While playing GTA 4 and Dirt 2 yesterday crashing cars in celebration of upcoming Beamng (seriously), I realized some nice additions that can be made to the damage model/crash physics. Ideas accumulated from GTA 4 include: Noticeable car scrapes - In Beamng, I would think that the scrapes on the car can be acquired only through hitting/scraping on asphalt, hard dirt, and other logical places. It can just be a texture to keep the game as optimized as possible, but maybe the use (for higher end PC's) of bump map textures can be added as well for this form of damage. Dirt Splats/Smears - Same thing aforementioned except you can only get dirt on your car on offroad roads or areas. Ideas accumulated from Dirt 2 include: Realistic Offroad Rollovers - In real life, if a car is racing in a rally (for example) and manages to start rolling, the car's frame will dig into the dirt while it rolls and hits the ground causing more friction, which mainly means more rolls. In Rigs of Rods, however, if you roll on dirt you have even less of a chance to roll continuously than asphalt, but with asphalt's hard surface your car should slide more due to the inability to dig into the ground during the series of rolls. Heres an Asphalt roll over http://www.youtube.com/watch?v=hDo-sc0nYlc you'll notice the tires do most of the flipping for the car while in this rally http://www.youtube.com/watch?v=eN03FXZ6SHg you can see the car doing many more flips, it can very well be the speed and angle of the crash but if you look the car is digging into the ground mostly at the start of the wreck to get such violent rolls.
I'll answer these as best I can Noticeable car scrapes This is a pretty hard thing to do and has not been implemented as far as I know Dirt Splats/Smears Has already been added much earlier Realistic Offroad Rollovers That's part of the physics engine, cars will roll over like they do in real life.
Great ideas! I would really enjoy the dirt texture and the more realistic roll-overs depending on the surface you are on, even though the roll-over part might require more work on the map makers side to make depth to the map. I also found this http://www.gta4-mods.com/misc/hd-dirt-texture-10-f20172, it would be awesome if they would make these files easily accessible to modders in the BeamNG "DRIVE" directory so we could replace textures with higher quality ones.
They have? :O I thought there was nothing on dynamic texturing. Anyway, I know what you mean with the rollover; we would need a ground sort of digging system like spin tires for that..
Noticeable car scrapes - Planned & being worked on. Only huge problem with it is Dynamically Vertex Blending a Texture Layer Dirt Splats/Smears - Same as above Realistic Offroad Rollovers - Good idea. But I'll bet when the Devs start perfecting their mud physics, they'll make sure to get this in too.
We already have the differing depth for different ground models like dirt and mud, and vehicles dig in and react accordingly
Wow, considering those physics are already implemented i'm by far amazed at the development! You guys are doing great stuff, I hope to see some room for more effects like the ones mentioned later in the projects progression, nonetheless brilliant work! I really hope to see this used in next gen console games ^_^
Actually it's not dynamic, it's just a dirt texture over the car texture that Gabe was showing, I don't even know if it will be in-game.
Does it means it's something like spintyres and car will dig to "stop" in mud drived in wrong way? Do also mud or other surface like snow etc. "holding" wheels making stearing really hard for example when raining etc? Is it only 1 dust layer(material) blended with car texture? or I can define a bunch of files for litle and more dirty car? Is there terraforming wizualization (like spintires) or only "handling configuration file" for physic to drive on kind of surface. Sorry 4 my english.
Yes, you can get stuck in mud realistically. Sand and other surfaces also behave realistically. Snow is possible too. The terrain does not currently deform, but it may be possible. There is no dynamic dirt system yet (to make the cars get dirty).
Don't kill me for necroposting, but I have been searching for a good 20-30 minutes and have failed to locate the dirt texture "layer" for the ibishu covet I probably look pretty stupid asking like this but it's been probably 4 months since I last played this game and can barely remember anything
I think he means that the car won't dig into the dirt properly if you happen to be sliding on dirt, considering the ground is not deformable.
