Post Skids texturing easly made with GIMP
I just found out (on my own in the case it was allready done) a easy way to make realistic skids dithering.

First of all, open your track
Attachment:
Dithering01.jpg
Dithering01.jpg [ 371.38 KiB | Viewed 1555 times ]

Then give it an 90° angle view

Then let AI´s make a race on it

When the race is finished, make a screenshoot, try to don´t have any cars one the futur dithering.

Also save your lmap.bpm file. it will be needed.

open your screenshoot in Gimp

Select track, go near the borders. And take a look at the selection size. (in my case, 413*413)
Attachment:
Dithering07.jpg
Dithering07.jpg [ 187.03 KiB | Viewed 1552 times ]

Create a new picture with the selection size (for me 413*413)
Attachment:
Dithering08.jpg
Dithering08.jpg [ 61 KiB | Viewed 1552 times ]

then past the previous selection
Attachment:
Dithering09.jpg
Dithering09.jpg [ 132.41 KiB | Viewed 1552 times ]

then resize it to 512*512 (to import it in the TE)

open the lmap.bmp file
Attachment:
Dithering11.jpg
Dithering11.jpg [ 184.31 KiB | Viewed 1550 times ]

past the resized screenshoot
Attachment:
Dithering12.jpg
Dithering12.jpg [ 487.8 KiB | Viewed 1550 times ]

create a new layer
Attachment:
Dithering13.jpg
Dithering13.jpg [ 20.02 KiB | Viewed 1550 times ]

once done, select the lmap layer, select the all picture without the road
Attachment:
Dithering14.jpg
Dithering14.jpg [ 180.16 KiB | Viewed 1550 times ]

select yet the screenshoot layer and press delete.

select the all screenshoot layer and subtract the dithering part from the selection, delete
Attachment:
Dithering17.jpg
Dithering17.jpg [ 244.7 KiB | Viewed 1543 times ]

you know have the original lmap, covered by a little bit dithering.

select the rest of the cars and delete them
Attachment:
Dithering18.jpg
Dithering18.jpg [ 234.05 KiB | Viewed 1543 times ]

paint the dithering in tarmac1
Attachment:
Dithering19.jpg
Dithering19.jpg [ 210.77 KiB | Viewed 1543 times ]

yet you can´t see the dithering, because the track is in tarmac1 to, select the lmap layer and paint the road in tarmac2
Attachment:
Dithering22.jpg
Dithering22.jpg [ 197.48 KiB | Viewed 1543 times ]

now you can see skids mark premade on the road

Save the image in .bmp, import it in the TE, reset your view angle, and save the track.
Attachment:
Dithering23.jpg
Dithering23.jpg [ 377.43 KiB | Viewed 1540 times ]

test the track in Generally

You now have a dithered track. Congratulation. Cocney will be happy :roflmao:


Final Tips :
- For more dithering, put more laps or more AI´s (for more in-game skids) before the screenshoot.
- Flat the track for the screenshoot, delete some objects if they disturb



So, what do you think about it?

Genius! maybe i will try to do this someday, seems very effective, but i rather stay on my paint dithering...

PS: i don't make dithering btw, i prefer to call it texturing :P

Post Re: Skids dithering easly made with GIMP
Very interesting concept, I'll try it once somewhere. :bg:

To add an under-line note about making dithering to be really visually effective - making it only in racing line in curves is usually good only for screenshots and first couple of laps, then it's completely covered by the worn tyre from cars of player and AIs, so the dithering looses big part of its visual effect, the track will look plain again during race.

So when used, this great idea should not be used isolated, but taken as part of wider concept of dithering on straights, on outside of curves etc, there it will stay visible, so the track atmosphere will stay somewhat visually coherent during whole race - player will keep in mind the dithering and somehow will imaginary feel it there during the playing all time no matter that eyes already cannot see it (otherwise it'll increasingly begin to look more and more boring during the race as an already once experienced visual detail is lost suddenly). BTW BBA and Otto are doing this with extraordinary high skill IMHO.

Of course here are various styles of road textures like plain colors and changes of surfaces, but there's valid the same about spreading various borders, concrete/tarmac patches, lines, cracks or dirt - if it'll disappear within few laps under worn tyre, it'll begin look as boring as never done, just observe Pahkasika how well he manages these details on his layouts. :)

Great tutorial. :) I've done this once with one of my tracks but that's years and years ago.

Btw, to be precise, dithering means mixing pixels of different colors to make a non-uniform texture, such as adding mud on grass. This is definitely texturing. ;)
