Correct Workflow for importing Meshes in Godot 3.0?

Conducto

Hello :-)

I am having trouble to figure out the "correct" workflow to import meshes into Godot from Blender (v2.79). For my tests I try to import this tree mesh which i found on OpenGameArt.org ( https://opengameart.org/content/low-poly-trees-stumps-branches )

Currently there are three ways - but none of them working properly: 1. Export as Collada using "Better Collada Exporter": Exporting the mesh and unticking the option "Copy Images" so that I have to export material textures manually into the subfolder "images" and assign them to the materials in godot by hand. Problem here is that transparency of the leafs is not rendered correctly (actually i think this is a lot of effort considering you'll have to go through all this steps for each mesh you want to use in a game) 2. Export as Collada using "Better Collada Exporter (2): Exporting the mesh and activating the option "Copy Images": This crashes the exporter completely and no mesh file nor images are written to disk. 3. Export as GLTF 2.0: Since this format is a new feature of Godot 3 and is promoted by the developers in this blog article ( https://godotengine.org/article/we-should-all-use-gltf-20-export-3d-assets-game-engines ) I thought it might be worth a try to test it with the GLTF-Plugin for Blender by the Khronos Group which I found here: https://github.com/KhronosGroup/glTF-Blender-Exporter The exporter works but when i import the mesh in Godot I only get the stem of the tree, the leafs are missing.

So I've spent lots of time the last few days to figure out how the workflow would work but each option doesn't achieve the 100% and has major flaws... maybe I am getting it wrong or is it just too early to expect a fully functional import-export workflow between godot and blender?

Any clues or ideas are appreciated. If you want to try it out yourself, you can find the blender file on OpenGameArt (use the link above). BTW: I tried other meshes as well - but none ex- and imported correctly...

Hi there,

Your tree is made of two objects, select both in Blender and export with "Better Collada" with the same settings as the picture below. Godot will import it as a model and two white materials.

You'll have to create two materials to get textures on the tree like below.

One material is transparent, check "transparent" Flag on , and choose Roughness 0.8 for example.

I tried GLFT 2.0 and Godot crashes. Notice GLFT source update was two months ago.

Now don't forget about the import panel in godot. Plenty of useful options in there too. You have to highlight the importable file in godots filesystem browser for the options to come up in the import panel though.

Hi MagicLord,

thank you so much. It works! :-) So I'll use the better collada exporter and will hope that GLTF will continue to evolve :-)

Also make sure the normalmap is oriented correctly for godot. The difference between blender and godot should be the red channel.

@Megalomaniak Yes, i noticed that Godot's import offers a lot of options too. So as a beginner you have plenty of combinations of all those options on the blender side (or other tools) and Godot. That makes it pretty hard to figure out the basic workflows when you are not that deep into that "graphics low level stuff" and just a hobbyist with a few prototyping ideas in your head...:-) But Its good to know that there is such a strong and friendly community you can rely on! So again: Thank you so much! :-)

Well, godots import settings are mostly for the import scene setup like do we need to setup an animation node for this, yes/no? Do you want to import the model as a scene or a mesh? Where to link/store imported materials etc.
