    Thanks for spoiling me the game!

    Seldoon, I'm so, so sorry! I hate it when people spoil games for me so I know the feeling.. I didn't even know what game of MGS it was, I never actually played any of those games, it didn't even occur to me it could be the new game.

    Haha, I can't tell! I thought maybe there were some hidden spoilers I couldn't get simply cause I don't play MGS ^^

    Man chill on! I was joking! It's like who never played MGS on Psx!? Awesome Art btw!

    Hey guys ive been learning how to model the last month and im having an issue in UE4. I made all the models in this scene(basic obviously) pillars and walls. The walls are 500x500 squares, but have some odd lighting issue between them when I tile them. Its not a UV lightmap either.

    If any of you could know what is possibly causing this, id really appreciate it, thanks.

    It probably is that they are separate meshes, and rarely makes sense to split them up so much to make a wall like that. Combine them and give them a unified lightmap UV and it will go away

    That's caused by how lighting and shading is done by the engine. This type of level setup would cause problems with shading in any other engine as well. You have all these fragmented models all over the scene and the engine has to draw each of them separately and shading them before they appear into your screen. Look up "drawcalls" and understand how they work.


    UE4 isn't just a magical thing that makes everything look awesome whatever you do, it still has a lot of limitations which needs to be taken into consideration.


    In this situation either hide your seams behind pillars or make your ceiling, walls, whatever out of single mesh.

    Also make sure that you are snapping to the grid. It is easier to whitebox the scene/level with BSP and export the bsp to your modeling program, model your mesh,and reimport to replace the BSP. Rebuild your lighting as well. As WhiteDevil said, drawcalls are what matters at the end of the day.

    Do you mean combine them into one mesh? How would I go about doing that, or do you mean just model a new piece. Im slightly confused on why this would happen. Ive looked up a lot about modular design to make environments and even looked at some examples in engine, and none of them had this issue. Granted im using a very basic flat wall, but would this happen if I had a more extensive piece? Thanks for all the info though guys.

    Combine them into one mesh in whatever program you're modeling in (duplicate the planes several times, then attach/weld them together) and then make sure you have a new lightmap UV for this piece. Most modular environments have this issue, the difference is in how they hide the seams (either on a natural seam in the texture/mesh, or behind other geometry). In the realistic rendering example, the walls/floor/ceiling are just one purpose-built piece, and in the modular sci-fi environment the seams fall behind other geometry or in locations where a seam wouldn't look out of place.

    You can hide this effect with your textures/materials, too. Because the surface is a flat, light colour, it makes the seam really apparent. Look at these examples from the subway demo; the texture works well to hide the seam from the modular components and the obvious difference in shadowing (when you look at the scene in lighting-only mode). If you're going for a look that's less noisy then you have to find another way to hide the seams.

    Thanks for the info, that helped a lot.
