Special exporter needed?

[kungfooman]

Hey, this is interesting and I wonder how I can use this for my own models. Do you use Khronos Exporter for Blender or what kind of "export setup" do you use?

Some models have lots of clothes and I would like to export them separately, so they only waste network traffic and parsing time when they are actually used.

[shrekshao]

I used https://github.com/Kupoman/blendergltf. And after that quite some manual modifications.
There's a pipeline tool that will do some work. https://github.com/shrekshao/gltf-avatar-threejs/blob/master/tools/glavatar-pipeline.js

I'm far from finishing the auto export pipeline... Hopefully when I finished implementing one for real product I will be experienced enough to come back and add it.

wow. consider me a fan of what you are doing here. i am also really interessted in the steps you take to get a custom model from mixamo->blender into this system. i am trying to export a gltf with kupomans blendergltf and try to mimik your examples with the data i find there but as you can imagine its not very fruitful :)

do you have at least a rough explanation of the steps you take to get there or to add for example custom clothes?

@zen85 I basically followed this amazing article by Don Mccurdy https://www.donmccurdy.com/2017/11/06/creating-animated-gltf-characters-with-mixamo-and-blender/

Let me know if your have any additional questions

[zen85]

hey. thx for answering. nice - thats also my pipeline. donmccurdy did a great job here...
so when i do this i wanted to use your tool but it seems that it does not like me very much and throws me this:

pi@hassbian:/etc/gltf_conversion $ node glavatar-pipeline.js domi.gltf

does it have to run in a specific folder maybe? and what is it supposed to do anyway? :)

You need to npm install first

i did that... but now i get this:

i guess this has nothing to do with your work unfortunatly... do you still have a guess?

I newly cloned the repo and run npm install. Get some error message from registry.npmjs.org?

Doesn't look good...

[zen85]

so you mean the problem is indeed with npm? i tried multiple versions but without succes....

[shrekshao]

I actually have no idea what is going on here. Never encountered before. I'm not very familiar with npm either. Diving in would require some extra motivation at this point...

[zen85]

we are currently building an open-source alexa-like speech assistant with a lot of "tamagotchi" like options. now its time to make our models for the visual represantation customisable. from all the avatar-systems i saw yours most suits our needs. we already have a similar system in place but its kind of messy. how much extra-motivation are we talking about? :)

[shrekshao]

Sounds interesting. Do you have any demo/websites online?

not for public yet... but you got mail.

For the npm error, try

npm cache verify

or

npm cache clean --force

(I ran both and now everything is back to working. not sure which one actually did the job)
