We are the developers of the Modern Combat mod for Relic's Company of Heroes.
This is a video showcasting exactly all the steps I took in creating the Stryker and its variants for the Company of Heroes: Modern Combat mod. Please note, I spend a lot of time fiddling with the M240b hatch animation and the recoil setup. I highly suggest you skip these parts and see what I do in the end, as I waste a lot of time doing an incorrect setup.
I hope you can learn some new things about creating a model. I would highly suggest that you create a proper occlusion map, as seen in my Multi Tool tutorial:
I would like to post a way to coding the model in Mod Studio, although I am not well rehearsed in this coding, so I will leave it out.
Main things to know about custom model integration is to create a .abp
Copy over states from OE to the anim_bag of the weapon.rgd
Make sure to have the fx_tracers and fx_target for machine_gun weapons to be the same as your OE setup
In ebps files create actions in the upgrade_action in order to apply states - useful for variants of models
For projectiles make sure to place the correct marker for the entry point of the projectile mesh
I believe that is all,
Thank you very much for watching,
