NLAW Anti-tank RPG

Aga22

Hello people! long time no post. Inspired by the unfortunate conflict in Ukraine, i modeled the tiny giant killer that is helping the heroic word of the defenders, the NLAW. I built it in 3DS Max 21 and it's using 1 4k texture made in substance painter. It's the 1st time i built a model that encompasses everything in one texture and its been an education. The renders you see are in substance painter, with iray. I havent managed to get the same results in marmoset or unreal engine 4, even though i exported the textures specifically for that. (they look too shiny) Any suggestions?
