I’ve added it to GitHub; you can download it from there and easily install it by simply copying it to Documents\3DCoat2026\UserPrefs\Scripts\cExtensions\

Got it carrots! Thank you, I will be testing it out. Thanks!

Hey! Found what seems like a bug in 2026 RC2. Pressing CTRL for preview in the node room is not working. Thanks for checking it out!

3DCoat 2026.07 RC
portable zip
3DCoat-2026-07.exe
3DCoatTextura-2026-07.exe
3DCoatPrint-2026-07.exe

- Holding Ctrl over a knot in components with the NGVoxel behavior now correctly previews its effect on raymarching
- Added support for applying Node Graph presets from the NGVolumes category directly to volume objects, automatically creating the necessary Voxel layer if it doesn't already exist.
- Significantly accelerated the rendering of node previews and channel viewing (via CTRL+hover), while eliminating lag, unnecessary loading popups, and fixing bugs with black material previews and layer masking.

- Fixed an issue where a connection between knots could not be established on the first attempt.
- When saving a NodeGraph, the same category and folder used when loading it are suggested by default.

I'm having an issue pressing 'v' to colour pick while doing hand painting.  It's picking  up grey colours and not the colour on my layer.    Sometimes if I press it multiple times, it will eventually get the correct colour.

This is on versions 2026.06 and 2026.07 using ppp on a uv'd mesh.

Edit: I'm guessing it's at times sampling the layer as a mask vs the actual colour.

I think this needs to somehow be clearer.

Also, editing the curvature map and ao maps is great...but there should be a non-destructive way to do it.

Recently tried out the new 2026.07 build and found some issues with node previews. I share here what I found. Hope it helps.

The issue is related to this ?

In 3DCoat, pressing the V key (the default hotkey for the Eyedropper) can be used to pick a color in two ways:

Single-tap: Selects the exact flat color directly from your 3D model.

Double-tap (or hovering and tapping again): Samples the color from the screen space, which includes lighting, shadows, and post-processing effects.

Painting over a single square with one face, got this result. Some squares dividing the UV space and a diagonal line appear.

The effect is more noticeable if you select View > Show Displaced Mesh

I will try that out.  But I'm curious if anyone else is having the same experience.

Windows 3DCoat 2026.08 RC
Portable 3DCoat, 3DCoat Textura, 3DCoat Print
3DCoat-2026-08.exe

- Added the new inGizmoTransform node, which connects to the UVWTexture, TriPlanar, and FragCoord nodes to control texture position, rotation, and scaling.
- Selecting a node with transform properties now automatically spawns an interactive 3D Gizmo in the viewport, letting you visually move, rotate, and scale it in perfect, two-way sync with the node's numeric values.
- Fixed an issue in the node graph where a locked preview would prevent you from temporarily previewing other nodes by hovering over them with Ctrl pressed.
- Fixed a bug in orthographic projection where models would only update after releasing the brush stroke, as the camera's performance optimization incorrectly assumed the model was out of view.
- A Projection mapping mode has been added to the nodes.
- Resolved critical normal mapping issues on sculpt objects, ensuring that fine surface details are correctly preserved even when using Soft Displacement

- Support for matrix-type properties in the node system
- Bugs and crashes have been fixed.
- Added the highly requested 'Auto Pick' and 'Ghosted' options to the top bar in the Print3D room
- Significantly accelerated the rendering of node previews and channel viewing (via CTRL+hover), while eliminating lag, unnecessary loading popups, and fixing bugs with black material previews and layer masking.
