how to fix this the mod works fine without moving anything but when imported with zmodeler and exported this line calleds not exported: env_factor i { 1 , 1 , 1 } which affects and makes the object not look chrome

I have already reported this to Oleg.
The same applies to the truckpaint.

Posted: **Mon Mar 13, 2023 11:16 am**

what exactly is wrong? There should be no "env_factor" and "fresnel" on material that has a .add.env in a shader name? this is a bit strange.
Or the "env_factor" is missing upon export?

Posted: **Mon Mar 13, 2023 11:37 am**

Looks like dif.spec.oclu.add.env had this option on export and dif.spec.oclu.weight.add.env missed it. It's now fixed, get an update.

Regarding "truckpaint" material - I can not locate any strict scenario when this option is added and when it is not. All combinations of materials (including .airbrush and .flipflakes version) appear with and without this option, regardless of availability of "texture_reflection" slot. So, I can't say when this option should be written when not. Are there any exact cases when this option being created by ZModeler caused wrong appearance of material?

env_factor is obsolete for truckpaint shader

Posted: **Mon Mar 13, 2023 1:46 pm**

So there should be no impact if it appears in a mat file? I've removed it from truckpaint export options, it will be in next update some day.

Download the game, import and export the chrome tank w900 accessory, that is, the fuel tanks and you will notice the error, the most important thing is that zmodelere does not export the env line in the named material

env_factor : { 1 , 1 , 1 }

Or how we add it in zmodeler as user defined options.

may you specify the pmd file name to take a look?

Posted: **Fri Mar 17, 2023 8:58 am**

name : chrome_plated_260.pmd

version game : american truck simulator 1.46

Posted: **Fri Mar 17, 2023 11:47 am**

It looks OK to me (tested in 1.47).
"env_factor" is added to every material with "add.env" in material/effect name.

Code: Select all

effect : "eut2.dif.spec.oclu.weight.add.env.tsnmapuv.rfx" {
	texture : "texture_base" {
		source : "/vehicle/share/textures/metal/chrome_base.tobj"
	}
	texture : "texture_oclu" {
		source : "/vehicle/truck/kenworth_w900/ao_shared.tobj"
	}
	texture : "texture_nmap" {
		source : "/vehicle/truck/kenworth_w900/normal.tobj"
	}
	texture : "texture_reflection" {
		source : "/material/environment/vehicle_reflection.tobj"
	}
	diffuse : { 0.211765 , 0.211765 , 0.211765 }
	specular : { 1 , 1 , 1 }
	shininess : 70
	additional_ambient : 0
	env_factor : { 1 , 1 , 1 }
	fresnel : { 1.000000 , 1.000000 }

}

where can I find the source of this information?

I have checked .mat files from game version 1.47 and "env_factor" appears on some of "truckpaint" materials randomly. Mostly on those with bump-map texture or with flipflake effect.

Posted: **Sat Mar 18, 2023 2:46 pm**

This is due to the fact that the mat files in the 1.47 Openbeta are probably not yet all adjusted.

Posted: **Sat Mar 18, 2023 11:28 pm**

this is also true to pre-1.47 files. some "truckpaint" have env_factor, another - don't. and quite randomly. Looks like the default full strength reflection env_factor {1,1,1} is not written, but if the strength is lower, then the parameters is created. just a thought.

in the shader_presets.txt file for scs blender tools provided by scssoft.

I did a quick research - following shader contains env_factor attribute:

Code: Select all

building.add.env.day
dif.spec.add.env
dif.spec.add.env.nofresnel
dif.spec.mult.dif.spec.add.env
dif.spec.oclu.add.env
dif.spec.oclu.weight.add.env
dif.spec.weight.add.env
light.tex
lightmap.night
water

following code is the truckpaint shader:

Code: Select all

Shader {
    PresetName: "truckpaint"
    Effect: "eut2.truckpaint"
    Flavors: ( "NMAP_TS|NMAP_TS_UV|NMAP_TS_16|NMAP_TS_UV_16" "SHADOW" "COLORMASK|AIRBRUSH" "FLIPFLAKE" "ALTUV" )
    Flags: 0
    Attribute {
        Format: FLOAT3
        Tag: "diffuse"
        Value: ( 1.0 1.0 1.0 )
    }
    Attribute {
        Format: FLOAT3
        Tag: "specular"
        Value: ( 1.0 1.0 1.0 )
    }
    Attribute {
        Format: FLOAT
        Tag: "shininess"
        Value: ( 250.0 )
    }
    Attribute {
        Format: FLOAT
        Tag: "add_ambient"
        Value: ( 0.0 )
    }
    Attribute {
        Format: FLOAT2
        Tag: "fresnel"
        Value: ( 0.2 0.9 )
    }
    Texture {
        Tag: "texture[X]:texture_base"
        Value: ""
        TexCoord: ( 0 1 2 )
    }
    Texture {
        Tag: "texture[X]:texture_reflection"
        Value: "/material/environment/vehicle_reflection"
        TexCoord: ( -1 )
    }
}

the actros 2014 painted mirrors till 1.46 contained old mat files with env_favtor for truckpaint shader. (/vehicle/truck/upgrade/mirror/mercedes_actros_2014/mirror_02.pmg)

if you search for actual shader infos for trucks, import the newest models (daf 2021 for example)

Posted: **Sun Mar 19, 2023 3:08 am**

In an unpacked base.scs from game 1.47 there are dozen of .mat files with truckpaint shader and env_factor still there.
models for volvo_fh16_2012, vehicle/truck/upgrade/doorhandle/renault_premium and some others. The .mat file is in new format ("effct":"eut2.truckpaint,..."), so these are newly-created files.

Does availability of "env_factor" on truckpaint material have any impact on shading in game? For example, if you add "env_factor : {0.02, 0.02, 0.02 }" - will it drop the strength of reflection to a very low?

Edit:

...because users keep complaining on removal of env_factor as it causes reflection to be full-strength:

Posted: **Sun Mar 19, 2023 3:22 am**

It's probably because they don't want to adjust the reflection settings in the game.

One has in ETS namely the possibility to change that there.
And the reflection is set but in the vehicle Reflection as far as I know?

Posted: **Sun Mar 19, 2023 3:24 am**

In old days of ETS, the relection strength seems like to be bound to specular strength and was masked by base texture's alpha. However, the scania cabin in example above uses "grey" color-texture as base texture (DETAIL) "plain_grey.dds" with white alpha. This is quite strange, as I do not see how the game controls the reflection strength over surface now.

Posted: **Sun Mar 19, 2023 6:35 am**

It was confirmed the "env_factor" parameter has no effect in game. This parameter is now removed from export of truckpaint material. The imported "truckpaint" material will have a constant 25% (64) level of ENVMAP texture (if any). Other shaders will import/export ENVMAP reflection level with respect to env_factor material parameter.

Posted: **Mon Mar 20, 2023 5:12 am**

Well I share so that the inconvenience I have is understood, when the object is exported it affects the material and those two lines that I indicate in the photos are not included in the material and it makes the chrome look opaque

Posted: **Mon Mar 20, 2023 5:40 am**

Are you sure you use version with the latest updates? This issue was addressed already and export of this shader goes with env_factor always.
Here's an example of the model in a question:

If now I realize that the software does not update automatically, I had to download manually and add my login

Posted: **Mon Mar 20, 2023 6:10 am**

it does update. however, if you are on version 3.2.1, it is no longer evaluating, only 3.3.0 is in the works. It is essential to run as Administrator for updates to work properly. You can copy ZModeler_profile.xml file from your current installation to newly downloaded folder to retain your settings (including account name / password) if needed.

Posted: **Mon Mar 20, 2023 6:23 am**

thanks problem solved

Posted: **Thu Mar 23, 2023 11:04 pm**

hey oleg on the latest update after i export with truckpaint and airbursh flag im getting flags : "AIRBRUSH" in my mats and its crashing my game!!

Posted: **Thu Mar 23, 2023 11:23 pm**

my bad.. fixed. get an update.
If you get options from user-defined window of material that you don't want to be included in .mat file, you can add them (comma-separated, lower-case) in Profile -> Editor -> Preferences -> Filters -> SCSPrism3D -> IgnoreUserOptionsList.
