Recently joined Unreal as part of my teams evaluation on which engine to proceed with for an RPG. Initial impressions are that is has a lot of potential and is a powerful engine, although clearly designed for the higher end GPU. It’s not as well documented as other engines such as Unity, although Unity has a number of years over Unreal as far as the Indie market is concerned.
In terms of what you are getting from Epic’s licensing it is a very good deal, given you have access to the source code. On to the topic though - whilst experimenting with the editor I’ve come across a few issues with the landscaping. I’ve decided to take screenshots and post these. Other than a few over-complications in the editor, UE4 does have a lot going for it.
This one occurred after an auto-save; the height mapping disappeared. Before then though, whilst painting the textures the blackness was appearing. It only disappears when you paint a texture nearby. It might be that the material has an issue or there’s something else I’ve missed but the height map getting lost is a definite bug.
These screens show before and after. It occurred during the auto-save again and affected the terrain textures and height map. Shading and building couldn’t correct this although painting textures or heights has some limited success. When play testing the mesh was as it should be however the “visuals” weren’t.
I haven’t encountered these types of issues with the other major engines and their editors, so hopefully a subsequent patch will resolve these.
