Did Rockstar do away with rain collision detection

[peter g]

Ive reinstalled the game and the latest patch and now it appears to rain under the rail lines in Hove beach when it didnt before, was this done away with for faster FPS?

[Sobek]

I've seen quite a large number of people reprting the same thing - rain indoors and the like.

 

Chalk it up as another broken feature for the next patch to take care of.

[Lollercoaster]

Yep, rain now falls right through concrete, wood, steel...you name it, the rain falls through it!

[McLovin2404]

Acid rain. Run for your lives!!!

[BKwegoharder]

This problem was here since 1.0.3.0

[john88z]

Rain Collision Detection is a rather silly word for it. Rain isnt that dynamic, although I could see how that would be a plus, there isnt any collision detection with the world. Anyway Im getting this problem as well just hopes it gets fixed instead of being left the way it is.

It will be. We still don't have a moon lol.

 

We all hoped for much (much?) more then what has happen with IV, but man this is their first go at this sh*t engine/physics wise (I guess). It's understandable in some respect.

physics are awsome in this game, and im sure R* will improve RAGE engine in many aspects

[azkay]

How amazing would it of been if they used PhysX when they made GTAIV.

[supermortalhuman]

No, it's still there. The collision of rain is greatly improved this time in that it interacts with the environment much more realistically and they have more control over it.

 

What you are asking about is CULLING and they still do it. There are a few some-odd places that are improperly setup though, and if you move around the area in question you may find that it also is not raining where it should be (hard to notice, but you can if you are standing in it), meaning that the cube that defines where rain effects should cull (under things) is there, it's just not aligned.

 

You should report this to rockstar and maybe they will move or place the cull object, or perhaps they will see this and do it themselves. It's not like it's a game-destroying bug or anything, but if they are still supporting IV, why not I suppose? I imagine they absolutely love working on this game, I know I love working with their games when they come out.

You do now that PhysX is just like Havok, right?

 

Only difference is that PhysX is hardware-based, whereast Havok is software based.

 

So PhysX basically requires a nVidia-graphics card to work, which not all people have. Some also have ATi-cards.

 

Therefore, a software-based physics engine is the best.

You know you guys really suck at giving error reports . Ok we need to make this as clear as possible to Rockstar about what is going on. I believe they have a strong interest in fixing this but they will need our help. If you are suffering this bug then post in here with as many details as you can such as hardware and settings.

 

It would also help if people could either a) post a screen shot or b) a small video of what is happening . Oh and keep the Havoc vs Physx's to another thread. Remember this is just to post a problem with the rain.

[davetheshrew]

pc in my sig, I get the problem to. I just noticed it while going under a bridge, i double checked by ggoing under it slowly.

[CharmingCharlie]

Ok I have had a play around with GTA 4 and to me the rain seems the same as it always has, the rain is clearly visible before going under the bridge but stops whilst I am under the bridge and starts again when I drive out of the bridge. I did a short video :-

 

 

 

Now there is mist under the bridge, is that what you guys are talking about ? I don't see no rain droplets though.

i think they might be talking about the mist as i just checked and mine is exactly the same as in your video unless theres something else happening here.

 

anyone who has the problem care to fraps a little video so we can clearly see ?

[peter g]

I cant figure out how to embed it but heres a direct link

peter g would it be possible for you to do a video of the rain whilst you are under a solid bridge, it seems to me that the tracks you are under would let rain through. I am no expert on rain but you can clearly see the sky through the tracks and that would let rain through with no problem.

 

So when you have a second try and do a video of the rain whilst you are under a solid bridge. Oh and to embed youtube videos you do this :-

would give you :-

 

 

 

I was wondering if you could tell us if you have ever modded your game at all (the same for everyone else posting in here). I am not doubting you, just trying to get to the bottom of this, the more information we have the more we can help Rockstar Toronto localise the problem and fix it.

 

 

[Spider-Vice]

The video you posted has sense. The railway has holes, which means the rain will enter below the rails...

[peter g]

 

 

Well, once the video is youtubed the drops are nearly impossible to see. Ill post a few screenshots later on.

 

No mods at all

The railway does block the rain, its the first place that I noticed that the bridges etc... blocked rain, it just doesnt anymore. I noticed last night that at night (game night) the railway was blocking correctly, Ill see if I can get it to repeat and post a shot.

I assumed the feature was taken out (or modified) for a FPS bump, like Morrowind.

No mods at all, straight from installation to 1.04 patch. I wish I could upload the bigger movies but theyre way to big (>700Mb).

Some people here obviously don't understand how R* makes maps so Ill say it again

 

MAKING RAIN GO THROUGH THE RAILWAY/OVERPASSES WOULD NOT INCREASE FRAMERATE.

 

Stop thinking of rain as how it happens in real life, it doesn't fall from the sky. Its blocks just like the buildings only made so that at certain times rain will fall. Its blocks. Its not dynamic. It doesn't know where to fall. Its blocks.

 

My only guess is Rockstar mucked about with the blocks that designate where rain falls, or they didn't change anything at all and its all in our heads. Your guess is as good as mine.

[CharmingCharlie]

How about you contribute to the thread then, show us some examples of what you are suffering. All I can say is I can see rain where I expect to see rain and I can't see it where I don't expect to see it. So help us out and post as much information as you can instead of getting a bit too defensive.

[Blackhand]

Well I can confirm, that it even rains inside my safehouse and inside buildings. However, I can't say for sure if it did this previously.

[CharmingCharlie]

Blackhand is it possible you could post more information abour your system, whether the game has been modded and if possible either screenshots of of it raining or preferably a video. So far there hasn't been a huge response about this "bug" so it may be that it is localised to a few systems. If we want Rockstar to fix this we need to give them as much information as possible.

[Spider-Vice]

its all in our heads.

I agree. With all this whining about Rockstar, people started to go crazy. My game is fine for example, I don't really experience that and with this new patch it seems to look better!!!

[BKwegoharder]

I recently had gone back to the Catalyst 9.1 drivers because I heard that the z fighting issue wasn't there in that version. Well it didn't solve the z fighting issue for me, BUT it did fix the problem with the rain raining while under abridge or inside certain buildings(like playboy Xs apartment.) But the thing is, I get like 15 fps less with those drivers on average according to the benchmark.

[oc student]

Maybe we should start a poll? I don't get wacky rain in my game.

[The Horror Is Alive]

Neither do I. Somebody's on the weed.

[blackindia]

I have rain inside, in Bohan and in Playboy X apartment. The other ones I dont know about.

I think BKwegoharder has solved the problem for now...
