Bomb crater decals

[stable briar]

it would be awesome if bombs like the MK-82/83 and hydra-70s created small craters where they land, or at least blacken the impact point to add more feedback and realism to the user

Pleasessss

This document suggests that a good rule of thumb for crater size is D[m]=0.8W[Kg TNT]^1/3 (+/- 30%). The variation accounts for soil type and conditions.

That results in
454 (500lb)kg 5m - 9m (contact fuse) 6m - 12m (delay fuse) average 8m

Not decals, but actual deformation pls 🙏 then we can bomb runways

[copper lynx]

This is... LIKELY technically infeasible. What baha could do is change the unity physical material similarly to how grass introduces bumpiness to aircraft suspension

But runtime terrain deformation is not... usually... a quick toggle

[proud wasp]

No it's fairly easy. Unity has support for real time terrain deformation, and even barring that it's a simple mesh deformation calculation and remeshing job

[copper lynx]

Support yeah but depends on implementation, since maps appear to be loaded from user generated heightmaps

Im saying there might be a custom layer or two we arent seeing

[sleek path]

a VERY basic heightmaping system too

[sand coral]

there's a mod that did it

so its far from infeasible

[sleek path]

Pretty performance heavy mod tho

[sand coral]

i mean im sure it could be optimised

it is made by someone who im pretty sure is an amateur

[sleek path]

Yea totally

[sand coral]

(not sure)

[stable briar]

I mean there are mods that also add orbital bombing, so baha…..

[sleek path]

There are mods that add nukes which are actually far to powerful to be fun

[merry wind]

vtol does not use unitys terrain, also unitys terrain isnt that fast either lmao

[merry wind]

the terrain vertexes have a spacing of about 50-100m from memory, resulting in any weapon with an explosion radius less than that doing nothing, and any weapon that does happen to hit a vertex causes a triangular dent

[proud wasp]

There's an easy fix for that though

[merry wind]

using decals/models and parallax shaders would be a far cheaper way to achieve much better looking craters

[merry wind]

also, wow, okay

[stable briar]

anything is possible, you can add literally anything to vtol

if the game will take it well.... well thats another issue

[proud wasp]

No, that's just achieving what "looks" like a crator, not an actual crator

[stable briar]

but might as well give it a shot

[stable briar]

I wanna bomb my way to china

[proud wasp]

Let's be real 99% of the reason peeps want this is to bomb runways, no fun if you can just taxi right over it

[merry wind]

that would be easier to achieve with specific runway damage models, similar to how KSP achieves it

[stable briar]

cluster bombs would be amazing with craters

[stable briar]

bombing one end of the runway, and a hole appearing on the other end wouldn't be very fun imo

[sand coral]

hey i wasnt sure

[merry wind]

thats why the ksp runway is in segments

[sand coral]

could do it how arma mods did before deformation became official

slap down a big ole 3d model

simple as

[proud wasp]

It's easy enough to achieve a proper simulation (albeit a rudimentary one) - it's just calculate the amount of displacement of terrain (take some static value that represents dirt or gravel or whatever), multiply that by the explosions energy, and displace vertices based on that

Hell even just perfectly circular holes that represent blast yield by size is good enough

[sand coral]

well, baha seems to not wanna settle for anything "good enough"

[merry wind]

this is why you cant deform the vertexes of the ground, i did have this working as a mod but i cant find my screenshots

[sand coral]

ah.

that's

yeah that's definitely a crater

[merry wind]

moving a single vertex creates a crater the size of a cityblock that looks like shit,

[proud wasp]

Subdivide the faces before impact

Turn a 100x100m face into 100^2 1m faces or whatever

[copper lynx]

Tell me you’re not a gamedev without telling me you’re not a gamedev

Yes a dynamically tesselated terrain would be cool, no, synchronization, multiplayer, collisions, and so much more would not be easy.

Decals with hitboxes might work. Above ground meshes that depict dirt built up in a radius around the hole might also be a good middle ground, and damaging segments of the runway may be reasonable, but deforming the terrain itself is probably hard. Almost definitely.

[maiden garnet]

vtol works on a grid/pixel system based off of 4(?) height maps, so deforming them on a small scale would be really hard with the current system

especially when there's buildings on said terrain

[sand coral]

i bring it up again

but

the (old) arma 3 system of "thing go kaboom? on what? yeah put model here"

it'd be (relatively, im not a programmer so dont quote me on that) simple

[maiden garnet]

a crater model that doesn't actually go into the ground would probably work

just a big torus around he explosion

[sand coral]

and theres other arma mods, mainly the one that adds trenches that checks the type of the ground, ie grass, dirt, stone, etc and changes the texture depending on that (cept for stone you cant dig that)

[dense matrix]

Arma 3 does dynamic terrain deformation *natively now 👀

[sand coral]

yeah i know

[maiden garnet]

he was saying before that

[sand coral]

this game has like 3 ground types

4

grass, stone, snow, sand

[maiden garnet]

ehh

[sand coral]

that's kind of it

[maiden garnet]

the tree areas are considered different

[sand coral]

oh and conkreet

it could just be bunched up with grass

[maiden garnet]

but there's also cities, farms, runways, bla bla bla

I think most things would just turn brown regardless of its original color

[sand coral]

runways and cities could be bunched up into conkreet

true, true

[maiden garnet]

bomb snow and it melts

[sand coral]

i've never seen it happen irl so i cant say nuffin about it

[maiden garnet]

concrete would be different, but there is dirt under ut

[sand coral]

true that

but yeah bomb craters would make for interesting pvp

i think it'd also be nice to make them removable using a trigger

like you deliever supplies with a 42c and it repairs the runway yk?

[maiden garnet]

Yes I love this

[sand coral]

it would make for some fun pvp

like you just fly low as fast as you can trying to bomb the ennemy runway to make their lives harder

[sand coral]

so yeah it is infact dirt

[maiden garnet]

it looks like bomb craters really are just divots

they don't really go up much

brown all around

this is a simulated bomb crater IRL

Goofy

[sand coral]

ah yes

crater

[maiden garnet]

concrete would be a lot different

shockingly, nobody was killed in this specific explosion thankfully

[proud wasp]

You're correct - I only do gamedev as a hobby (: I'm currently studying a bachelor's in software engineering/compsci and I've been doing software development for 10+ years now, throwing around baseless passive aggressive comments is pointless - I never said it would be dead easy, but considering baha is capable of modeling a dynamic EM spectrum, I'm sure he can manage some basic terrain remeshing

[copper lynx]

Valid / sorry. Similar status here man, I feel like we owe Baha the respect of at least acknowledging the difficulty of the ideas we present, and when people present difficult ideas as simple, it strikes me as disrespectful. That said, its not my job to police suggestions, and youre right, apologies
