DP questions: soft lights, bumpmapping and pretty water

[Freemanoid]

Ok, I want to ask about soft lights.
As you can see in screenshot below, (engine - darkplaces) light have ugly shadows and looks poor.

Is it possible to make better, realistic lighting? Something like this :

(Screenshot of the same map but in 3ds max)

And the second question, about bumpmapping :

For example, I have in my map (orangemap.bsp) texture named "dev_wall01a.tga"

Here id1/textures/ I placed my texture named "dev_wall01a_bump.tga"
(Or id1/textures/orangemap/dev_wall01a_bump.tga)

And as you can see on first screenshot in this thread, there is nothing bumpmapping on walls.

What is wrong?
(Same I can say about all models)

And the last question, about water.
I installed "pretty water" (Pretty DP Water Pack v 0.2 by Zombie & Urre), then I patched all my maps with "id1vis"
Now, I have strange bug. See it on screenshots below.


As you can see, water on screenshots is different. And this is always happens if you look at water, and start to moving your view.
(Also, on water, there is no bumpmapping)

I make my maps in quark. for compiling I use standart txqbsp, vis, light. I need to use something else for more realistic effect?
How can I fix bug with water? I dont full understand. dpwater.pk3 already have some shader.

You can try hmap2 or q1rad.

q3map2 works with quake 1, but there is problem with original textures from quake 1.
Here screenshot :

Thanks for link I'll check it now.
About water. I paste here 2 screenshots. Water have different transparency. When you moving your cursor, but still looking at water, water transparency starting to changing very fast with light and dark, one by one. If you stop moving your mouse all is good. But if you walk and look at water it's transparency changing. And some reflections of objects (on 1st screenshot you can see players gun, but there is no such reflection on 2nd screenshot)
Sorry if I explain bad.

I've made video about "water bug"
Check it out here :

It's in .ogv format, but my media player classic plays it well.
