Understood, I updated the comment to include the “robust” error code. I also very literally gave a recounting of how to repro the error. Also, looking for a validation that the error is on the Epic side of things (or not).
Might be due to the ThirdPerson template including HMD inputs but maybe bare C++ project doesn’t include those.
The TP template does have blueprint code for tracking HMD, so that’s my guess.
Your constructor has a Constructor Helper that hard codes the character. It must be in a different directory in your project browser which is why it’s failing to find it. Just right click over ThirdPersonCharacter_C in the content browser and Copy Reference. Then replace it with the directory you mentioned.
