Help with specular on exterior scene props

[Adorno]

Has anyone actually made specular look good on exterior scene props?
Maybe someone could share their settings.

I've made some wooden objects and use specular_shader_bump. Have tweaked the settings and it looks 'sort of' okay.
But there are two issues:

- It looks like big (square) pixels
- It reflects the colour of the ground - green hue, in this case. No spec. shader seems to avoid this.

Spoiler: Pixelated

Spoiler: Green hue

Spoiler: Settings and spec. map - texture size 2048 x 1024

Not sure how this will help, but have you tried setting spec RGB to 0.5 or 0 for each? Leonion gave that advice when someone had similar issues and it seemed to work.

 

[Adorno]

That obviously solves it since the effect disappears. But then there's no reason to use specular.

I did turn RGB down to 2 (from 3) and it's a little better, but only because it's less visible.

It's how that shader works; it picks up a green "ground color", IIRC.

 

[Adorno]

I'm afraid you're right. That's just how it looks on a 10 year old engine

You can edit the ground colour yourself in one of the .txt files (can't remember which, but it's not hard to find). Light blue or white look much better than the default radioactive green.

 

[Adorno]

It's actually very hard to find. I don't see it 
But it sounds like an interesting solution.

 

[Khamukkamu]

I think it may be ground_specs.txt within the Data folder

[xenoargh]

Yup, that's it.

Terrible idea, that; ripped it out of the shaders ages ago.

 

[Adorno]

So what part do you change?

So what part do you change?

you can see the description on the source file Ground_specs.py

 

[ShaunRemo]

Hey Adorno
you have probably tried these shaders?

standart_shader_bump_nospec_high_noterraincolor_Instanced
standart_shader_bump_nospec_high_noterraincolor

They say noterraincolor so I assume they dismiss ground ambient colour

 

[Adorno]

I know those, and prefer them. But they're both "_nospec_".
I just wanted to try and get a proper specular on scene props.

 

[Cozur]

Is it actually possible to change the ground_specs file?

 

[Ruthven]

Is it actually possible to change the ground_specs file?

Yes? But you are of course bound by certain limits - big one being that you can't add new ground textures. There are module .py files for all the Data files, you can see what is controllable.

So what part do you change?

you can see the description on the source file Ground_specs.py

The only part I can see is where the default colour is mentioned in ground_specs is in a comment. I'm guessing that removing the flag will remove the spec colouration, but to change the colour itself is in the shader, no?

 

[xenoargh]

IIRC, it's a constant in the shaders (but it's been so long since I axed that, I may be wrong).

I'm sure it's this in ground_specs.txt. I distinctly remember the endorphins flooding my brain when I realised the puke green underlighting was finally gone.

steppe 7 ground_steppe 3.000000 ground_earth_under_steppe 0.850000 0.730000 0.360000

The last 3 float values are R G and B respectively. Khamukkamu's post threw me off initially because they were all set to the same, but that's because he'd edited them. These are the native values.

 

[Adorno]

Thank you.
I tinkered with the numbers. Turns out it's only turf that makes the (green) "colour bleed".
