IBL/PBR Car Shader Assistance

So I'm just curious, how does it work on the McLaren? How is the two situations different? If there is any kind of workaround in my situation, I'll explore it. The one thing I don't have the ability to do is to add the wing to the WCCARBODY. Unless there is a really step by step mapping tutorial and if the texture could be 3072x2048, then maybe I would be able to do it LOL!

I just use the way I describe above, and... just for one car testing, And I haven't check another car, just test it.
For what I've done, just simply
1. add MaterialPath mapping in .gen file
2. assign PBR for those materials you want to in http://localhost:5397/materialeditor/index.html#/
3. press save to dev when you done. just don't use carpaintor in dev mode I think.
4. in devmode, it's done, in user mode, I'm not sure that, like pack in which mas and so on..
you can try it in dev mode first, if done, try on user mode.
Sry for my poooor description, hope you can understand it.
And what's more, the solution only works for global you know, all car's .veh use this gen will take this materialpath and use the material beside wccarbody will be override by materialoverride (I think so).

and what's more the texture resolution can be 2048x1024, so why not it can be 3072x2048 haha. Remapping UV is also not in my poor skill tree so I try to find that way.
But for your mod I think unless you create gen for each car have different WCEXTRA material mapping path and create different folder to put jsons, you can't do it perfectly(PBR differ from every car on WCEXTRAs)
 
Hi, to any one having errors while loading PBR, including:
1. Source map for render target XXXX.DDS CANNOT be a DXTn format
2. Error getting stats for texture XXXX.DDS Error loading texture XXXX for material XXXXX.
3. Error loading global material XXXXX

The cause of this BUG:
This error, IS NOT due to wrong MaterialPath setting, BUT due to wrong UTF-8 codepage used by material editor while saving json file from http://localhost:5397/materialeditor/index.html#/

HOW to fix this problem:
First download and install notepad++, then open your PBR XXXX.json file in notepad++, go to Main menu > Encoding , then select Encode in UTF-8-BOM and save your file, then check it in game, your PBR should load now.

PS: I have tested this in both firefox & chrome, and they have all saved XXXX.json file in UTF-8, which is causing loading bug. If 397 see this, please take a look at material editor for possible bug.
 
I haven't come across that one. But I do get this one with the Panoz when attempting to create a virtual ride. Could this be because I use separate .mas files for the Teams and Maps? The Teams.mas has the _basemat.json, and the maps.mas has the CC07_WCCARBODY.dds. Should these be merged into one?

try to put the needed files into one mas where the json at, I thinl that maybe enough
 
I just did a test, and moving everything into one file does seem to fix that issue. Looks like I'll have to do that from now on. It could get a bit messy with some mods. :confused:
 
What are the steps involved for applying the IBL/PBR shader to an object with the WCWING material? It seems from what I read you cannot use a custom region file to adjust the material like you can with WCCARBODY. I've been trying for hours to get this to work and it's not working

I have the material path in the gen file. Do I need to include another json? If so what should it be named WCWING.json? Does it need a reference in the veh file?
 
I spent the same amount of time on it as well, and at this time, it is not possible. For the DP01, I had some one map the WCWING texture to the WCCARBODY so it was all on one.
 
You can't have multiple region files that users can edit. You could use the ibl car body shader for multiple materials, but the regions would be fixed to whatever you set.
 
@Coutie Right, I understand that. What I'm asking is how do I apply a fixed IBL to a wing? Do I need a second basemat.json reference in the Veh file? Does the json need to be in a certain format? I apply the IBL/PBR shader in DevMod and I can get it to apply the IBL/PBR but it doesn't seem to apply it permanently, when I leave the session and come back, it's gone.

And I've gotten this error using the material editor trying to "save to devmod" before. But I have a material path in the gen file. Does the json need to be in with the general maps or does it have to be in the teams path?

I've just created a separate folder for materials, maybe you've encountered a bug, because the way you describe doing it is the same way I do it, and it works for me.
 
Yep I gave up on applying the IBL/PBR shader to the WCWING Chris. I combined the main and wing templates and have just one WCCARBODY material that controls both. I'm having someone help me with remapping the wings as well. What a PITA
 
Yeah I gave up as well but was lucky enough to find some one to be able to change it for the DP01. It would be great if this could be something that could be added in the future.
 
So a small update. In a conversation with @ChiefWiggum, he may have figured it out. I haven't done full testing on it, but I applied it to the camera texture on the DP01 and now the helmet.

I missed a 3DSimEd update that had the IBL shaders added. Here's Chief's post:
----------------------------------------------------------------------------------
I found out that the textures have same order as the json file

Direct X Shader = IBL Carbody Shader
Primary texture map
texturemap = basic Skin

Secondary texture map
channel 1
Diffuse map t2 = damage texture
channel 2
specular map = region texture
channel3
specular map = AO texture
channel 4
cube map = the json file have no texture, I used the carcube DX9 for the helmet
channel 5
bump map = damage bump texture
channel 6
rain drop map = 32x32flatn texture
channel 7
bump map = mettalicNoise texture

for me it works very good with the helmet, the helmet looks great
----------------------------------------------------------------------------------

Anybody know what the official take is on the Channel 4 and Channel 6 textures? It has good shading that matches the rest of the car, but I haven't gotten the region part to work either. I'm assuming because it might have something to do with not having a proper json.

Just putting this out there for the people that might know better than me :)
 
The new build 1.118 altered in a bad way the colors of our converted GTPC mod because I used old CARBODYPAINTWITHDAMAGE shader.

When switching to lastest L2IBLCARBODY I recover original colors so here are my solution to make a quick switch even if the mod are using multiple wcextra textures.

Pay attention that I'm not fully using PBR capacity as everycar use the same defined region with my method.

* Add a line MaterialPath=[directory_of_you_car]\teams in your .gen files
* Add some dds files in your teams directory (metallicNoise.dds / a damage.dds & damage_bump.dds / a Region.dds full black in my case / your AOmap.dds)
* No change in veh file as every car will use same region.dds
* Load your car on track in devmod and go to http://localhost:5397/materialeditor/index.html
* Find the material you want to change, WCCARBODY_000 for example, select L2IBLCARBODY shader in the list
* Fill the channel with your dds files like explained in several post of this topic
* Change the parameters of the regions (alpha/black/blue etc.) to your taste
* Save your .json file or download it

* At the end, you want this json file in your team directory. The json have to be named like the original material name. In my example, I've edited WCCARBODY material so my file is named WCCARBODY.json (for WCWING material the name is WCWING.json and so on)

* Open this file in notepad, find the first "Texture" line, fill it like this:
"Texture" : "wccarbody",
Check the other textures (some of them are already filled)
2nd "Texture": "name_of_your_damage_file",
3rd "Texture": "name_of_your_region_file",
4th "Texture": "name_of_your_AOmap_file",
5th "Texture": "CAR_CUBE_DX9",
6th "Texture": "name_of_your_damage_bump_file",
7th "Texture": "a rain normal file",
8th "Texture": "metallicNoise",
NB: I had to change "runtime" to true for damage & damage_bump to activate those textures

* You can do that for each material you want. It's also working with wcextra & wcwing (just place wcwing instead of wccarbody in your first texture line of your json)

***************************************

I've also tried to have one specific region file for each skin (with a MaterialOverride= in the veh file) but it worked only partialy. It was ok for the selected car but nok for AI cars (I don't know why but the AI region map was automaticly replaced by the defaultlivery.dds of the AI car giving strange results).
EDIT: Bug solved => in .veh the DefaultLivery line must have the extension .dds added to the name of the livery or you'll encounter a bug with AI region map.

I have a slight update. So looking at @Coutie 2018 Indycar (again S397 having some examples of car not encrypted helps modders), I figured out how the IBL works on the support textures. I'm not sure if I was doing something different before, but doing everything from the Material Editor worked.
http://localhost:5397/materialeditor/index.html#/

I followed along with the RIMS, using he same settings, same json material values, and I'm getting some strange artifacts. Any ideas?

For @Coutie, question for you. I was looking at the rims I noticed that you had a working normal/bump map for the rim (IC18_Rim_N.dds). Just wondering how you got that to work? I'm not seeing any references for that. I don't know if I am missing something. That would come in useful for my case as it would work for the body panel lines. I know it would come in useful for other cars

The normal map isn't being used, I just didn't take the file out.
