Looks like you have some lightmap errors, in radiant press Shift+L and make sure the lightmaps arn't streched out or too dense.

It's my "first time" with mapping at all. I can't understand those squares. Can You decipher those screenshots for me ?

The first screen is lightmap mode, it shows the grid on how big lighting will effect that particular brushe/patch; the second is how the engine will render the patch/brush as smooth or rough. Basically smooth is more detailed clean edge, this is great for far away low-poly patches to make them look smoother, rough is like the name rougher and not as detailed.

Most likely no, but yes could be possibly. See if the missing texture areas resemble those of the coordinates.

It's useless I've checked all specified errors and warnings and it's not working... Maybe my texture was badly converted. assman settings on screenshot base texture dds DXT5 interpolated alpha.

Might be wrong here but are you talking about the cross mesh fence panel If so i would not do it alpha just a normal texture when you convert it Might help try it and retexture it R1

I agree with R1. For solid textures you don't want it to blend, it essentially blends into nothing. So use on textures you don't want to see through. Also when you use , you don't need an alpha channel. gl

It's done "blendFunc" in assman must be set to "replace". Any other setting will mix textures blendings "alphaTest" to "GE128" This setting read black&white alpha channel Texture format is .TGA 32 bit (in .tga only 32bit has alpha channel)
