Hello,
I have a problem with reflection capture actors. I have a big water translucent surface (translucent, surfacetranslucencyvolume, ssr, single sided) composed of many separate mesh tiles. I have reflection captures under the surface, and even if their radius are small, I see bad artifacts on the surface (some tiles are darker then other). This does not happen with unreal engine 4.8.
Hello Nero81af,
I have some questions to help me narrow down the source of the issue.
- When you upgraded your project, did you use the ‘Convert in Place’ option or the ‘Open a Copy’ option?
- Have you attempted to place the sphere reflection capture actor above the waters surface to see if this resolves the issue?
- Would you mind showing me the material properties of your water?
I would highly suggest taking a look at the Reflection Environment Documentation we have. It goes over how to troubleshoot your own reflections, and the proper way to place reflection capture actors to get the most out of your reflections.
Let me know if you have any other questions.
Thank you,
hello,
I’ve just choosen to convert in place. Actually placing reflection captures above the surface solves the problem. Why is that so? I’ve reduced material to have no input, just translucent, surface volume, ssr and it still shows the issue, even if underwater radius is really small reflection captures are far below the surface!
Thanks!
The problem was resolved because your material is single sided and you are placing the sphere reflection capture actor below the waters surface. In other words, there is no reflection information to capture from that angle, so it is going to render black.
Remember, the placement of your capture actors is the correct locations is important to gaining the most out of your reflection environment. Using a single large actor over your scene will not always give the best results. Placing a semi large one and smaller ones to increase the captured detail in areas needed are ways to optimize your performance and still get high quality reflections.
Cheers,
I have a skylight tho! Anyway, Thanks for the clarification and the fix
