If you click on a file to import and the "Import" button becomes dimmed, then the model file is locked. This is usually the case with models/mods downloaded from the web. ZModeler should still be able to import vanilla game models.

If you import the file and see something in a hierarchy view, then you should probably toggle on "L0" button on Structure panel above, so you can see the highest LOD (Level of Detail of the geometry mesh).

I import and I don't even see a car, I click to import on the car to bring up the screen and load the car and it doesn't even do that

Well thank you for your quick response!
Yeah i will try that out. I'm just buffled cause i used the meta files of the new og police gauntlet and just changed the name of the model /texture file in Gta5.
I will look into this.

But thank you again!

There is no a kind of a "shader support" by ZModeler - it either reads model with this shader or not. The shader configuration was taken from original model and I expect the exported material to have the very same setup as original model.

I advise to import/export original model (may be with tiny changes like moved vertices to create visible spikes) and test siren track shader in action on modified model. It is possible the model requires some "uv animation" setup in metadata file as I think the UV animation parameters are kinda global for entire model (with no respect on what shader is currently in action). Given that, there might be an option/flag to accelerate animation speed with increase of rpm or not.

Give it a try with original model first.

Actually i'm not sure if this bug is related to Zmodeler3 3.3.0 but i was trying to get the new police-lights onto an older car and the "vehicle_track_siren" Shader is kind of bugged after exporting. It uses the "track" shader from the older cars like the inner lights of the patriot limo or normal "engine-belts" like when accelerating the anim will getting faster aswell (i hope you know what i mean lol)

Well this is a whole new "track" shader Rockstar games made for these police lights. And i'm not quite sure if this shader is fully supported by your programm right now (Just like i said its my assumption, not quite based on any facts. Please proof me wrong here haha)

If anyone has/had the same problem and found a fix already please let me know as i'm struggling to get those track anims working (the normal sirens work like they should, only the "vehicle_track_siren" sirens are not working like they should.

Well anyways, great tool and thank you for a reply.

what is your video hardware? Do you get any errors when loading/saving .z3d file in 3.3.0?

May you send me any of your 3.2.1 .z3d file that does this? There were reports of this issue but I was unable to reproduce it yet.

I keep having an issue that is very annoying. When i open a z3d from version 3.2 and save on 3.3, when i open it again, ALL the textures are gone and i have to reimport them manually. Using the latest update, could there be a fix for this please

provide more details, perfectly include screenshots, so I can see what is wrong.
also, what does "i cant even open a save only through autosave" means? what happens when you pick File\Save or File\Open?

Well, I did everything I could ... Video card settings, modes, screen, its functions. But I really noticed that when the driver was removed, Blender could not be started, there was no OpenGL 3.3. Well, since the Zmodeler does not use third-party programs, I think this does not apply to him.

:lol: :cry:

In general, ZModeler does not require anything to be installed, it does not use any additional libraries. ZModeler requires DirectX11 to be installed on the system. If you do not see any error on startup, then everything is ok for ZModeler to run.

May be some per-application settings in ATI control panel can help?

ZModeler uses backward data transfer from GPU to CPU to draw viewports, as it applies some overlays on rendered viewport data before showing it. So, there are some aspects that can affect this scenario:
1. GPU video memory not providing data back to CPU for some reason.
2. Your display setup has some adjustments that make it impossible to show rendered data in vewiport for some reason. For example, non-32 bit color depth profile selected, sRGB mode, may be an enabled HDR...

Here's are mine display settings in windows:

I have an ATI MOBILITY RADEON HD 5730 ( :D ) The old version works fine and all other games and programs, but this version does not. Maybe something else to install for full work? What else does the program need? I just sat, installed all the versions of the drivers that are generally available for this video card, all to no avail ...

Re: ZModeler 3.3.0 release notes

There is no solution at the moment. I have nVidia 3070 on my dev PC, and nVidia 1060 on my laptop device. Laptop has also Intel(r)Graphics on-CPU device too. ZModeler runs fine on any of these devices, so I can not reproduce the black-views issue.

May be you can try different video drives (e.g. start from removing video driver at all), then let windows install driver automatically and finally, download the latest driver from your video vendor's website.

Приветствую! У меня такая проблема, чёрные экраны и все, ничего в них не сделаешь, я так полагаю, ноутбук можно выкидывать или можно что-то придумать?

Re: ZModeler 3.3.0 release notes

pass it through any other image conversion utility to fix. The texture data could be messed up already and ZModeler can't load such a texture. For example, make an export to .yft file and put this texture there as an embedded texture. Then extract it from .yft file with OpenIV.

The texture is a set of texture data objects (mips) and DDS heading that specifies how to read the data. In ZModeler 3.2 some texture heading are ignored and only the most significant heading data values are used to read texture data. That is why it can still show and use this texture. Upon saving, bad .dds heading data makes the texture unloadable buy most of DDS loaders. When you put this texture as embedded in .yft, the texture data (unchanged) is equipped with yft embedded texture heading, and OpenIV will be able to reconstruct correct DDS heading for this data to save a proper DDS image.

I can not make any changes to ZModeler 3.2.x product anymore, so I can not fix this issue with ZModeler 3.2. textures.

Also, keep in mind that ZModeler 3.2. uses DX9 engine and does not support some of texture formats like ATI1, ATI2 (BC5 normal map), so texture data in ZModeler 3.2. could be incompatible with DDS texture heading (e.g. ATI2 texture loaded in ZModeler 3.2. sill has ATI2 DDS heading, but the actual texture is BC3-converted DXT5 texture). This can cause problems too.

no ZModeler doesnt load normal maps that was saved from 3.2

You can save texture ZModeler 3.3.0 - these textures will be loadable by other tools. In case of problematic textures (BC5), save them from ZModeler 3.2.1, and load again into ZModeler 3.3.0 (it will load these DDS files even if other texture tools reject them).

yes i figured that out but too bad the textures thats saved from 3.2.1 doesn't work in any paint program they ruined

Re: ZModeler 3.3.0 release notes

ZModeler 3.2.1 uses DirectX9 engine and it has no native support of ATI2 (BC5U) textures, so these textures are converted to another texture format on load. Even though ZModeler shows you texture type ATI2, it is not actually ATI2 texture data in the engine. On export (where texture data is actually needed to save texture data) ZModeler performs BC5 packing again, so this is not actually visible for the user that ZModeler performs conversions.

ZModeler 3.3.0 uses DirectX11 engine that supports ATI1 and ATI2 textures natively, so no conversion is performed and BC5 texture can actually be used. However, your saved .z3d files contain different texture data (but still claims "this is ATI2 format"). I advise you to use "Replace" button in textures browser and reload problematic textures from your hard drive. Once they are loaded by ZModeler 3.3.0, they will appear fine and you can use your projects further.

Here's an example how this native texture look alike after loading from the hard drive:

Your screenshot is very small, I can't see anything. Upload full scale screenshot or describe in detail what exactly is wrong.

Also, there was an update addressing textures (mostly affect non-compressed ARGB, BGRA textures) just recently (

Do not put ZModeler on your desktop, "My documents" or "Downloads" folder. Make sure to run ZModeler as Administrator. ZModeler starts several processes and uses inter-process communication. Running application in a regular way or from any user-account protected folder might block processes to start properly.
