Update from 26.07.2018

New update was sent:
- Fixed water bug
- Added opportunity to use lightmaps for villa rooms that contain it (due to many requests)
- Added uv moving functionality for hook objects(by request)
- Added sunrays functionality

lightmaps
I never liked lighmaps, even if I knew that it can produce good qulity lighting, but it always static and require a lot of time to rebuild if some changes was made, also lightmaps CAN'T be used with dynamic objects so body, hairs, clothing and so on will always looks detached from scene, because they will ignorre lighmaps. Although, I got multiple requests for enabling lightmaps  - current solution experimental, I'm not sure how to mix lightmaps properly with dynamic lighting that was implemented in hook5. For now lightmaps will be multiplied with ambient color and scaled with ambient intensity - need test how it works and if you will had some thoughts then let me know.

uv sliding for hook objects
Opportunity set some speed for UV coordinates, to create moving/sliding textures. I used such thing in water shader where it required, not sure how it can be used else, but as I said I got request for this. To use this funtionality, like previous changes you need use override parameter in hook object section:
 override.SUBSET_NUM.diffuse.uvspeed   or
 override.SUBSET_NUM.normals.uvspeed or
 override.SUBSET_NUM.specular.uvspeed
Also I did not get any info about animated textures for hook objects that was implemented in previous update

sunrays
I implemented sunrays algorithm based on view vector tracing and added corresponded settings to level UI and section. Sunrays will work only if sun enabled and ray enabled also. I got results that I expected, but I can't tell that I'm happy with it, on my point of view the method to heavy and required to many steps checking that ray was bocked. But many steps affect performance to drastically, with this I'm assume this code experimantal and I will search another solution for this effect, but you can use it already because I'm think that property will be the same even if I change algorithm.
