Visualization of lighting in Revit. IES file.

[fominih.nsk]

I use an IES file in my roadway luminaire. Why does the light spot not change with the rotation of the lamp in visualization at an angle of 90 degrees? I've tried several IES from different manufacturers, it didn't help. Rotating the grid in the family also has no effect, the same light spot in the same position.

can you share the family?

i am using Elumtools and the analysis looks fine.

[curtisridenour]

What tool are you using for rendering?

[fominih.nsk]

Elumtools works good. Standard rendering tools in Revit do not work good.

[curtisridenour]

Sorry that it is not working within the Revit Rendering. At least you know it is not the IES file or the Family. They seems to be working fine.

Right, standard Renderer has some bugs to read correctly IES file, the problem is solved using some ADD Tools like Elumtools or Enscape.
