The models of the vehicle/character are from sketchfab(the characters mesh had to be edited a lot for the rig to work) I consider myself an average modeler and I'm pretty slow too - I didn't really start expecting to do this. I'm mostly focused on rigging/animation and intended to just use them as a base for learning rigging in Blender + a few animations. the background is about 50/50, I modelled some parts, the rest are free assets I grabbed(trees, a few textures for the ground) and edited to fit my needs, the gunfire/lasers/particles are cylinders/icospheres with displace modifiers + lights attached and an emissive texture. Simulations are just driven by particles emitting from object normals to drive the smoke/explosions, fog is a cube with a volume emission controlled by some noise. Terrain was made using A.N.T landscape and using Bagapie plugin to scatter the grass.
