Problem with Normal Maps

[Shatten]

Hello all!
There is a question of the normals maps:

How exactly do you make normal maps in the game?
I make them like this:

Spoiler

 cards normal, then there is a problem with the light 

Spoiler

It looks Unity normally makes a height map (I guess) in the alpha channel

Spoiler

.  KS accepts these cards, but there is an example where the normal map works in its expected form. These normal maps work well

Spoiler

I use a shader KSP / Bumped

Thank you for attention

I can't really understand your question, as I don't know what you mean with "cards".

Your normal map seem ok-ish on that image. The alpha channel of the diffuse texture is usually interpreted as a specular map. not a height map. But this only is needed in ksp_specular or ksp_bumped_specular. For ksp_bumped your diffuse texture should be 24bit, without an alpha channels.

Question was that if I used the normal map RGB on items are placed correctly the shadows from the light

. The problem was solved renaming file name added at the end of "_NRM"
