Unreal plugin fails to link on Linux due to missing gRPC symbols

Hi, just got a subscription to Convai and trying to get the plugin for Unreal working on Linux. I get to the last step having unreal compile it but the linking fails, after 30 files compiled with only some warnings, on missing gRPC related symbols. Earlier had it complained about a missing Source/ThirdParty/gRPC/lib/linux folder so I created an empty one.

Where do I find those libs for Linux? I guess those need to go into the Source/ThirdParty/gRPC/lib/linux folder

Hi <@797205920216121355>, thank you for reaching out, could you double check that you have downloaded the ThirdParty.zip file as mentioned in step number 2 and 3 in the following guide?

Ah, I unzipped it in the root of the plugin but I guess it should go into Source?

it needs to look something like this after you copy: Convai\Source\ThirdParty\gRPC

My test scene opened, can’t wait to go through the tutorials, thanks for the quick response and amazing tech! Pointer would be to adjust docs to make sure to say that ThirdParty needs to go into Source/
