Lands Design Crash on Rhino 8 (NETCore) - Load Error

Plug Ins RhinoLands (Lands Design)
1

Hello,

I am experiencing an issue where Rhino Lands works perfectly on my system, but Lands Design fails to run when using [SetDotNetRuntime=NETCore v8].

Lands Design works fine on other runtimes (.NET Framework v7, v8), and (.NETCore v7), but with NETCore v8 specifically, it crashes the moment I start working (immediately after loading Grasshopper and all other definitions). This happens when I launch the program using the “Lands Design” desktop shortcut.

I attempted a workaround by launching Rhino directly, then going to Options > Plugins. I am able to successfully load Tibidabo.rhp, but when I try to load Lands.rhp, it fails and shows the error in the attached screenshot.

My questions are:

  1. Why is this happening?

  2. Do I have to stick with .NET Framework or NETCore v7 instead of NETCore v8?

  3. If I switch runtimes, will I lose any new features or experience a decrease in workflow performance?

  4. Extra Question: Does Lands Design lack specific object selection commands compared to standard Rhino? (I couldn’t find them).

Note: The issue persists even after uninstalling V-Ray for Rhino v7.0 and VisualARQ v3.3 (which were removed a month ago).

System Information:

  • Rhino: v8.21

  • Lands Design: v6.2.2

  • Grasshopper: v1.0.0008

  • OS: Windows 11 24H2

  • CPU: Core i7 10750H

  • GPU: Nvidia RTX 2060 6GB

Thank you.

Hi @حق_المشاريع_الحساب,

This is a known bug in Lands Design 6.2. This issue has already been fixed in Lands Design 6.3 and 6.4. You can download the update from the following page:
