The paintjob is not displaying properly in game

Post by Mmeister »

Hi,

I have a problem with this particular model of Volvo FH 2012 where the paintjob in game does not work properly. It seems misplaced but the mapping of surfaces seems to be in correct place. I have no luck getting it work.
-I've tried change ''clamp'' to ''wrap'' on both DETAIL1 and SPECMAP - set by default UV#1
-I've tried Bumpmap on UV#2 (default UV#1)

Any help would be appreciated. Thank you.

Here are screenshots of my settings.

bump could be using uv#3 or even uv#4.

Just tried both options. Makes no change :/

To be more precise. When I change to UV#3, I can see change in model - then I copy from UV#1 and its fixed in modeler. But the game still wont read it properly...

Any other options I may be looking at?

Separate to UV#3

Copying coordinates from UV#1 - looks correct, but in game paintjob does not work.

in most of cases, you should not copy uv coordinates on a model (as you are likely to loose uv mapping on a channel, that you are unaware the use of).

So, if some texture looks properly on a model with UV#1, then you should assign UV#1 for this texture in options page. E.g. BUMPMAP "Use mapping : Manual UV#1" or something like this.

there were not screenshots on what is get messed in game - is it bump messed? or paint/skin mapping is wrong?

It looks like this. The part around lights should be red/white stripes and the rear big cover should be different as well.

This is how its supposed to look.

if the skin mapping is wrong, then change DETAIL2 texture slot settings to "Manual UV#3"

The paint/skin mapping is wrong.

I tried with DETAIL2 change to UV#3 but nothing changed. DETAIL2 has no texture, does it matter somehow?
Also i left BUMP now at UV#1, should i set that to UV#3 as well?

what is your SCSSoftPrism3D.zmf file version as shown in Settings->Plugins->Manager?
I remind this issue was fixed in recent updates already.

does changing BUMP to UV#3 made this work? actually it should not.

Yeah BUMP to UV#3 + DETAIL2 to UV#3 works.

Only DETAIL2 to UV#3 does not work. Tried again to be sure.

This Volvo FH 2012 model seems built different from other trucks I've edited so far.

After BUMP set to UV#3 it looks wrong in modeler but ok in game?

As original at least in configurator, will try drive truck.

This is the version:

is this an original game model? what is model file name/location? I'll take a look what's so special with it.

It is original SCS model. 8x4 chassis I've extended to 10x.

The r_fender_top & r_fender folder under accessories I've found the paint version of fender has a problem with at least 2 skins: Golden edge(barely noticeable inside fender) and Special Transport(on image below).

DETAIL2 set from UV#1 to UV#3 crashes the game before loading into main menu. If also BUMP is set to UV#3 then game loads but then mapping is wrong for all skins.

Hi Oleg, any solutions here?

If I did something incredibly stupid to get this result I don't mind being told so. I'm still learning the software and game modding.

what are correct channels for every texture on this model? set them in ZModeler to see the effect. Given the correct setup, I could be able to specify what steps should be done to export it properly.

Note, the game can assign different UV channels for different texture slots of the same material on one object and another. ZModeler can't do this. For example, one part can use UV#1 for main texture and bump-map, and another part can use UV#3 for bump-map on the same material. Game assigns UV channels on per-object level. In ZModeler UV channels are assigned on material itself.
Thus, changing material settings could "fix" one object and "corrupt" another object on the same material.
