lightning storm 3D Model

scene of lightning striking a grassy field, I have provided 5 files first one is the blend file which is the native program used. I have also provided an obj, fbx, collada and an stl file. the scene including all models has a polycount of 936,688 blend file is ready to render preview images are all rendered using blender cycles using blender 2.79. note: Grass and sparks use particle systems and in order to improve compatibility in other 3d programs exported obj, stl, fbx, 3ds and collada files do not include particle systems or materials, only blend file includes particle system and materials. blend file has modifiers unapplyed so scene may be customized to your liking
