Bonjour JLH,
Yes, there will be some battlefield smokes from the muskets and canons... and very good looking smokes too.. but, I do not think that the muskets and canons will create the big cloud of 'smoke-fog' on the battlefield as you expect..
Do not despair.. there will be real 'weather-fog' that makes the visibility bad.. but not so much the 'smoke-fog'... of course, I do not make the game engine... so, I defer to JMM as the final authority on 'smoke-fog'.. hahahahahahahahahahaha
Cordialement, Duc d'Earl
