  12. What sort of FPS do you get? And what is your computers specs?

      1. Hi Raghu! great work man!

        what do you mean by “portals” on each window? do you mean you use the bounce card technique?


  15. hey man, great works, can you show us your lightmaps density ?

  16. any tutorial on materials creation? thanks

  17. Hey there Raghu! Thanks for the tuts, they are really explanatory and helpful! I’m starting on unreal and working my way up to photorealism. Just tested your config on my new project and it worked great on preview quality my build took only 1h to finnnish for an entire apartment. My problem is when I try building it on better quality! It takes forever to build. Could you help me a little bit on the configs? Thanks in advance!

  18. Hello,
    Hope you are doing good. I have seen your unreal engine videos, they are just awesome.
    I am looking for someone who can help me in my architectural visualization in ue4. I am not talking about the basic lighting I can send you the screenshots and renders as far as I have done.

    I need someone to guide me further for architectural visualization in Ue4.

    Video tutorials are not compulsory you can help me by giving screenshots or verbally guidance.

    Let me know what will be the charges for that I mean how much in total.
    Thanks in advance looking forward to hear from you.

  19. i set same lightmass setup

    but too much time to cache ,QQ

  20. I Dont know how just it took 30minutes
    I have a I7 and tooks more than 8hs

  21. Hello,

    Great job. Very realistic. I tried your settings on my scene but couldn’t get the same result. Always getting light tearings and something like smoke on surfaces. I wonder if I am making any mistake while setting the scene in 3ds max and exporting. How are you doing the uvw unwrap and which settings are you using on fbx export dialog box?

    Thank you

  22. Nice little project. I’ll be taking my first steps with Unreal Engine 5 over the next few weeks. I hope I can do it as well.
