Who says what I showed is the physical? You are looking at a visual road and visual curb. The physical curb will not have that tail. Nothing you see on a kunos track is physical. Remember that.
In that case do you need to manuall stitch the physics curb+road meshes together?

Thanks for your long answer. So I will add the tail on all my curbs. I already thought to it before but i believed it was a not a clean way.

Just two questions.
How can we have a look on how Kunos track are made?
When I have quad poly I can unwrap curved shape (follow active quad) but I can't use follow active quad when there are triangles. I also try to map from top view and Smart UV project but no results. How do you unwrap this part (see your picture) along the arrow to have a repeated texture ?

Sorry for my poor english but now I don't write english very often.

The way I map my tracks I only care about quads on the road surface and the initial edge between the track and the rest of the ground. If you look right off the curb it is still quads in that one section. The rest will be a regular projected from view map and applied to a google earth image so quads are not required.

Here is an example of a UV map of my NJMP Lightning.

And here you can see how the edge between the road and the grass is still in quads.This edge is what I use to blend between the road and the grass.

By no means is this the only way it is just how I have done it on all of my tracks. There are also a few ways you can examine original tracks but I will not explain them in this thread.

Ok I see. All grass is mapped one time. I understand more picture showing grass mask I can see on other topic. So this texture should be very high resolution (8K may be). It helps me a lot.

So now, I will rework my kerbs and continue to try to get clean road texture then get cool shader because I am really far far away to get the same results that yout photorealistic tuto (look my first post).

Hello people!

Is anybody know how to bake a fence net with transparency. I can get Normal, AO maps but i don't see how to get background transparent.
Here is the high poly model. Low poly model is a 3D a plane with net texture and simplified "IPN profil"

Then when you load the editor you can setup your material like normal and save as kn5. Now the thing that had me running around in circles is you MUST RENAME THE AC_CREW.DDS IN THE TRACK TEXTURE FOLDER!!!! If the texture is still there it will override everything and only show that one texture and not the ones from the car skins. So rename or delete that file to test in the sim.
When I delete the ac_crew.dds from the .kn5 the game reports an error and will not load the dds.

However, I have a problem when editing track .kn5 files with 3DSimEd3. It happens that suddenly the ac_crew.dds will not load from the car folders. Everythink looks ok when I have a view at the pit objects and materials in 3DSimEd3, but they will not load the ac_crew.dds from the carfolder. This may be an issue with 3DSimEd3 (latest version), maybe the .kn5 have to be imported with activated object nesting, maybe it´s the thing that 3DSimEd3 renames all object names to lower case, maybe I shouldn´t save the scene as .3se (its own format). I don´t know it yet.... :(

Anyone here with better expirience using 3DSimEd3?

Edit: Just did some testing. For the record: I imported the 5.kn from ks_barcelona to 3DSimEd3 and did the following:

1. Imported with deactivated objects nesting, saved it to the .3se format, loaded it again from this file and exported it to the 5.kn again. Result: No pitcrew at all.
2. Imported with activated objects nesting, saved it to the .3se format, loaded it again from this file and exported it to the 5.kn again. Result: Pitcrew with the ac_crew.dds from the 5.kn file, the ac_crew.dds from the carfolder has been ignored.
3. Imported with activated objects nesting and exported it right again as 5.kn file. Result: All is good, the ac_crew.dds from the carfolder has been loaded.

So it is most possible an issue with when the file will be saved as 3se. I will post this in the official forums of 3DSimEd3 as well.

I never said anything about deleting ac_crew.dds from the kn5. You rename or delete it from the texture folder which is something you use when you build tracks properly with the editor. I do not use 3dsimed for anything other than opening and exporting tracks. I do not care to support its use in my thread.

I searched the net about my problem and found this thread (which is public and no ones "property" btw). I thought that maybe some of the participated guys here knows about my problem. This is what forums are for...

I got you right with the track building process using the texture folder. But I thought your post is quite old meanwhile, and maybe AC changed some behavior. So AC acts different by loading from a folder compared to the .kn5, OK and thanks for the info.
Anyway, I isolated the problem as you can read above and wanted to leave this information here. Maybe it´s useful for anyone else.

BTW: I use a paid and licensed version of 3DSimEd3 for adding pits and grids to tracks for league use. If you just want to extract .kn5 tracks there are other free utilities out there...

I understand it's a public forum but it took a lot of time to put together this information and I don't care for it to become full of questions about 3dsimed. And yes there are other tools out there but for a while before content manager it was the only way to get shader information to find out how everything works.

Also if any of this information was outdated I would have updated it. Everything in this thread still works as posted.

I also update tracks for the league I am in but as I mentioned I only use it for the export process and have really come to hate how it is so good at screwing things up. I use it to get to blender as fast as I can.
