I am a fairly new user of UE and I am doing some research regarding to use UE for product showcasing. So a mix of architectural viz + showing a product.
I have already managed to import meshes directly from Solid Works into UE with a plugin. Meshes are looking quite alright but theres a big problem:
when the lighting is not rebuilt, everything looks fine:
once I rebuilt lighting - artefacts everywhere .
Im totally aware that the artefacts in the lightmap are related to a bad UV map which is generated by UE. The thing is that I havent got time or experience or programs to manually unwrap the meshes.
Also, the previewed lightings looks good enough to me, so how can i get the program to just use that lighting, however it is created ?!
hope this questions makes sense to you…thanks in advance for useful advice.
