I work in the architecture field and I love the idea of getting accurate measurements from my 3d models inside blender. I am specially excited about the lux measuring tools as I have real-world problems that could be solved using them. However I'd love to see a convenient way to convert the default sky texture EV values into lux (as I understand this could already be achieved) as combined with the sun position add-on could be a powerful combination for daylight analysis.
Thank you for you amazing work!
Thank you for your comment!
When using the default sky texture, which includes sunlight, setting the add-on's EV compensation value to 9–10EV can reproduce typical real-world lux levels.
Since light changes relatively, the ratio of external shadows, internal shadows, and artificial lighting becomes crucial in CG. The relationship between the sun and the sky varies significantly by region and cloud/atmospheric conditions, so there is no absolute value. Therefore, you must measure and reference the illuminance value or EV value for your desired time of day and location.
I've always felt that working on a scene while you configure view layers, for prototyping and comparing options, to be a mess and a time hurdle more than anything else. For me the biggest time saver is the ability to batch configure visibility of collections. I no longer need to be switching between layers and filling up my vram pool just to toggle one newly added collection off.
thank you so much!
