I’m using Sketchup 2017 with Vray 3.6 for rendering.
Sometimes, random stuff happens with my model when it comes to lighting.
Day before yesterday, I put a rectangle light on a ceiling but it does not light up at all. I tried things like not making on the ceiling face directly but to no luck. I deleted it, made a new one - that worked for one render but in the next render and so on, it wont light up at all
Yesterday, I installed a 10 IES lights on a ceiling with exactly same properties. Surprisingly, only 3 of them lit up during the render. The other 7 wont light up at all. I analysed the different surfaces to see if there were any patterns but no luck again
I am totally confused and wasting a lot of time with this. If anyone can help solve my problem, I’d be really obliged.
