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
Dithering01.jpg
Then give it an 90° angle view
Dithering02.jpg
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
Dithering06.jpg
Select track, go near the borders. And take a look at the selection size. (in my case, 413*413)
Dithering07.jpg
Create a new picture with the selection size (for me 413*413)
Dithering08.jpg
then past the previous selection
Dithering09.jpg
then resize it to 512*512 (to import it in the TE)

open the lmap.bmp file
Dithering11.jpg
past the resized screenshoot
Dithering12.jpg
create a new layer
Dithering13.jpg
once done, select the lmap layer, select the all picture without the road
Dithering14.jpg
select yet the screenshoot layer and press delete.

select the all screenshoot layer and subtract the dithering part from the selection, delete
Dithering17.jpg
you know have the original lmap, covered by a little bit dithering.

select the rest of the cars and delete them
Dithering18.jpg
paint the dithering in tarmac1
Dithering19.jpg
yet you can´t see the dithering, because the track is in tarmac1 to, select the lmap layer and paint the road in tarmac2
Dithering22.jpg
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.
Dithering23.jpg
test the track in Generally
Dithering24.jpg
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

Thanks, I was waiting for the first impressions,

i call it dithering because people allways asked for it :)

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. ;)
