And I think the last question
How to make my windows reflect hdri?I made GI from bitmap, but when put same bitmap on "background" (which is down to GI) nothing happens to my render

Finaly I managed to deal with fence textures..

Also, i would like to ask how to make smoth column? when I modelled, it somehow made itself to be with corners.

I had a look at your sample.

There are several issues:

1. You have not isolated materials with the same material. There was faces connected with different materials. (top left comment in my attachemtn)

2. Some faces had a displaced texture one the front, but another on its backside. (See the Entity Info window)

So how I understood, that, theese gaps will be at that places where diferent textures connects?
And how to remove texture from its backside?it puts automatically

The very first VfSU had no version number visible in the UI.
VfSU SR1.0 and SR1.5 had the version number in the About section of the Option window - should say something like; 1.00.74 or 1.05.30
The latest VfSU has the version number visible in Window -> Preferences -> Extensions -> V-Ray for Sketchup, something like 1.48.66

My version is 01.05.30

If you have multiple faces of the same displaced material you don't need to group each face. You only need to separate faces of different materials.

I't still doesnt work.. keep continuety is marked..

A sample model, part of the model, where the problem occurs.

What version of VfSU do you use?

V-Ray 7

@unknownuser said:

These gaps between that faces you displace, are they connected?

that faces are in component. On the 1-2nd images faces are only grouped. On the 3'rd image, only one way to activate displacement was: to make group for every face.

@unknownuser said:

Are they facing the same direction?

Yes, when I enable that view with faces dirrection, all faces are white.

@unknownuser said:

Have you ensured the Keep Continuity checkbox under the Displacement in the material?

I don't know exactly, I dont think so.. How to do this?

@unknownuser said:

Do you have a small sample?

Sample of what?
