Release Notes

What's new in GrowFX 2.1.0

• Added full compatibility with 3ds Max 2026 (64-bit).
• Improved plant generation performance! We increased the path generation speed from 2 to 25 times depending on the plant structure and the number of CPU cores.
• Added a new DrawPath node. With it, the user can draw branches or leaves directly in the viewport. Then you can edit the drawn branches by moving the starting positions or redrawing the branches. You can move some points, thereby changing the direction of the branch.
• Added a new Vertex Color Map Channel node, which allows you to change the Map Channel other than 0 for the Vertex Color system.
• Added a new UVW Custom node. With it, the user can write specific values to the UVW coordinates. Data can be obtained from Attribute nodes, and also modified using the Math nodes.
• Added a new Attribute IDs node. It allows the user to get path line indices, parent path line indices, or a branch level. Then this data can be passed, for example, to the UVW Custom node.
• Fixed issue with large number of objects in the Instanced Geometry when using Deform along path.
• Added Don't close the Node Editor option to the Node Editor Preferences. This allows you to keep the node editor open when you unselect a GrowFX object.
• Improved mesh generation process.
• Added Weighted pivot to the Creating Hierarchy group in the Preference parameters rollout. When on, pivots will be directed to the last point of the path.
• Added a MaxScript property: $.ShowIndexes.
• Some bugs are fixed.

What's new in GrowFX 2.0.1

• Added full compatibility with 3ds Max 2023, 2024 and 2025 (64-bit).

• Some bugs are fixed.

What's new in GrowFX 2.0.0

• Implemented a node-based editor instead of several rollout dialogs that allows you to manage all GrowFX components in one window. This gives us the opportunity to increase GrowFX functionality indefinitely by introducing various new types of nodes.
