Glass Reflection Problem - Can you help me, please?

[nitfus]

I've got a problem with the reflection. I think I've already checked everything, without any good results. I tried putting the simplest vray material, deleting all the scene lights, changing HDRI maps, changing rendering parameters... nothing has helped.

 

The triangles of glass reflect light in a strange way. The weird thing is that rawreflection and rawrefraction passes seem to be alright. Please, help me.

Check normals of the polygons

?

I think you should make some environment objects instead of using HDRI. The easiest way is create a plane and map it with an image that shown reflection environment (such as city image or anything else you want). Put this plane behind your camera and correct its position (x,y,z) until you get good result of your render.

+1 !

Test you hrd on a simple sphere... just to see.

 

Another thing : perhaps you've things to do with smoothing groups...?

Thank you very much for your replies. The "edit normals" modifier solved the problem, but I will also try rest of your tips and see how it will work, just to practise:).
