I see the material sample sphere in black color, so this is something in material properties that makes it appear black. open material properties and examine what exactly is there. (double-click on material or use options button on the left of "quick configuration" button you've used)

Can't be of much help on this subject. I have tested modified .ycd files on original game's vehicle model. This model has roof animation configured natively, so I did nothing to configure or enable/disable animation playback (only tested what bones will be animated inside .ycd file and what exactly ...

Unfortunately, I have no idea how the game controls animation playback scenario - whether it will be played backward or not. This is not something inside the animation file itself, this is how the game's animation code plays the animation file.

Hello.
The model file is locked or was not read by ZModeler due to unexpected model data layout in a file. ZModeler should still be able to load original game models.

do you mean, the animation via .ycd file that works with your mod (when model is set to type "vehicle") and stops working when you set type "bike" ?

You can't assign what UV channel the texture slot will use in game - this is hard-coded in game's shaders. You can make changes in ZModeler but this will not take effect in game. In your case, you should use "vehicle_paint4" shader adaptation instead. This is generally the same as paint3 w...

what do you mean by "animate parts"? The game has a build-in mechanics for some parts on how they are supposed to behave in game. For example, front forks can slide one along another, the rear fork is on rotational joint and have some rotation on pivoting axis.

it doesn't really matter - the video shows that game accepts the rig (small skeleton) that fits the geometry (small ped) and acts properly. your geometry model should be rigged to the rig that fits its needs. if you need smaller lower part and bigger upper part - you can adjust the skeleton this way...

if you adjust skeleton's bones the animation will still play the pre-defined rotations, so in-game animation might not match perfectly your model. Yet the rigging might be better, but the overall appearance might suffer. The rig is stored in a .yft file separately from the geometry models (.ydd file...

your model geometry has excessive detail level for the game. you should optimize geometry significantly before using this model in game. Yet the game engine can handle it, but some PCs can suffer a performance drawback when several such a vehicles appear in a frame.

Hello.
Fixed, get an update.

P.S. Your ZModeler version on screenshot looks very old.

this is an object with vertices count exceeding 64K limit. Currently ZModeler filter version should not give such a model on import, it will create a group of objects (each utilizing less than 64K vertices) combined into a single object as "Group object". You have cropped the image, so I d...

Текстуры на GTA модель скорее всего подгружаются из архивов .ytd. Необходимо выгрузить текстуры из архивов в .dds файлы и поместить эти файлы в ту же папку, что и файл с моделью.

this is certainly no good. you have two versions of plugin and you probably can't control which one is used to export. I advise to get rid of the .alt version.

No. what is the version of your SCS filter? It is shown in Settings->Plugins->Manager window.

light masking texture should be in MASK slot. It is not drawn in viewports, it is used to mask only. And again I see "texture" blocks preceding the parameters block in generated .mat file - the most recent version of plugin does not use such a layout. You certainly use an old version of pl...

This is generally all you need to know about UV mapping: https://www.youtube.com/watch?v=6l3G55ufr2c the scratch-made model should probably be mapped in side / front / back / top viewports iteratively. Some [selected] polygons should be mapped from left view (Generate New + From Viewport XY mode), o...

This is not something that is activated or disabled. The filter has a pre-defined template on how .mat files are created. If you have the latest filter version, it should follow this pattern. What is your filter version as shown in Settings\Plugins\Manager?

Формат .obj это скорее наихудший выбор для переноса модели из ZModeler в Blender. У него отдельные файлы с материалом и разные программы по-разному их читают, поскльку формат нестандартизирован и допускает различные толкования. Также, он не сохраняет цвет вершинок и второй канал мэппинга. Рекомендую...

make sure your bus has chassis object's local axes at 0,0,0 point. You should not position your bus to match the door location on original bus, instead, place it alike to original (centered on Z). If you misplace the bus relative to 0,0,0 point, there might be an issue with physics, steering, bus le...

if it's shaking when model is standing with no movement, then this is the wind effect.
if it shakes when player is walking/running, then the rigging is incorrect, you should fix the rig by copying it from the associated shirt object (the uppr_*** component the vest will be used with.

The exporter should either write specific texture parameters or a line of code "sampler : default". Either of these, it can't leave "texture : ...." on its own with no other data.
The latest filter version is 3.3.0.512

Is this an issue with just one material / scene? or any other scene/material get the same .mat export layout pattern?

no ideas on this. is there an original game's truck upgrade that does this (middle headlights)? if there are, make a tests on these headlights. 1. import/export with no changes and test in game 2. import/change mask texture to yours/ refine UV#2 mapping/test in game 3. import/replace geometry with y...

the texture settings options like mip_filter, u_address, v_address etc are available in the latest filter version. Are you sure you use the latest filter version? because it have to add at least "sampler : default" row on every texture slot. This is an example of zmodeler-generated .mat fi...
