GP4 Track Editing - new new thread
Posted by markko
Totaly another thing : Why nobody thought about it so far ?
(yes, original grid jip mappings are somewhat also displayed on this screen)
Skids at will, track tarmac particularities, every lines you ever dreamt to add...Everything is possible this way, in hiqh quality and with no fade out/blurry effect with distance.
ps : oh and any color can be used...yellow, reb, blue...whatever.

Laurent, are these new objects on the track? Do they flicker or something?

They are above the track and they are not flickering because their mesh respects the exact track layout.

Hmmm, very interesting Laurent.. 
So, it's possible to do example skidmarks to track with object and DXT5 + Full transparency texture? (As i made tree shadows in Monza.. ..Oval bridge area.)

I thought of this before but never put it into practice... nice to see it works!
Another question... how much are they above track?

Well, using new flat objects over the tarmac is not new anyway and I did it yet years ago when I added yellow and white garage lines at Imola or the Sepang red and white pitlane line.
And yes they are using DXT5+full transparency textures to blend with tarmac texture.
The main difference with past attempts is that thanks to latest GP4Builder improvements, we can now convert the full .dat tarmac into its .gp4 counterpart. Thus, we just need to create the tarmac once again for any given part of the track and displace it around 2cm higher and we will get a perfect coat over the track, following banking and direction. Then, we can also easily change mapping of each track object applying a 0.1 scale effect, making a 10 sectors section covered by a single texture.
In the example above, I used a 256*512 texture for chicane skids and 256*256 for other drawings.
Using a single texture is better for long skids else you would need to create several textures that could seemlessly follow each other.
Having an exact replication of the track gives less flickering than before when we used squares above track sectors. The 2 faces of the square were often covering two or more tarmac faces and thus rendering engine was having trouble to know which face was front of which and it was causing flickering at long range as with the sepang red line told above.
The advantage of this method is that texture is covering the whole tarmac all track long if needed, meaning you can set melbourne numerous lines and get them in high quality whatever the distance. You can also add details like leaves in grass or so by recreating banks or verges instead of tarmac.
The only little drawback is that you need to play with transparence to blend with the tarmac and to still see shadows when cars are going over these textures. Anyway, a workaround can also be found for shadows...it would only need to recreate white line pattern in 3d in the .col. It's clearly not a solution that could be done right now but maybe in future.
In the meanwhile, skidmarks are not causing any trouble at all and can be set at will...even over kerbs

These are permanent marks.
Anyway GP4 also draws usual dynamic skidmarks.

Duplication of multiple objects is not currently possible.
But as for many missing multi selection options, you can simply create a new scene and displace all the trees you want to duplicate in it, then delete all scenes but the one with trees and save the file under a new name (else you will crush your track :/).
Now, reopen your full track and reimport your single scene (File menu/import/.gp4 scene) as many times as you wish trees.

With such objects like trees, bushes or grass I have another method.
I simply duplicate the parts of the object at first...not the object itself.
So if you have a tree object with one tree, then it has only one part...no you duplicate the tree let's say 5 times and move the new parts. Now you have one object with six parts...now you can duplicate the object and by moving it to another place you can move six trees at one time instead of dupliacting them several times.

Probably you will have to adjust the position of each part manually but that's still much quicker then duplicating single objetcs.
