plattar / gltf-exporter Goto Github PK

Hello! This might be a bit of a longshot, but I've noticed that exporting some varieties of custom materials results in material data being lost. For example, exporting an object that looks like this

results in

I imagine there are limitations to what can be supported by the exporter tool, but I imagine that custom material types such as these are relatively common in Unity projects and that custom materials need to be in some sort of unified format for Unity to recognize and use them.... hoping that there's an implementable solution for this asset that could be applied in the future.

I should mention that regular material assets export just fine.

How do I export 3D models from Unity, including lightmaps? Is it possible to export baked lighting?

I'm looking for a tool that allows you to burn lighting from a 3D scene and save it in glTF format - unfortunately 3DS MAX (with V-Ray) or Unity can calculate great lighting but do not have a glTF exporter ...

Hi,

First of all, thank you for the great plugin.
We were wondering if there is any chances you will implement URP support?

Kind Regards,
Thijs

I export a gameObject with material animation,but didn't with it?what kind of material can i export or how to resulve it?

Trying to figure out what I am doing wrong.. I imported PlattarExporter by double clicking on the unity package downloaded from releases section. I see PlattarExporter in the Assets folder now. But no toolbar as suggest in the screenshot.

I am using Unity 2020.3.27f1 Personal

Am I importing the package incorrectly?

I don't know if im doing something bad or if is the plugin but when i try do export the GLTF this error appears. i'm trying to export in runtime.

Hi,
Thank you for this fantastic exporter for Unity
I would know if is possible to export also "Audio Sorce" and not only Animations
If not, is it in develop?
Thanks again :)

I installed the asset over the unitypackage, the new toolbar item is missing and i get two errors:

Assets\PlattarExporter\UnityGLTF\Scripts\GLTFUtils.cs(191,3): error CS0433: The type 'ZipFile' exists in both 'Ionic.Zip.Unity, Version=1.9.1.9000, Culture=neutral, PublicKeyToken=null' and 'Ionic.Zip, Version=1.9.1.8, Culture=neutral, PublicKeyToken=edbe51ad942a3f5c'

I'm on windows 10 and my Unity version is 2020.2.2f1

I am selecting a proper game object in Unity for export. The GLTF zip only contains the normal map texture along with the mesh and .bin file. The normal map texture appears as a pink image. Not as a usual purple normal map. Also, I expected my baked game object to include the baked look of the asset. I mean, its in Unity, I bake my scene, and select a game object to export as GLTF and expected to see the lightmap in the GLTF version. Is this supported?

Im trying to use GLTF objects from Unity for Babylon.js scenes.

Can I export to gltf a gameobject that is created at runtime? Can I have a reference to said model in memory, and not have to save it?

Hey there, truly great plugin. Probably the only actually working one I could ever find and I'm using this with three.js :)
Strange thing is, I see normal maps are in somewhat red-ish color. Is this expected? I normally would expect to see the regular purple palette so I thought I should ask here.

Thanks a lot in advance. Attached is the exported folder.

Skinned MeshRenderer not support

Was surprised that this gltf exporter for unity does not support iOS.

This other one seems to work

https://github.com/ousttrue/UniGLTF

Using Unity v2019.1.5.f1. After importing the package, I get the attached warning in the console and the Plattar Exporter menu option doesn't show up. Using Win10 build 1803 (17134.829)

Sadly I'm very much a novice, so I'm not sure how to fix the script.

Thanks in advance!

As per title.
Now if I export an object, it creates 3+ files: the GLTF file, the BIN file and N# files per textures.
But what if I want a single file embedding all of that?
Is this possible by changing the script? Would be nice to have an option to choose between "GLTF separated" and "GLTF embedded".
Thanks a lot!

Hello, I'm encountering a problem when exporting unity materials to GLTF.
