I’ve been following the steps but the project doesn’t even compile, much less the plugin. I’ve bought Instalod but it seems silly to have to rebuild the plugin ourselves to make it work. Why not just deliver the versions prepared to just download them? Thanks.
Hello @EnonHernandez,
Could you please elaborate further on what is going wrong and whether you are possibly receiving any error messages?
We currently provide a single package that is compatible with multiple versions of Unreal Engine.
Thanks!
I made a C++ class in an empty bp project, after closing and compiling it I get this… , that is, I have not been able to add the plugin because the project does not want to compile, I have already installed everything that is required.
Hello @EnonHernandez,
Could I please clarify, are you able to compile a default, unmodified UE project? After discussing internally, it’s possible that some modifications to your Visual Studio setup may be necessary to build the UE project successfully.
Based on this article, can you confirm that the following modules are installed?
Thanks!
yes all its instaled and the same error
Thanks for confirming. I’ll mention this internally.
In the meantime, if you discover what might be the cause of the error when compiling a default UE project, it would be great to know the cause.

Hello @EnonHernandez,
Could you please try building the solution from Visual Studio? This way, you will be able to identify the exact errors you are getting and it will be easier to narrow the issue down. To do that, double click the .sln (Visual Studio Solution) file located at the root of the Unreal Engine project to open Visual Studio.
Once the solution opens, click on the “Local Windows Debugger” button (the green “play” button) on the top of the window.
Since your solution is not compiling correctly, you will get a message error once compilation has finished. Click no to close the popup message.
Then, on the window main menu, click on “View > Output” to open a window that should display logs, including errors and warnings, that happened during compilation.
Make sure that the “Show output from” filter is set to “Build” first, then select all text with Ctrl + A, copy with Ctrl + C and paste its contents into a text file.
Thanks!

Hello @EnonHernandez,
Based on the logs you have provided, it appears that you are not using the recommended toolchain MSVC and Windows SDK versions from UE.
Recommended versions:
| Software | Minimum Version | Recommended Version |
|---|---|---|
| MSVC | 14.38.33130 | 14.38.33130 |
| Windows SDK | 10.0.19041.0 | 10.0.22621.0 or newer |
User versions:
| Software | Installed Version |
|---|---|
| MSVC | 14.44.35209 |
| Windows SDK | 10.0.26100.0 |
It’s likely that this is what is causing the compilation errors. Hopefully with the recommended software versions installed, you’ll be able to compile an unmodified default UE project.
I’d like to note here that the errors you are seeing are related to your development setup and compiling a UE project itself and not related to the InstaLOD integration.
With that said, I’ll send you a DM with further steps to assist installing the InstaLOD integration.
Thanks!
Fixed now , unistall everything in MSVC and re install it
