I don't have a name for this mod as of yet, however I have quite extensive plans for it and have made significant progress. I need help though, I'm looking for anyone who can code complex Minecraft modifications. I'm also looking for someone who can program animations for mobs as well as someone who knows their way around Minecraft's world-generation. However if you believe you can help in any other way, feel free to send me a message letting me know what you can offer.
To cut to the chase, this mod will overhaul the ecosystem of Minecraft, however the first thing I plan is to add a fair few animals to the game. I've already designed a plethora of birds and will continue working on some mammals and reptiles in the weeks to come. The animals so far are fully textured and modelled.
Please note that the models pictured far are not at the scale at which they will be in game-
White-Bellied Sea Eagle
