I complied 4.26 Source from GitHub and set it up on my perforce. Now the problem comes when using UGS to compile the engine it stops saying.
Engine\Plugins\VirtualProduction\VCamCore\Source\VCamCore\VCamCore.Build.cs(5,14) : error CS0101: The namespace '<global namespace>' already contains a definition for 'VCamCore
ubt>
Engine\Plugins\VirtualProduction\VCamCore\Source\VCamCoreEditor\VCamCoreEditor.build.cs(5,14) : error CS0101: The namespace ‘’ already contains a definition for ‘VCamCoreEditor’
ubt>
Engine\Plugins\VirtualProduction\VCamCore\Source\VCamInput\VCamInput.build.cs(5,14) : error CS0101: The namespace ‘’ already contains a definition for ‘VCamInput’
ubt> ERROR: Unable to compile source files.
How do I fix this ?
