Not sure if you guys gives a shit but if you're stoned like me during the covid times you can watch pretty much all of the latest series on InstaFlixxer. Been watching with my brother for the last couple of months =)

@Mauricio Finnley yea, have been using instaflixxer for since november myself :D

[@jasonpogi27]

Hi, I'm not sure if I missed something here, but the shadow location (light position) does not really changed even after I do CTRL+L (moving the sun) & "BUILD", still the same output from the earlier setup is showing. By the way, the tutorials are great.

[@theimageneers5161]

yes this is somehow a bug or a weird error , if u adjust the values on the panel options of the sun and sky that you will find on the right side , after you build it will give you the correct shadow and light timing that you have determined in the values

[@jasonpogi27]

@@theimageneers5161 alright I got it. Guess I have to forego the CTRL+L...could have been pretty handy. Thanks a lot.!!

Another great tutorial! I have two things that aren't working quite the same way as in the video. 1) When I disable Auto Exposure, my scene is very dark. 2) After building lighting, it seems like it works, but your video shows really nice bounced lighting, for example, on the underside of canopies or the ceilings over the porches. Mine are solid black. Any help appreciated!

[@theimageneers5161]

Thanks , after disabling auto exposure go to the exposure in the lit panel in your 3d viewport next to the show menu and disable exposure and adjust it based on your scene this will help bring your scene more brighter , if that dosnt solve the dark areas under the canopy just try to increase the light bounces in the lightmass setting menu and build your light again , hope that help

Hi! I was trying to find some tutorials, and this one is the best one! Congrats! When I import the datasmith all StaticMeshes comes in one layer. How can I import and have all the hierarchy layers as I had into 3dsmax? I see in your video before It happened too, and now you have three layers. Can you help me? I believe it is the same question that Wad has.

[@theimageneers5161]

Hi , thanks and hope these videos will be helpful enough for you , basically all what you need to do is to export them one by one so they can be in the same hierarchy as in the 3ds max , and also if you like here is a link for the data smith files exported and all what you need to do is to import them in UE4 www.dropbox.com/s/dt9luer5jgktfy2/DataSmith.7z?dl=0

[@Merazzi]

​@@theimageneers5161 Thanks, I solved importing each one. I was supposing could exist as an automatic way to import the same hierarchy. Btw, I was with the same problem with Sun+Sky resetting, then I saw your new video explaining how to correct this issue. Double thanks! =) You should create a room on telegram for your followers.

Cool work. Have you tried using dynamic lights or movable lights only in unreal engine archviz? Thank you

[@theimageneers5161]

Dynamic light is your choice as long as you dont care about the FPS and you gonna present on your machine , but if you gonna pass the final packaged product to your client you might find it useful to use stationary light to give you faster fps

Hi there , thanks for sharing your Q , getting this error could be due to many things but the best thing i would suggest to reimport your datasmith files and save as a anew level with no unreal utilities such sun sky .. etc , and check if the same problem still happening , otherwise if your still in the early stage of your project then its better verify the engine for epicluncher and create a new file and emigrate your project file to the new scene , hope that will help

maps need lighting rebuilt, i am stuck at this from hours, and building lighting is also stuck at 0% at preview quality. i cant a solution to it, this happens when i increase lightmap resolution of components to green color.

[@theimageneers5161]

can you please try the following , 1- make sure that the sun and sky light component ( directional light and sky light ) is set to static or stationary mobility 2 - add light importance volume around the project so the light build will only include whats inside the volume 3 - open the swarm agent that you will find in the task bar beside the clock ( in yellow color ) and clear the cache from the main menu 4- if the previous steps didn't help can you please create a new project and start a clean level and import the project and setup the light again and build the scene without changing the light map , please let us know if this didn't help , thanks

What to do if lightmap UV's are overlapping for some objects?

[@theimageneers5161]

This happen most of the time with heavily detailed objects such as furniture objects in this case you have to step in with your modeling software and try to minimize the number of polygons or maybe by separating some of the elements to help datasmith avoid overlapping lightmaps

what can i do with overlapped polygons ?

[@theimageneers5161]

hi , so overlapped polygons are always an issue inside the modeling software you are using and the best way to solve this is to either weld the vertices if they are 2 walls meeting at the corner or remove the extra face if its a double face on top of each other .
