Residual Modelling and Generating Scenarios for variables

newbie here with a trivial question. i am trying to create scenarios on a set of macro variables. i started with creating a bayesian VAR model on insample data and created some forecasts. then took the residuals from the model and used copula to find the joint distribution from the marginal distribution of the residuals of the variables. I found out the ranks of error of variables and Fit a t copula. Then I simulated the errors from the built copula.

now that i have simulated errors, if i wanted to create scenarios based on these simulation, how should I go about it? Should I just add the simulated errors to the mean of the forecasts? How do I get simulated paths for each variable?
