RailClone Pro (*) / Nested Railclone causes 3dsMax to crash with VRay GPU
« Last post by TR1151 on Today at 02:27:27 am »Hello,
I had been working for the past 3 years with nested railclone objects in 3dsMax 2021 and rendering them with VRay 6 GPU without any issues. I recently updated to 3dsMax 2025 and VRay 7 and the nested objects cause 3dsMax to crash when I try to render. Any thoughts?
I can revert to VRay 6 and see if it works, but I thought I might ask here before doing that.
Sample scene is attached.
Thank you.

I can't integrate this parameter into my head. It must be old age.

RailClone Pro (*) / Re: Spline from Autocad Problem
« Last post by Michal Karmazín on November 21, 2025, 09:32:42 am »Hi,
I'm sorry to hear you're having trouble with it. Could you please describe the issue in a bit more detail? Are the RailClone styles you're using based on the spline’s Material IDs? If so, let me mention that, as noted here on our forum:
"... upon my experience, in case of importing splines from a .dwg file, its Color is used for generating the 3ds max Material ID. If you want to avoid the Edit Spline modifier step - assigning the Red color to such spline (layer) should result in ID 1 / Yellow as ID2 (as the Red color should be indexed 1 (Yellow 2) in AutoCAD)."
I hope that helps.
Best regards,

RailClone Pro (*) / Spline from Autocad Problem
« Last post by HU0164 on November 21, 2025, 09:25:32 am »Hi,
I receive 2D AutoCAD DWG files from surveyors.
I am almost never able to apply a RailClone object to splines from DWG files.
What do I need to do to make it work?

Forest Pro (*) / Re: Use network paths for library & textures.
« Last post by iToo on November 20, 2025, 12:00:25 pm »I don't like idea of automatically searching textures in the paths what 3ds Max does using Project Paths/External Files. All textures should include the path to library. Even if I rare use any objects from library I constantly get a message about changing paths when I switch Max project folder.
Next Forest update will include a "relink" feature as option. Using it, library textures will include the full path to the library.

Work in Progress / Re: 50% row like a regular parquet
« Last post by Michal Karmazín on November 20, 2025, 08:49:49 am »Hi,
You can place a ‘half-sized’ Segment (adjust its size using the exported value from the main Segment via an Arithmetic Operator), then alternate the rows using a Sequence Operator. If you’d like, feel free to upload or send us your scene and we’ll be happy to take a look.
Let me mention that we acknowledge that RailClone has a steeper learning curve compared to Forest Pack. In order to help users become familiar with RailClone, we have an ongoing series of tutorials that you may find helpful, as well as detailed documentation. I would recommend checking our RailClone "Getting Started with RailClone" guide followed by our "Next Steps with RailClone" guide as well.
I hope this helps.

I'm sorry to hear you're facing trouble with it. Would you mind running a quick test using Forest Tools to export all items as instances before rendering? You can find this option under Utilities > More... > Forest Tools. For more information, please refer to our online reference guide. This test will help us figure out if the issue occurs during the conversion of the Forest object or not. Thanks in advance.
