Last week was productive.
At first I've setup footsteps sounds for my character. Now he can step on different materials and get different sounds. It wasn't very hard to implement because I found a way to do the trick watching tutorial on YouTube.
Then I added jump animations and that was not easy. The problem with jump was in the real life we never jump immediately. But in the game we should do it in a moment. So the start and the end part of jump animation must be very very short. Usually I use Mixamo animations but for the jump I had to make animations in Blender manually. After some hours of work jump animations were ready. OBS capture with low quality is here 😖
One thing I hate I never can have a good capture quality with OBS. Forums said that's because OBS works bad with Unreal Editor. So I need to BUILD the game to capture it fine with Fraps. But building takes 3 hours with using all my PC resources on it.The next task was subtitles system. And here I was happy: UE4 has built-in subtitles. But very soon my happiness gone because built-in subtitles works only for short audio files which content can be converted in a single string. Timing pacing for long files doesn't work. So I decided to make my own subtitles system. I think my way to take subtitles from the single data table asset is even better than built-in system when I need to open every sound file to add subtitles in there. Moreover now I have control on the subtitles text and can change the system if I need.
When subtitles work was over I decided to fix lightmaps issues. The problem was in my modular walls. After light baking they got a strange shading on every piece of wall. BUT... when we weld all planar pieces in one big planar mesh shading problems go away and the walls lit properly. As long as my floor and ceiling use the same modular approach I have to remake them all. Oh...
Replacing one asset with another was so exciting I redesigned the stairs. They were made of stone and now they are made of wood.
Also I added some ceiling lamps in the halls. 
Revising my first quest I changed some speeches. Revising my second quest I decided to add a radio in it. I modelled this radio for 12 hours and finally it's finished.
The cool thing is it has a highlight on the front side. So in the darkness it looks like: 
Actually it's a real USSR receiver VEF-202.
Well, that's all for now. I hope on this week I'll finish quests polishing and on the next week I will release the demo. Anyway I need financial support from kickstarter as soon as possible because my own money is running out...
