[Space Colonization node seed stability?]

Hello Timursq,

 

Thanks for your feedback.

 

The Space Colonization result should be stable if the seed and all input data remain unchanged. However, this node is very sensitive to its inputs, such as parent paths, attractor points/clouds, distribution nodes, and other connected modifiers. Even small upstream changes can affect the resulting branch structure.

But if almost any modification in the graph causes the result to change, I'd like to investigate it.

 

Could you please send me a 3ds Max file with this model? Also, please let me know which parameters or nodes you're changing when this happens.

This will help me check whether it's expected behavior or if there's a stability issue that needs to be fixed.

 

Thanks!

[GrowFX 2.2.0 and 3dsmax 2020 and RTX 3090 Crashes a lot]

Hello,

 

Thank you for the detailed report, and sorry for the trouble.

If the crashes are random and especially happen while changing nodes, inputs, or node order, the best way for me to investigate this is to check the actual scene. Space Colonization was significantly updated in recent versions, so it is very possible that there is a specific case in your model that triggers an instability.

Could you please send me the 3ds Max file that reproduces the problem via private message or email? If possible, please also include a short description of the steps that usually lead to the crash or freeze.

Once I have the file, I will investigate it and try to find the cause as soon as possible.

 

Best regards,
Eduard

[GrowFX 2.1.2 Crashes When Adding "After Mesh Modifiers"]

Hello chroma,

 

Thanks for your bug-report again!

 

Yes, I noticed a problem when I added the Wind modifier. If some branches are deleted with the Eraser modifier, Max crashes.
I've fixed it now, but I need to verify it with your Max file.
If you can, send it to me. We also fixed the 'h' issue in the Copyright Text, as far as I remember, but if it still remains, I need to check with your file.
So, if possible, please send me your Max files. You can send them to support@exlevel.com.
And what version of 3dsMax are you using? I'll send you an update right away.

 

Thanks!

[2.2 Баги]

Это Вы открыли редактор кривых, и в нем нет масштабирования поля с кривой, поскольку нет кропинга самой кривой в области просмотра.
При перемещении точки за пределы области просмотра, она выходит за эти границы, и потом при завершении манипуляции, область просмотра масштабируется так, чтобы кривая снова находилась в этой области, и не выходила за границы.
Если нужно увеличить область просмотра, можно просто растянуть окно больше за его края.
Или не открывать этот редактор, а просто выделив ноду кривой, приблизится к ней, сделать общий масштаб более 300%, и там также появится режим редактирования этой кривой.

 

Спасибо!

[2.2 Баги]

Добрый день, Азат!

Про изменение цветов понял, исправляем.
Я не понял про "скрыть вектор", что это за галочка такая?

Но кажется догадываюсь, если ноду выключать галочкой "On" на боковой панели, то да, я заметил, что объект не обновляется. При включении нормально, все обновляется. Но ноду можно также выключать кликнув по иконке самой ноды, и вот тут все работает.
Это тоже исправили, можете скачать обновление.

Спасибо за указанные баги!

[3ds Max stalls loading on GrowFX plugin in 3ds Max 2022]

Hi wallworm,

We found that this issue was related to worker thread creation during the loading of the .dlo file.

This has now been fixed. GrowFX no longer creates these threads during plugin loading. They are created later, only when a GrowFX object is created.

 

We have updated all installer files, so please download and install the latest build again from your account of the User panel.

 

Thanks!

Hello,

Thank you very much for your help and for testing the files on your side.

I found the cause of the issue.

In my screenshots, I changed the output path to simply "C:" to hide my Windows username and personal folder information before posting the images. However, the actual export location I was using was my Desktop folder, which is synchronized by OneDrive.

Following your suggestion, I tried exporting to a different local folder that is not synchronized by OneDrive, and the problem was immediately resolved. Both Pivot Painter 2 textures are now generated correctly, including the XVector/XExtent TGA file.

So it appears the issue was related to OneDrive synchronization or file access permissions during export, not to GrowFX itself or the models.

Thank you again for the quick response, for testing my files, and for helping me identify the source of the problem.

Best regards,
Fabio

 

Hello Fabio,

 

Thank you for the update. I'm glad everything is working correctly now and that both Pivot Painter 2 textures are generated as expected.

 

Thanks again for testing this and for sharing the result. This may be helpful for other users as well.

 

Best regards,
Eduard

Thank you for your reply.

I'm also sending screenshots of my export screen, but it seems everything is selected according to the tutorial.

The only file generated and exported is ...rgb_PivotPos_a_ParentIndexInt_UV_2.EXR

One detail: these grwfx files are version 1.9 and I converted them to 2.2.

 

Thank you for sending the files and screenshots.

 

I tested both of your scenes on my side, and both Pivot Painter 2 textures were generated correctly for each file:

MT_PM_V165_Phoenix_roebelenii_01_06_rgb_XVector_a_XExtentDividedby2048reaches2048_UV_2.TGAMT_PM_V165_Phoenix_roebelenii_01_06_rgb_PivotPos_a_ParentIndexInt_UV_2.EXRMT_PM_V125_Carpinus_betulus_01_06_rgb_XVector_a_XExtentDividedby2048reaches2048_UV_2.TGAMT_PM_V125_Carpinus_betulus_01_06_rgb_PivotPos_a_ParentIndexInt_UV_2.EXR

Your export settings look correct, so this does not seem to be caused by the model or by missing export options. The TGA texture should be generated automatically together with the EXR texture.

 

One thing I noticed in your screenshot is that the output folder is set directly to: C:\
Please try exporting to a normal writable subfolder instead, for example:
C:\Temp\GrowFX_Export\ or D:\GrowFX_Export\

Writing directly to the root of the system drive is not recommended. Depending on Windows permissions, security settings, antivirus, or controlled folder access, some files may fail to be created or overwritten there.

Also make sure that:
- Overwrite Existing Files is enabled.
- The old TGA file is not open in another application.
- The output folder is not read-only.

 

Also keep in mind: for wind animation setup in Unreal Engine, you should also group several hierarchy levels together by Path Color so that the final hierarchy has no more than about 4 main levels, for example: (trunk -> branches -> smaller branches -> leaves).

Please try exporting to a separate folder and let me know if the TGA texture is still not created.

 

Thanks!

Hello,

I am testing the new GrowFX 2.2 Unreal Engine export workflow using Pivot Painter 2.

I successfully export: ...

Hello,

 

The XVector/XExtent texture should be generated automatically when Export PivotPainter2 Textures is enabled. It does not require any additional settings.

 

It also does not require Create Hierarchy of Meshes or Weighted Pivot. These buttons generate intermediate objects that can be used with the original PivotPainter2.ms script. This is another way to obtain these textures, but it is a more time-consuming workflow.

For the new Unreal Engine export workflow, you can simply click Export in the Export to Unreal Engine dialog, and GrowFX should export an FBX file and two Pivot Painter 2 textures:

• Position and Parent Index texture
• X-Vector and X-Extent texture

If the second texture is not created in your case, please send me your model or a simplified test scene. I’ll check it and find out why this happens.

Regarding existing tree meshes, the workflow is intended to export GrowFX vegetation without splitting the tree into thousands of separate meshes. However, for existing non-GrowFX meshes, the result may depend on how the model is structured and what hierarchy/pivot information is available.

 

Thanks!

Hi. Thank for the response. Not its not my tree. Its a growfxfile a friend send to me for learn from maxtree v16.  And when im looking in the UV i look the zone in the meta mesh do this strange thins. Maybe its a problem whith the configuration in the UV Coordinates of the meta mesh. But i wanna to learn how i can fix this in the future.

 

Hi Gamundi0804,

 

Pay attention to the UVW weight% parameter in the MetaMesh node. If this value for the trunk is higher than that for the branches, the trunk's UVW texture will overlap the branches, as in your screenshot.

You can adjust this parameter to achieve the desired result.

 

Thanks!

[GrowFX 2.2.0 Released]

 

GrowFX 2.2.0 is now available

 

We are happy to announce the release of GrowFX 2.2.0.

 

This update adds compatibility with Autodesk 3ds Max 2027 and introduces several major new features for procedural plant modeling, organic branching, reusable setups, and game-engine workflows.

 

Main highlights in GrowFX 2.2.0:

• Export to Unreal Engine using the Pivot Painter 2 workflow.
• New Space Colonization node for generating crowns, fine branches, and organic branching structures.
• New Space Clouds: Sphere, Box, Custom Mesh, and Path.
• New Unified Skeleton node for combining several generated path structures into one continuous skeleton with shared radii, a single mesh, and continuous UV mapping.
• New GrowFX Reference node for creating reusable GrowFX setups and multiple variations based on one original object.
• Full compatibility with Autodesk 3ds Max 2027.
• New Simple Path Position node.
• Updated Curve node with inline editing, popup editing, and access to the legacy 3ds Max Curve control window.
• Updated Public Parameters Manager with multiple rollouts and drag-and-drop organization.
• Many internal improvements, stability fixes, and bug fixes.

 

Export to Unreal Engine

One of the most important additions in GrowFX 2.2.0 is the new export workflow for Unreal Engine.

GrowFX can now export plant models together with Pivot Painter 2 data, making it possible to use GrowFX vegetation in Unreal Engine with hierarchical wind animation. This workflow exports the model as FBX and generates the required Pivot Painter 2 textures for Unreal Engine materials.

 

In this example, the tree was created in GrowFX, exported to Unreal Engine, and animated using the Pivot Painter 2 workflow.
You can also download the source file, as well as FBX and texture files:

FraxinusExelsior.zip

 

Space Colonization examples

GrowFX 2.2.0 also introduces a new Space Colonization system. It can be used to generate natural-looking branching structures by filling defined spaces and following guide paths.

 

Example 1:

Max 2024 file:  Tree_06.max

Gfx file:  Tree_06.gfxTree_06.mat

 

In this example, Space Colonization is used to create a tree crown with fine organic branching. The branching structure is generated inside a defined space, making it easier to control the overall silhouette of the plant.

 

Example 2:

Max 2024 file:  Shrubs_01.max

Gfx file:  Shrubs_01.gfxShrubs_01.mat

 

This example shows how Space Clouds can be used to control the growth area. The new Sphere, Box, Custom Mesh, and Path cloud types make it possible to guide the generated branches in different ways depending on the model you want to create.

 

GrowFX Reference node

GrowFX 2.2.0 also introduces the new GrowFX Reference node.

This node allows one GrowFX object to reference another GrowFX object and use selected parameters exported through Public Parameter nodes. This makes it possible to build reusable plant setups and then create multiple variations from the same original object.

In this example, the tree on the left is the original base tree, while the trees on the right are several referenced variations with different tree heights.
Max 2024 file:  Tree_01.max

 

GrowFX 1.9.9 SP13

We have also updated GrowFX 1.9.9 to Service Pack 13.

GrowFX 1.9.9 SP13 adds compatibility with Autodesk 3ds Max 2027. It also includes compatibility improvements for the GrowFX 1.9.9 component included in GrowFX 2.2.0 and fixes a hierarchy generation bug.

How do you achieve this good looking results with the mapping? I am new whit growfx and i have this complex trunks and many metameshes between roots and branches for obtain the look i want and the mapping after the metamesh looks wrong. How i can fix the wrong tiling and blend the different parts together????

 

Apologize for the delay in replying!

 

I'm confused. Is this your tree in these pictures, and does it look incorrect?

Or is this not your tree, and you want the same result?

 

You can send me your tree, and I'll take a look and try to adjust it.

[Is it possible to get/set the curve graph for the stiffness or flexibility in the wind after mesh modifiers?]

Hello,

 

Ok, we'll add methods for managing curved graphs a little later. We're almost done with version 2.2.0, and we plan to release it, after which we'll add these methods.
I can't promise to add this for version 1.9.9, as these versions are very different, and we're not adding anything new to the old version.

[How to get the Public nodes dependency object names]

Hi j_forrester,

 

You can try this script:

fn walk obj =
(
    if (findItem visited obj) != 0 do return()
    append visited obj

    local deps = refs.dependsOn obj
    for d in deps do
    (
        if isValidNode d and d != root do
        (
            if (findItem result d) == 0 do append result d
        )
        walk d
    )
)

fn getAllDependencyNodes root =
(
    visited = #()
    result  = #()

    walk root
    result
)



deps = getAllDependencyNodes $        -- Selected your GrowFX object
for n in deps do format "%\n" n.name

 

This works for any version of GrowFX, as well as other objects

Thanks!
