Hi there good people. I’m a novice UE4 user and have been doing various tutorials, I’ve ran into a problem. I hope someone can spare a few minutes and see if they can spot what I’m not doing correctly. I was following a tutorial on localised fog. It worked fine. Better than fine. I made a couple of additions (added panners to the textures, creating the illusion of drifting thicknesses of fog), and it looked much better than I had hoped for. Then I played with the view distance, bumping that right up and at that point my world fell apart.
Well… it didn’t fall apart but it did look really odd. The skybox would go white everytime I moved the camera - in editor or in level, black peripheral vision. So getting the view distance back stopped that. The tutorial also talks about using r.volumetricfogpixelsize 256 and running that command through at Begin Play. I think I did that right, really not sure. I didn’t see any improvement. What did start happening though, was that no longer did I have a nicely undulating fog. No good people. No, I have created a wibblywobbly mess at best. This is a video of my settings and results. Under that is a original tutorial. After spending six hours this morning trying to track down what I’ve done, restarting from scratch four times, I reinstalled 4.21 - no difference. I’ve double checked everything stat and they look to me to be the same.
My Settings and results: Damn dancing Fog. Settings. - YouTube
edit - Here is a short video of the settings at correct levels for the end of the tutorial. The results look nice I guess, but that’s not what should be happening.: Fog being annoying and not doing what it's told. Bad Fog. - YouTube
Original tutorial : UE4 Tutorial - Local Volumetric Fog 1/3 - Basics - Unreal Engine 4 - YouTube
I’m hoping it’s something really simple that for some reason I’ve become blind to.
Help!
