Better FBX Importer & Exporter v6.2.4 for Blender

Blender 2.82 - 4.4

https://superhivemarket.com/products/better-fbx-importer--exporter

• Blender is lack of native FBX support, when we import some older and newer FBX files, it often fails.  So I made a better FBX importer and exporter with official FBX SDK from scratch.  The add-on is compatible with all FBX versions, from ASCII to binary, from FBX 5.3 to FBX 2020.  I have tested the importer and exporter with about one hundred commercial FBX files which made by 3d digital artists in 3ds Max, Maya or Cinema 4D, the add-on can import and export these FBX files successfully.  The exported FBX and DAE files have been verified in Unity Engine 2021, Unreal Engine 4/5 and Godot Engine v4.1.1 with no issues.

• Scientific visualization tools for Blender.
• This is an extensible set of Python-based tools designed to simplify complex scientific visualization workflows in Blender.

• Flower Generator is a Geometry Nodes-based procedural generator for all kinds flowers. All available parameters are bundled into a single node group that can be accessed right from the modifiers panel or from within other Geometry Node groups.It allows you to change the growth of petals, sepals and stamen in various ways, allowing you to create flat flowers, double flowers, and countless others.

• JMesh Tools is a streamlined hard-surface modeling toolbox for Blender that turns common chores—booleans, bevels, arrays, and quick cutouts—into fast, repeatable actions. Built by Jayanam, it centers on a powerful Primitive Mode: press Ctrl + Shift + P, then sketch directly in the 3D Viewport to project circles, rectangles, polylines, and curves onto existing geometry in object, edit, or sculpt mode. From there, extrude and apply a boolean in one fluid motion to stamp panel cuts, vents, ports, and design lines with precision. 

• Easy Blend Normals is the fast, frustration-free way to make separate meshes look like a single, perfectly machined surface. With one click, it blends shading between two selected objects so seams, panel breaks, and boolean scars melt away—no fiddly data transfers or destructive hacks required. Just pick your active “main” mesh, select the target, hit the button, and get silky-smooth results in seconds.
