Hello, I am currently working on an architectural project on Openstudio. The project runs well on the Openstudio and I don't have any problems. And I want to advance my project by adding components from Bcl. I can download them from Bcl but when I try to investigate them as a material or try to add them on my construction set, I drag them in to the boxes where they should be, and they don't show up. I cannot do anything with them. Materials that don't come from Bcl, work well. Materials that I downloaded from Bcl don't work. Do you have any idea why I'm having this kind of problem?
