Unpleasantly seriously long.
What was I doing all that time?
1. I changed my hardware. It is not the most powerful PC on the Earth but gtx960 is far better than 9600gt.
One '0' less - a lot of power more. Beside that, I changed CPU, motherboard, and RAM too but the difference's not that big.
2. Installing Windows...
It wasn't suppose to last 3 days but it did. Installation failed on every possible step. Process was painful, long, painful, boring, frustrating and fucking painful.
Oh! and at the time I needed to update the shit out of Win8 to finally get my Win10,
my internet provider had some kind of issues with providing the internet.
3. Lollygagging.
4. Doing that:
It is not something I'm proud of. Not yet.
-materials have no textures nor the normal maps;
-Stones, rocks, and grass models are made in less than 10 minutes each;
-everything is a placeholder;
BUT
-landscape material automatically paints cliffs with grey, plains with green, and everything in between with brown;
-Green, Grey and Brown are material functions so I can change behavior of one layer without messing with others. Also, that means I can add to them textures separately;
-grass is generated procedurally - which basically means everywhere where landscape is green the grass appears, with density based on how green the surface is;
-rocks and stones are added as grass, but less dense;
-if I want to change something that the "algorithm" fucked up (or, more likely, I simply want to change it) I can paint it manually;
-grass WAVES ~~~~~~~~~~~~~ :D
Considering the fact all I did I did in one day, still being newbie to Unreal Engine 4, it's not that bad.
I'll be working on that.
So long - hopefully not too long.
