Tropical South-East Asia Rainforest / Jungle Pack v1.0
Welcome to the Jungle! Roam the wilderness of the tropics in southeast Asia,
build your own jungle by combining lianas, palms, bamboos, and trees –
all you need is this pack of tropical assets, suitable for all kinds of “Tropical Asia” scenarios.
This pack is featuring both handmade props and photogrammetry-based assets,
and aims at giving you the best possible balance between realism and performance.
Most tree, rock, trunk and plant assets range between 50 and 8000 vertices
to ensure decent speed even on non-high-end computer systems.
The total mesh count is 82, including bananas, trees, ferns, rocks, trunks,
bamboos and many more items, some of them 3d-scanned via photogrammetry
to give a realistic, natural look for what we consider a pretty fair price.
The low polygon counts as a result of hard and efficient retopology work
may even make it possible to experiment with VR and mobile platform use.
Pivots centered to origins, models are rotated properly.
Most suitable for PC / Windows platform.
