Hey, great video. Just wanted to add that there is a gltf output node that you can use for AO instead of having to create the output for it manually. It is a native addon in Blender called "Import-Export: GLTF 2.0 format" that has to be enabled in the Preferences --> Add-ons page. After you have enabled it, you need to click it to see its preferences and in there, there is a box you need to tick called "Shader Editor Add-ons". Now you can find it under Output nodes in the shader editor window.

It's work fine as a web showcase but we can't use open EXR file for using this as a full ACES open color in the game engine, maybe in a futur version with the USD Pixar format this stuff IS even lighter and contain all the material & texture in one file also volumetric data for smoke simulation.

Hmm this doesn't seem to work for me the same way. I've tried using 4.1 and 4.2.1 Stable. When I import I get an error saying .glb isn't recognised. I also get a red cross on the file and then when I try to open the models scene I get an error about needing an inherited scene. Whichever option I click on I'm unable to actually modify any settings. I'm not sure if I've hit a bug or if I'm breaking things somewhere?

Thanks. I'm just starting out with game development and these godot blender tutorials help a lot. Is it better to export game assets this way compared to using the .blend file directly. I'm worried using the new feature to import .blend files won't work properly or be as edible compared what was done in this video

@FinePointCGI Жыл бұрын

The blend direct feature uses the GLTF exporter. All it does is interface with blender and automatically runs the gltf exporter so all of the stuff in this video will transfer over.

Thanks very helpful, followed everything, except last step id like to tweak my material in engine. You seem to be able to change your material setting whereas mine are grayed out, thanks

@FinePointCGI 10 ай бұрын

When you want to edit that you need to break the import link by making it unique. so right click it and the make unique and it should become editable however that will break backwards compatability with the imported version so any changes will not carry over. It may be better to just on import export the material to a file. You can do this by double clicking on the asset in the file browser and then upper left under actions select export material (i think im away from my keyboard at this moment)

Hi! When I import .glbs it always dumps my textures next to the .glb, even though I used the same settings as you. Where do your (generated)textures go? How can I have the same behaviour?

@JayFolipurba 6 ай бұрын

No I did like this video and I will come back to it. Although I also just saw a video that explained that you can import straight up blender files to godot and I'm wondering how much that changes things/ if that makes this completely obsolete, or if this still has an application

@FinePointCGI 6 ай бұрын

It does not change anything .blend files get converted to gltf by Godot on import thats how it works!

@dx9xd Жыл бұрын

Is there an upside to this method in Godot over just importing the .blend file like they added in G4? I really like not having to re-export from blender each time a change is made

@FinePointCGI Жыл бұрын

This is the exact same method if you want to just import your blend file using Godot you need to set up your materials in the same way. Under the hood all it does is exported out from blender to GLTF and import it into Godot. It just does it automatically. So the setup is still the same all of the stuff in this tutorial is still applicable. Some other advantages is if you need to share textures between multiple assets and things like that then exporting it out as GLTF is better.

But this isn't working for me (I'm using complex shaders made in Blender). I think glTF can export basic shaders but can't handle complex ones. I'm currently recreating the shader in Godot using the visual shader editor. Is there a way to export complex materials too? (Probably not, since Godot uses a different shader program than Blender, but let me know if there's a method)

@akanahketo5823 9 ай бұрын

Yes, glb/gltf is the best option for import blend-objekt to godot. .FBX doesn´t work and .obj don´t show all textures.

How do you export in such a way that you can use the model as a collision shape also?

@giantfrogstudios839 Жыл бұрын

Yes I would like to know how to use the models as collisions shapes too please

@FinePointCGI Жыл бұрын

Ill be doing a quick tip on this (under one min video on this) but the upshot is add -colonly to the name of the collision mesh and it will import in as a collision mesh if you use -col it will DUPLICATE the mesh and use that as collision.

So let's say I wanted to make a map in blender, how would I make it to where all my maps use the same texture instead of having to store a separate copy of the texture in every maps file so I'm not wasting tons of space unnecessarily (oh yeah and the maps are exported as gltf obviously)

@nullvoid3545 Жыл бұрын

If exported as one file, I'm pretty sure that shared textures will not be duplicated in the file. That being said, if your exporting multiple glTF files I don't think that blender will be able to reference the texture in another glTF file. glTF itself has ways of referencing external textures and materials but to get Blender to do this you may need to enable exporting your materials as linked .mtl files in Blenders glTF export settings. Another solution is to use the "use placeholder materials" export setting in Blender and then set the materials manually in Godot. They should stay linked when reexporting the glTF as long as you keep the same material name between edits. This can be A pain to do manually if your exporting A lot of meshes, but If your making fancy materials with shaders in Godot then placeholders may be right for you.

@FinePointCGI Жыл бұрын

This is correct if you export them out all together it will reference the same texture however if you are exporting them separately what you could do is export them out as glTF + bin + texture and it "should" reference the same texture though I'll do some testing and verify..

@jlewwis1995 Жыл бұрын

@@FinePointCGI alright, what I was planning on doing is having a set of folders with all my textures in it as pngs + shaders + .tres's and in blender just having the models use those external pngs while still being able to use some of the features of gltf like vertex colors and being able to divide the mesh up into several submeshes that get imported as separate objects

@FinePointCGI Жыл бұрын

@@jlewwis1995 So after some testing what I said above will work you can export with gltf + textures and it will make proper shared references. Something to note though, if your textures have the same name such as lampalbedo.png and lampalbedo.png it will be overwritten and they will use the same texture EVEN IF ITS DIFFERENT IN BLENDER so keep that in mind. I would suggest using the blender batch exporter since that can really help streamline your export process!

Once i place my model in scene, I then press open in editor adjacent to it, and it says since it auto imported it can't be modified, to make changes a new inherited scene can be created. If I do that then I can't edit the material. If I press open anyway then I can edit the material. How do I extract material? Thanks sorry new to godot 4 days ago
