One of the reasons for learning to use Renderworks properly is so that I can use my client's 3D designs to analyse my lighting positions. I tried to illustrate this in a recent discussion about a display case in a museum project that had a shelf; it was pretty obvious from a section that we'd have shadow issues under the shelf, but I thought it would be good to be able to demonstrate that with a quick render to the client team. I attach an output of my model here.
The front lighting comes from two spots, arranged as per the light track positions in the room, and the spot settings of 10˚beam/20˚ spread to mimic the fixtures' performance. Under the overhanging elements of the case, I placed two linear fixtures that I made with the linear light tool - and set the output of the strips to 4000 lumens (an arbitrary value). The colour temperatures of the two types of fixture are deliberately different (3200K & 5600K)Light test - linear & spots.pdf so I can see where each light source is going.
My query is why has the spot fixture got such a nice smooth beam performance, whereas the linear fixture is producing a lot of 'noise' & pixellation? The render was set to final quality, as I wasn't sure which value to adjust in the custom settings.
Thank you for any pointers in improving this.
