Landscape Material is Crashing

Hey there,

Branch: Binary

Build Version: 4.2.0

System Specs: 8gb Ram - Nvidia Geforce 550 ti - i3 core 3.3 ghz - Windows 7 64 - bit

Repro Steps: I’ve created a landscape material using a blend overlay node which is connecting a color map (4096x4096), and 5 landscape layer weight nodes (each texture is 512x512, including normals). I’ve done this hundreds of times in UDK and never had a problem. But in unreal engine 4 I can’t even apply the material, it crashes instantly! I have no idea how to fix this or what could be the problem. The editor does not seem to be running slowly and there aren’t any other glitches. No crash log appears after the crash, so I can’t send a screen capture. I have however attached screenshots of the material as well as the project logs.

Thanks in advance.

Please! Can anyone offer some advice or help? I’m behind schedule on a project and need an answer! Anyone? Hello…?

Hi dgonik,

All of your normal map layers are listed as Grass01, try changing that as they may simply be having a hard time determining which normal map to use on that texture.

Hmmm… that doesn’t seem to be the problem… I fixed it and the material still crashes, either straight after I apply it or right after I try to paint :confused: Could there be something wrong with the material setup it’self? (Although I used it in UDK just fine…) Maybe there’s some sort of bug? It almost seems like it’s a problem only related to painting on the landscape…

Hi dgonik,

Try to use the material in a new level with a flat landscape and see if it still crashes. If not it may be something with the landscape you are using.

Think I got it… It’s a hardware problem, my computer couldn’t keep up with the camera speed in the viewport, so I slowed it down a notch. Works fine now… (I know, kinda feel stupid now :D)
