This is by far the best series ive seen on lighting, and believe me I have probably seen them all. Lighting can make or break a project so I am always looking for imformation to improve my bakes. After watching this, I now have a waaay better understand how all of the settings influence each other, and which values i need to tweak to get the results I want. Thank you, thank you!
The red X issue you're referring to comes from 5 overlapping Stationary lights casting ~static~ shadows. When the 5th light is placed and overlaps at least 4 other static shadow casting Stationary lights(based on attenuation and cone shape), the smallest of the 5 will get the red X. The light with the red X means it will no longer cast static shadows, but you will still get baked indirect lighting and dynamic shadows. Other than that limitation, they share a similar dynamic lighting cost as a Movable light(ignoring dynamic shadow costs for Stationary per-object shadows and Movable whole scene shadows).
long time asking for the function to group stationary lights that will be operated together, that will bring great possibilities to the stationary lighting
Super nice series! I like how you're not only explaining the process as steps but also explaining the reason behind every modification. Thank you, man!
Great video! Interesting that all offline renders, you light without effecting gi. It's all controlled by camera exposure and everything else is taken care of but with unreal it's like the 90s where all lights are individually tweaked and are not really physical based. Great because you get more control but harder when showcasing a real world project what exactly will happen with specified lights. Learnt so much from this latest series.
Thank you for sharing your knowledge. You are explaining everthing so clearly. It makes everthing easy. Step by step, so perfect. It makes me happy to understand the whole thing for lighting. Thanks again. You are the best !
This series have been so helpful! Thank you so much i love how you take the time and explain how and why you are doing things. Its the first tutorial i am actually LEARNING from! Any chance of making a dungeon style lighting? I struggle with how to set a mood with different colors or lighting.
Really helpful. I tried UE4 a while back but decided to move away onto the same archviz path...now I decided to come back and with your lighting tutorials I've been able to get impressive results. BTW: I think it was already adressed but at 4:50 when you try to get the red cross on the spot light and cant...is because they are set to movable not stationary LOLZ. I might not add anything but really wanted to point that out XD
In forward rendering, you get a warning when there are too many overlapped dynamic lights. But in deferred rendering, which's the default in UE4 since a long time ago, it's not a big issue, cause the lights are fairly cheap. You probably could get 1000 lights(without shadows) and still get good performance.
Amazing video I learned a lot in this series! I have a question and I haven’t been able to find anything useful online. I hope it’s not a dumb question but did you change any viewport navigation control settings ? Because unfortunately I struggle a lot to navigate in unreal’s 3D space which is pretty bad for a developer. I tried to change it as close as Maya’s controls as I could but the default controls aren’t very comfortable for me, or maybe I just have to get used to it. Please let me know if you made any changes. Thank you!
I know the pains of software navigation controls. As a Maya user, I can sympathize. However, I like the navigation controls for UE4. Having used it long enough, it really doesn't bother me. I wouldn't change it.
Great series! just one question can you talk more about the material used at the lamp? (like the one used for the omni)! and really thanks for the link rgb to kelvin!!
I was about to ask the same thing. I'm trying to figure out how to make a material for a lampshade that actually glows from the light passing through it. Or do I just make an emissive material and "fake" it?
Thank you for doing this tutorials, it will help us a lot. Can I ask, how do you set the lights or environment back to default or off without deleting them and re-baking? I mean, I did turn off all lights,skylight and sun, but my scene is still lit? I also deleted the lights but still my scene is lit. Thank you.
I think he briefly mentions this in the part 1. In World Settings there is a checkbox for "Force no precomputed lighting". If you check that, and do a light build, it will delete all the previously generated lightmaps. Then you just uncheck the box and you're back to zero baked lights.
