@TheJAMESGM,

nice, I'll test it myself too as I have not adjusted my distance too far.

 

And would you like to share the timecyc you are using? It looks really nice.

 

And anyone managed to get the timecyc colors from the mobile version?

I'm aware the timecyc of the mobile version is identic to the PC version but I'm just curious about if anyone

has succeeded it.

 

But holey sh*t, did the alpha bug just got even more worse when using the mobile version??

Timecyc is from Flames "Endless Summer" mod, pretty nice.

 

And the timecyc you're talking about is the colorcycle.. I doubt anyone could convert it, from the looks of it, people would have a better chance making their own type of mod similar to it rather than converting.

And as far as I know, alpha is fixed on mobile. But no one knows how, apart from Rockstar that is. Maybe we can try to contact them.

 

But I'm sure that one day it will be fixed. Tomorrow, in 2 months, in 10 years, doesn't matter. It will be fixed.

2014 must be the final year for GTA SA to have fixed the alpha bug.

After 10 years it must be fixed. It's kinda crazy we still mod and play GTA SA like endless :p

Hi, sorry for the non-topic question, but what is the "alpha texture bug" you people are talking about? and why is it called "alpha"?

The "alpha texture bug" in layman terms is basically an issue with 2D transparent textures causing rendering problems at the edges of the texture, usually trees and other foliage, it's more noticeable at night.

 

And "Alpha" is the texture channel.

I think, we do not can fix alpha bug, because it is a feature which is peculiar to SA's graphic engine.

By the way, it seems to me that War Drum used their own game engine for iOS-version (in other their games they used own engine), because of this they change the texture format. Also (I could be wrong) they have reduced the size of the game with using aliases for textures - something like shortcuts or links (?) - to avoid repetitions. Shadows and reflection are also feature of another engine, we cannot port them, of course.

Alpha stands for the transparency channel, which is the fourth channel used besides the red, green and blue ones.

 

The fringing problem is there mostly because of the engine being unable to properly sort out which parts of the model should be visible or not when they have a transparent texture on it. The bug isn't exclusive to the GTA games (heh, I've seen worse, like in Gangstar West Coast when models that should've been occluded by alpha textures pop out of the scene), and it's more apparent at daytime especially when two transparent textures intersect with each other.

 

You can fix it with workarounds, as what Dexx tried to do in VC, but a real solution for it would probably be doing additional depth-related operations on the scene, which I don't think that would be easy.

Well the reason for the texture format change is because the game's running on a GPU that accepts a different texture compression format, which, in the iOS version's case, is PVRTC. I don't think that they used a different engine apart from the change of APIs to OpenGL and some platform-specific modifications.

As flame said, when he imported other characters models, the game crashes on cutscenes. Anyone has any clue about this?

You can't see that anyway in-game... at least I don't think.

 

EDIT: ok it does show a little bit but all I did was copy the texture in.

Yes, something like that, but I haven't found the skateboard icon on mobile.

 

Something interesting, I noticed the trees and palms are a more green in mobile, so I take a look at the textures. The mobile ones are 512x512.

I wonder if the higher rez trees will greatly reduce the alfa bug.

 

But the mobile shadows are darker to me than the PC. I forget which file controls their brightness.

 

Also, how much better are the high quality mobile cars. I think I have the PC ones as I'm on an iPod Touch 5g.

 

I have more quality 2048x1024 and full. And other trees.

Had a hunch they may have updated the poker card textures (since they always looked horrendous)...and indeed they have:

I'll try and whip up a replacement with them.

Do main characters like Sweet, Big Smoke, Ryder also have fingers? And can those files be used in PC version without re-rigging?

In "High Quality Radar", radar02.txd isn't replaced with a HQ one.

Is this also on the mobile version, or Snoops25 forgot to replace it?

Wonder if anyone here's up to the task of reverse-engineering the new DFF format for SA Mobile.

Wow, this is pretty amazing. So all these updates the mobile version got aren't present in the Xbox or PC version of SA? Is there a list of all the updates the mobile version got?

Loading as in what? The loading bar when you load a save? That moves depending on your FPS, so it's not the trees.

Any chance the colorcycle.dat file could be ported to PC? Also how about the detail overlays.

 

@Silent: Didn't you say something about VCS PC Edition using a updated texture format? Do you think it may be possible to bring the mobile texture format to PC? That or get the game to read the file that tells the game what textures to add the overlays on so it doesn't have to be manually configured.

 

Also, is it possible to get reflections to look like they way they do on the mobile? ENB ones suck, and SAGFX has a few graphics bugs.
