T-pose and Uv

Hello, i have a character in standing position…i get the Uv correctly and imported in Keyshot ( here is all ok ) but… then i move my character using T-pose…, open the obj. file in keyshot and the Uv does not fit in the model.
Noob question…should re-unwrap my model again based in the new pose???.

Thanks in advance.
