude. I apologize if I seem rude. It is not my intention.

You can use the advanced terrain commands and do a "phy make rigid body terrain" command... which is built for using DP with large terrains.

Otherwise, if you want deformable terrain, rigid body will probably work with a matrix.... never tried it though. Don't know how updating it works.

Although a deformable terrain is neat idea, it's not practiced much because of complications it can cause to the environment and behavior of gameplay flow.

Well, for what I'm wanting to do, a deformable terrain would be merely icing on the cake.

Doesn't PhysX support dentable meshes?

Also, I don't like Advanced Terrain because you can't tile the texture on it. It's just a big, screwed up pixelated mass with a single detail texture on it. Detail textures for grass are totally inappropriate for dirt and vice versa.

Yes, but not DP yet. It may feature in the next update.

A deformable terrain is a tough one for physics, becase of the overhead of a massive amount of polys. The standard terrain rigid bodies are static for good reasons.

You probably need to think laterally. Can you make the terrain from multiple convex meshes? Can you limit the deformable areas? Can you limit the ways in which the terrain is deformed to suit the DP functionality?

That defeats the entire purpose of casual physics. For me, it's an all or nothing thing. I'd rather have the entire terrain deformable or none of it. It might sound tantrum'ish but it's not. There are so many games out there that don't have a deformable terrain, that one more won't make the world end.

Oh well.

The difficulty around deformable terrain is probably why so many games have barrels It gives us something to shoot at and throw around, and stop us noticing that laser guided missiles don't even make a dint in sand.
