Configuring smoke for diesels

[whockin]

I am doing up some eng files for diesel locos and have played with the smoke color. The density of the smoke works but the color stays the same. All black for both regular smoke and transition smoke. Has anyone worked with this. Thanks.

Hi Andy,

I did tinker with the smoke when I received BLW's B&M BL-2s:











The exhaust entries were changed to:

Engine ( BL2_B&M_1551
Effects (
DieselSpecialEffects (
Comment (
the format of these little blocks is as follow:

offset.x offset.y offset.z
normal.x normal.y normal.z
width in metres

defining the offset from the shape pivot point
where steam / smoke should appear, the direction
it should go and the width of the nozzle
)
Exhaust1 (
0 4.7 -0.32
0 1 0
0.1
)
Exhaust2 (
0 4.7 -2.62
0 1 0
0.1
)
)
)

If this doesn't work out for you with the multi-tones of grey when down throttling, it may be my Global exhaust that was changed a few years ago, I can provide that file if you need it.

Hi Andy

Section 8.2.1.7 of the Open Rails manual covers diesel exhaust smoke colours.

I am using the new code for open rails to configure the smoke colors and density as shown in 8.2.1.7. The positioning is still in the msts code as above. I can change the density of the smoke and vary it with rpm and acceleration. When I try to change the color of the smoke, I still get all black. I don't think OR uses a texture like MSTS. Thanks.

The color codes are same as light codes but in a seperate Openrails sub folder for eng files. Similar to this topic shows difference.

I have been looking at the manual and I can't quite figure this out. Can someone provide a step-by-step process for the color changes?

Thanks

[UP_4848_Thunder]

Give an example of what your looking for if not in that topic link I provided.... like Color for RPM rev up loading and what color exhaust should be at a rpm stand still at load. Color is of a 8 digit code like MSTS light colors.

Example colors in red line of a seperate ORTS eng file from my test unit.

I have finally been able to see some color in the smoke. It is quite subtle. The color is still mostly black. I there a way to make it more grey.

[UP_4848_Thunder]

Try the last 6 digits of a color from here and use the 1st 2 digits for tensity of how thick or clear the smoke is as well as maybe glowing.

Another tip is don't include the exhaust settings of Max an Idle smoke rates in the ORTS eng file or smoke may be doubled.

[whockin]

The first 2 digits don't seem to do anything from "00" to "ff". The last 6 seem to have only a very subtle affect to the black. I tried everything from "000000" to "ffffff". I can see a slight bit of red when I put "ff0000" and slight blue when I put "0000FF" and green the same. The smoke is always black.

[UP_4848_Thunder]

What version of ORTS are you running an what color an exhaust is expected to be seen? I'm using the current X3404.

[whockin]

I am using 3403. I am hoping for grey smoke. The exhaust is too dark.

[UP_4848_Thunder]

Magnitude of smoke rates need to be toned down to reduce being too dark.
