Issues importing slopemap, crashing etc.


My terrain is 32km X 32km units large and I’ve got a nice landscape material for it. I followed Futurepoly’s tutorial: Pro Tips: Creating Terrain For Unreal 4-part 1 - YouTube I’ve saved out a .bmp map which selects the slopes of my terrain in world machine. In Photoshop I made it a .png, and the size is 32k x 32k, since that’s my total landscape size. This is where my isssues lie. I’m using World Composition.

My PC barely handles having all the tiles open, as it’s a rather large map. My PC is brand new, 16gb RAM, 1060 GTX, SSD etc. Either I run out of system memory and the engine crashes when I’ve opened all the tiles (making the whole computer laggy ofcourse), or if I’m lucky enough to try and import the slopemap, my whole PC just goes black.

The terrain consists of roughly 500 tiles, so it would be a pain to assign every tile’s slopemap manually. It can be done and it looks really good, but it would take ages.

I’ve tried: To set my switch file, I do think that this is the culprit of my PC going black when I try and import the slopemap, due to the PC running out of memory. Any tips on what I can do? I just bought this computer so a bigger rig is out of the question, hehe.

Update: I tried to split the slopemap in perfect percentages (25%) in order to lower the memory usage, and I selected 4x4 tiles from World Composition, in order to apply a slopemap to a smaller portion of the terrain. I’m wondering if I did this simple math wrong though, haha. I’ve got a 25% horizontal and vertical slopemap. This will be applied to 25% of the map which is 4x4 tiles. The total is 16x16 tiles. It sounds correct to me, but it’s not applying correctly. I am fairly certain that the top left of the slopemap equals the top left of the world composition tiles. I’m confused. :confused:
