Problem with an injected decal

[joker]

Not sure if there is some easy answer to my question, I'm a newb at PC stuff, anyway I got a football club badge in jpeg format that I wish to inject into Forza decals.bin
Here is a step by step of what I'm doing to try and achieve.
Open Photoshop CS (V 9.0)
Open jpeg image
choose index colour (windows default)
change image size to 126x128 (pixels)
change the background colour from 255/255/255 (pure white) to 0/255/0 (pure green)
paint in the remaining white areas which I wish to be clear in Forza
save image as 1 in .tga format
run autoclear
rename as decal001 (which is what I wish it to be)
check in forza decal browser that the image appears correctly
repack and ftp across to replace decals.bin

Now the problem is that a yellow colour in the image appears as a shade of grey, the pure green (transparent) appears as it should. The decal browser fails to show me any problem and I cannot see any problems when previewing my image. I think maybe Forza will only show colours it recognises from the pre-defined chart in the editor mode (I will post some images if needed, from PC and Forza)

Just wondering if anyone else has experienced the same issues.
Maybe someone has got a full colour selection as used by Forza (the exact values)?

More than likely I'm seriously overlooking something minor!

as I see it your not overseeing anything.....and I believe your right about your assumption regarding the forza palette only accepting certain colors....

I think its linked to the colors used......and I believe that forza only has 256 colors(in total)
where in photoshop you create your custom 256 colors......

then again if it couldn't recognise the color it would rather crash then assigning a color it self.

its very easy to see what your talking about of you try to do a pure white............which in forza will come off as greyish and for some reason slightly transperant it seems

Ok I have now got this one solved, there were multiple yellow shades which would show up in Forza and a couple that would appear as grey, so I made a note of where (roughly) the shades that would show were located. Then I applied that shade to the one which was grey in game. A bit more work than what I would have wished for, but at least the decal is clear now like it supposed to be.
I have managed a few times to lock out the decals/vinyls application of Forza with this problem, if the option was there then the grey shades are what I got, begs the question as to why the decal browser failed to recognise this shade of yellow which wouldn't be supported in game.

I think it has something to do with the forza decal browser being a program based on assumed values.....

meaning that they don't know fully what forza shows, but they managed make a program which would show something very close.

I found that more colours are unusable too, seems that many within the top half of my colour table are unlikely to be seen in Forza. Now if I change the values to make a new colour, then take the original values and choose a colour near the bottom of the table and replace it, then overpaint the old colour, it will become viewable in-game.
Strange but at least it works, just a pain keep extracting/injecting/ftp'ing/photoshop'ing.........is there a way to copy the values (keeping the colour) onto a new selection?

[Jake242]

not that I know of.........but if its troublesome to do, then how about making the troublesome area transperant and put a vinyl underneath in game......

it could be the answer.........im beginning to use 95% vinyls and 5 decals........since the final outcome seems to look better with vinyls.........ofcourse there can be so many different colors that it will be impossible to do with vinyls
