character animation don't send video to NDI and OBS

Thanks for letting me know about your environment.
Do you have Preferences > Live Output > NDI output turned on?
If those states are fine, I don't know how to fix it.
Sorry about that.

Can you tell me more about your Mac environment?
(The NDI plug-in doesn't seem to work well on a Mac with an M1 chip.)
What version of OBS and CharacterAnimator do you have?
Do you have NewTek NDI® for Adobe® Creative Cloud® installed?

Thanks.

I had some troubles with NDI on my work laptop. There were issues with resolving the hostname, so it listened on the wrong up address (i cannot remember exact details). You could try using NDI monitor - can it see the ndi signal? if so, then it is an OBS problem. If not, if is on the Ch side in generating the NDI signal.

Siphon is a library allowing processes to talk only on the same machine - no network connections are supported (unlike NDI). So some of the potential NDI problems are avoided with Siphon. I could believe it's faster too, so it may be a better choice than NDI anyway. (Not sure, but from my reading previously it seemed "more direct".)

I translate Japanese into English with translation software

Did.

If you are a Mac user and want to project Adobe Character Animator to OBS, there is another way to do it besides NDI, using the Siphonclient.

It's simple because it doesn't use the Obs-ndi plugin.

Give it a try.

There's a lot of variables involved there. I used this tutorial to get ChAn working with OBS.

From there just make sure your selecting the NDI input in OBS.
