This new mod version contains custom-made textures, object remixes, new stuff, and a complete foliage overhaul for all added vonBiomes. It took quite a lot of work hours, coffee, beer, and learning;) - If you like what you see be sure to leave an Endorsement, do a donation to tip me a beer, or two, or just have a happy dance in front of your screen.

Important note:
Do not override vonBiomes with other mods in general if you do not want to lose all environment and weather add-ons in the mod pack. This includes a whole lighting system with tons of sky bodies, dynamic lighting based on planet orbits, weather effects, plant leaf coloring based on sun-class, space nebulas, and (much) more.
Incompatible Mods:
For all Lighting & Environment FX:
- Ultravisuals & Weather (UVW) + any Mods requiring UVW
- Enhanced Lighting Mod
- Simple Enhanced Environment (Steam, also a lighting mod)
For all Foliage and Maps
- Xeno Optimize & Foliage
- Topo Map (can cause holes in the ground)
Mod Settings Requirements:
Do not override vonBiomes with another mod - that leads to losing parts of the mod and content!
Turn off Raytracing (on RTX cards) in MW5
Mod Options!
* Install the "Mod Options" Mod from the Nexus for.. well .. mod options!
Change the ambient volume or enable volumetric lighting, GI and more advanced settings & effects!
