Need help to resolve bug with dirt dust and shadows
I'm pulling my hair out over this bug.
When I drive on grass/dirt patches, the dirt effects from the front wheels are visible through the car. There is a weird shadow that goes over the roof as though it is a flat shadow dust effect. It happens with any cars add on or vanilla.
I've tried removing different mods and using back ups. I've tried removing mods and loading up as vanilla gta but same issues.
Has anyone had the same happen to them and know how to fix?
stopped when it's fine.
Then driving with the bug
Further testing on a base game with no mods and even trying resetting graphic settings still have the same bug.
Using a 980 gtx
Shot in the dark, but needs to be ruled out anyway.
Try reinstalling your GPU driver in Windows Safe Mode using DDU (Display Driver Uninstaller)
If that doesn't work, try verifying the vanilla files integrity/delete them & go online to download new ones etc.
Then test vanilla (without any scripts installed). Best of luck
@a63nt-5m1th thanks will give that a try. Wouldn't trying to reinstall the gpu driver in device manager and reinstalling do that same thing. What will the safe mode option do?
DDU (Display Driver Uninstaller) requires you to run it in Windows Safe Mode so that nothing interferes with the uninstall.
It's much more than a simple GPU Driver uninstall. It makes sure no trace of any previously installed driver is left on your system.
First time I used it, it gave me an extra 14fps in GTAV, as my Nvidia Driver must have been funky somehow (even though it appeared to work fine).
Basically, traces of stuff can be left behind & interfere with performance/cause glitches/issues (like the one you are getting) & are sometimes not removed if using a standard uninstall etc. This makes sure that doesn't happen & guarantees you're in the best possible position to get a perfectly working & optimised GPU driver.
@a63nt-5m1th I've tried the DDU but with no luck
I've also decided to try and upgrade to windows 10 and have reinstalled GTA 5 but still the same even vanilla without any mods. I think i will just have to put up with it
So we're looking at demon possession then . That's annoying.
Try setting the ingame ParticleFX setting to it's maximum & see if that does anything.
If no luck there, try this:
or if not there try here:
Find the 'DISP_THRESH' values (there's a min & max) for all the 'wheel_spin_sand' entries (& maybe test any other sand/dust etc entries too) & increase them slightly. (vanilla is Min = 1.0 & Max = 10.0)
What this should do is move the dust particle effect back behind the vehicle (I've not tested myself, just going by what I found on the web etc). The higher you set the values the further behind the car the dust should appear.
As long as the dust you see is created by this effect & you find the right distance to move the front wheel dust to the position of the back wheel dust there's a good chance you can push it out of view.
It may look a little funny in video replays but if it works it should remove the 'appearing though the car' effect in 3rd person view while you're driving it anyway.
Obviously, we don't actually know what is causing the effect, so I'm tentative so say it's a definite fix, but it's certainly something to investigate
Also, if it does work, you may have to test other values/surfaces in 'wheelfx.dat' that are kicking up dust & edit them too (I'm not sure exactly which ones do what etc but they are named pretty sensibly).
Make a backup first, & then you are free to edit all values to whatever you like in one go & confirm if it does indeed work (try big values like Min= 20.0 & Max= 30.0 etc). Then go back to your backup & edit only the likely sand/dust ones etc
Let me know how you get on with that anyway, best of luck
From what I remember, the game just spawns dirt PTFX on top of vehicles when you're going offroad. It should also happen on an unmodded install in a similar vehicle.
Aye, it does also happen for him on vanilla
I no longer remember what vanilla GTA V was like. lol
At some point in the last ~5 years I have removed all that 'ghost mist' nonsense from my game
I can't diagnose this issue very easily as I don't get any dust appearing on the roof or behind the car (just debris/tyre spray & such). Was never a big fan of the clipping that happens when dust/mist just goes straight through your car (or the ground, like fog on the streets etc) so it all got removed at some point.
Finding the ptfx texture for the dust would be one way to tone it down.
As mentioned, it doesn't appear in my game, so it's either texture or file edits we're looking at most likely.
You are the man!
Didn't think of that, but I've changed the particle effects from very high, down to high and issue is no more.
I've done a youtube video which was going to be to show the issue but it's now solved.
It was a spot of luck, glad it worked
