[SA] PS2 Grass to PC

[nyolc8]

I think too, that it depends on timecyc. Just waited in game from night to day and the grass color got darker and darker as daylight came.

 

ps2grass.asi: for me, I need to press f11 to get that script working, settings don't apply on start by itself.

[The Hero]

Huh. Any setting in particular? Seems to work fine for me. Maybe other mods are colliding with it?

[nyolc8]

Well, the one I notice is that I don't have fading until I press f11, I just get popping in gtass. But to be honest I don't remember I got fading ever. Btw I tried it in samp with grass.cs to get grass in samp. Maybe in samp it's popping... But f11 fixes it.

[The Hero]

So, I've reversed quite a bit of code now and I can't confirm that the grass color depends of the ambient color (but maybe I'm wrong). It does however depend on the day/night balance although I don't quite understand the formula. If I'm correct the resulting material color is Color*(x/30*(1-balance) + y/30*balance) where Color is the color from plants.dat and x and y are unknown 4 bit values, so 0-15.

In addition there is a function CPlantMgr::UpdateAmbientColor() which calculates a color from the current ambient color like this: 64 + c*2.5*255 where c is the ambient color. Maybe this was used on the PS2 so the code is still there but unused?

Just a little something, anything over 80 with farDist will increase grass pop in (default 60), seems like the limit is really small tbh

Edited February 18, 2015 by snoops26

[The Hero]

Maybe increase fadeDist?

Edited February 18, 2015 by The Hero

[Snoops27]

I am, experimenting not making much difference atm

 

These are my current settings atm, they seem to work quite well

 

backfaceCull=0

farDist=85.0

fadeDist=80.0

densityMult=2.0

Edited February 18, 2015 by snoops26

[The Hero]

You leave bacfaceCull on? Why that? Looks much better when its disabled, after all that's what the PS2 does

[Snoops27]

Oh in the ini it says "PS2 has it enabled and PC has it disabled" so I thought having it enabled would be better because of PS2

Edited February 18, 2015 by snoops26

[The Hero]

Oh damn, fixed it.

[nyolc8]

If I set fardist to higher than 80, then it starts to pop instead of fade, no matter of what else I set.

[El Dorado]

it crashes my game as soon as I step out of an interior

No idea, try with a vanilla game or so.

[El Dorado]

No luck on a clean game either.

I had a cleo memory write which wrote the fardist to 300.0 at game startup and that was the reason why it popped. So it works nicely now

[SilverRST]

 

I am, experimenting not making much difference atm

 

These are my current settings atm, they seem to work quite well

 

backfaceCull=1

farDist=85.0

fadeDist=80.0

densityMult=2.0

 

These settings seems to work for me aswell. Thanks.

I was really pulling my hairs out those grass kept popping in. Now they fade. But a bigger grass distance would be awesome.

Imagine GTA SA world full of grass already loading and see those amazing landscape.

[ric4rd094]

SilverRST - backfaceCull should be set to 0 as snoops26 and The Hero mentioned later

 

I'm wondering if it's better to use original plants.dat and densityMult set to 2.0 or edited plants.dat with densityMult set default (1.0).. Hmm ;D

Edited February 18, 2015 by ric4rd094

[The Hero]

Doesn't matter too much right now as the mod is not finished yet. I just found out why there are so few grass patches on the PC and what the PS2 does with the colors more or less.

What is that supossed to be? I already have set it to 0.

Excuse me for this dumb question but what is left to do with this mod?

[Inadequate]

For the new version of ps2grass.asi is the same link for download from the previous page?

There is no new version of my mod. I'm just starting to figure out stuff. The colors seem to be different from what I thought and I haven't looked into how the plant placement can be fixed.

Does the PS2 even has plants.dat? Perhaps if it does, it could be that file has different color RGB's than the PC's.

lol. the problem is: I not tested any version yet of the asi

The PS2's plants.dat is mostly the same. There is only one difference and this is due to the PS2 only using one type of grass model, the PC has four different ones (grass0_[1234].dff).

 

The colors just work a little differently on the PS2 but I'm quite positive I can figure it out (more or less).

Lol, I still use the first version which has a reversed 0 and 1 values XD.

Not really necessarily to update for now.

What in the world is that clumsy R* exactly trying to do?? Do those four plants even look different?

They look all the same to me, I imported the dffs in Zmodeler2. Maybe those four dffs has different colors?

[The Hero]

The grass dffs are the same on PC and PS2.

 

EDIT: haha, classic problem again, PC can't do what the PS2 can with color modulation. I will probably have to write a shader for grass.

 

EDIT2: got colors working (not sure if they're 100% correct yet), with unmodified plants.dat and plant1.txd:

 

Modded grass:

PS2 grass for comparison:

 

 

I also updated the asi.

@The Hero

 

What is the farthest draw distance limit for grass rendering? I would like set DD to 300 meters but game seems to ignore it.

That's probably because of the grass limit. I believe 16 patches of grass is the limit, I'm not sure if @The Hero plans on changing that, but I guess you could always ask @fastman92 to hack it for his limit adjuster or perhaps someone will hack it for Open Limit Adjuster.
