Today I installed the latest D5 release to test it.
I noticed that IES lights only support 180° half dome space. In fact is not possible to assign a photometric file to a point light.
I think it’s very important to use and render all types of ies photometric files.
Also I noticed that is not possible to convert or replace a light from a type, for example point, to another type, I have to delete the inserted light and create it again.
