ZModeler forum

@Oleg, it's not addon wheels

my test model (buffalo2) after import/export with the latest version is absolutely ok.

recent changes in filter involve axes export update on COL objects that are a group-objects. if you don't have groups on your COLs, your export should be unaffected by recent changes.

If I wanted to have a material with little reflections and shine (similar to this), what would be the best specmap to use?

@Oleg, sorry, my fault, i exported it with skeletal off...
i just I didnt notice it

use dark red texture in specmap.

i have a problem Oleg, with my model when i import it into zmod the model bugs out or something and i get those weird lines and they stay there when put into game but the origional model is absolutely fine but it didnt get imported to zmod... hopefully you can help.




King regards, Bulldog designs

this looks like a vertices limit hit on object(s). each object can not exceed 64K of vertices. If you import your model from a different format, you should chop it to smaller objects, so limit is not hit. Inside ZModeler, you can not use Modify\Attach on objects, as a result merged object could hit the limit again: instead, use "Group" button. GTA exporter can export objects that are groups, so limit is not a problem on export (unless object is not messed already).

Sorry, what do you mean buy that i got a little confused?

load your model into zmodeler in parts: object chassis (one file), then load object bonnet,bumper, roof (another file) then load doors and interior (third file). and so on.

in ZModeler arrange objects to correct gta parts; if you use Modify\Attach tool and get messed polygons (like on your screenshots), then use "Group" button on "Structure" panel for these objects instead of Attach tool.

How do you load separate parts into zmod like your explaining?

Oleg, every time I reload my .z3d file after saving, the mapping for UV #2 doesn't save, which leaves me to redo all of the mapping again. What's the problem?

Set it in Properties->Vehicles->Format->UV Channels.

@Oleg
Could you take a look at the lowriders suspension e.g. faction2? Their polygons are missing in few places.

Path is: update\x64\dlcpacks\mplowrider\dlc.rpf\x64\levels\gta5\vehicles\lowvehicles.rpf\faction2_hi.yft

Springs texture are animated somehow?

In order to make or edit this model the way R* did it, you should load it in non-sliced mode. Rear suspension vertices are mostly assigned to "transmission_r" bone, when I move it down, most of vertices move too, but not as a "separate part". You can see springs are stretching, as opposite vertices of springs are assigned to "chassis" bone influence. This allows simulation of stretching parts (like springs) at no cost for the game engine:
If you load this model with no "Slice to parts" option, you will see it yourself too.

In order to revert to this, or make your own mod the same way, you should:

1. attach all related polygons to rear suspension part first;
2. export your model (unlocked)
3. import your model with no "Slice to parts" option;
4. set "Chassis" as current bone on ".skel" object;
5. switch ".mesh" object to vertices level; hide all unnecessary elements using Select\Element or Select\Separated + Hide tool; make sure only suspension is shown (and unnecessary parts of chassis can be hidden too)
6. use Rigging\Influence\Paint tool on tips of meshes to "attach" associated vertices to "chassis" bone;
7. save as .z3d; export; test in game; if not satisfied, undo and redo #6-#7.

if your spring model is 3D spring, you can use soft brush paint feature, allowing zero-to-full gradient paint of influence on the spring object: lower vertices will have 100% suspension influence; upper vertices will have 100% chassis influence; mid will fade respectively (gradient from deep red to deep blue and fade to transparent).

On the image below, neon_b bone influence was soft-painted to the rear of the vehicle. it was done with max size of brush, 0 hardness and single click&drag paint operation in Left view (if you paint in perspective view, toggle off "Solid" mode)
And that's how mesh is stretched when I move associated bone backward:
The game does the same with suspension. Just make sure to set your model properly and assign vertices influence to correct bones in non-sliced mode. sliced mode will always produce "rigid" components for vehicle skeleton/hierarchy.


P.S. [un-relevant to your case] if you unbind skeleton from mesh after such a soft-skin modification like on the latest image, the affected mesh will accept transformation in latest "pose". This could be used to adapt ped models to gta skeletons when they don't match perfectly in rest pose.

Front and Rear doors reflections different, how to fix this? I try reuvmap#1 and reuvmap#2 but not fix

does Surface\Normals\Calculate produce good result in ZModeler on these two objects?

Bad view

looks like a bad import from 3dsmax. when you import 3dsmax models (via OBJ or DAE) make sure to toggle on "Optimize vertices". now you can use Modify\Weld tool on vertices level: select all verts, expand options of Weld tool, enable Multiple Target option; click on any of selected vertices, specify options: distance = 0; uv tolerance = 0.1, normals angle = 40. then use Normals\calculate tool again.

Hi Oleg,

I'm actually facing a problem with the attachments of the weapons. When I replace a weapon, I need to keep the dummies for the flashlight, scope, silencer... at their exact original position (position which I got when importing the .ydr of the original weapon). If I move those dummies to have the attachments in the appropriate position for this new weapon, in game the result is that the attachment position is good, but when I shoot or reload, they goes back to their original position.

Step to reproduce : Import a weapon, move the silencer dummy, export and test.

The workarround is to export new attachments for each weapon, but I'm pretty sure there is a way to do this properly with Z3D. Maybe a hidden value somewhere that I missed.

If you have any idea ?

Thanks

this is a known issue of animation playback suppressing bones/objects setup in your model hierarchy.

you can create a "position adjuster dummy" for the part you need to refine position. For example, lets say a shell-ejection part "S" needs to be repositioned, and it is mounted on a bone named Gun_MainBone. You create a bone named my_pos_adjust01 and put it into Gun_MainBone; then drag&drop part "S" into "my_pos_adjust01" in hierarchy; then use Alt+Click on [v] icon of my_pos_adjust01 to get it selected in viewport. toggle off "Auto" selection mode in the bottom of ZModeler window; then use modify\move (ensure "Affect children is toggled on) and move object in viewport to get "S" position at desired location. note, the "my_pos_adjust01" will actually move, and "S" being the child of it will get moved too. then export and test in game.

P.S. the problem you describe also relates to earlier versions of the filter, make sure you run the latest copy of ZModeler.

Your solution has not worked. It has reproduced the same problem but with the attachment at another position when reloading or shooting.

However, it has put me in the right way to solve the problem :

If I need to move, let's say, the silencer :

-Keep the WAPSupp dummy bone in the original position
-Copy this dummy bone and name it WAPSupp_2, and put it in the hierarchy of WAPSupp.
-WAPSupp_2 is this bone which will determinate the position of the attachment. So we can move it freely

Final step is to go in weapon.meta and change
with
This method is also used by Rockstar for some add-on weapons.

Thanks Oleg for your help.

All vehicle compound models has Tangents option enabled?

to whom is this question for?

To everyone, to you too.

Tangents are required on objects that have material with bump shader (any shader utilizing BUMPMAP slot). availability of Tangents on objects that don't use BUMPMAP is insignificant, as exporter will write tangents data when material requires it. So, you can enable it on all objects to be safe.

i have an issue, my model has been uv mapped and textured and shows in zmod 2 and 3 but doesnt want to work in game and is starting to get on my nerves because it wants to use the environments textures and my textures wont work on those parts :/
