@12:37 AFAIK the reason for different meshes having different effects is that most meshes have their normals facing outwards. I.e. any texture is applied on the outer side of the mesh. If we use a mesh as a Skybox however, we are actually sitting inside the mesh, looking outward. If this mesh only has outward facing normals and a onesided material applied, this material is only shown when looking at the mesh from the outside, and is completely translucent when looked at from the inside. The skylight still produces correct lighting, but since there is nothing outside the mesh to reflect any of this light we just see a black void. To fix this, we must either use a mesh with inward facing normals (like the designated Skydome, or Skysphere, or use a twosided material which is shown on both sides of the mesh. Hope that helps shedding some light .. pun intended.
I use Unreal Engine 5.3.2. and HDRI DROP working fine in simulation mode but after I package the program the HDRI picture will only display on bottom of DOME. Do you have any idea for it?
Dear Jon, thank you for your time and effort. I create stories and only use renders, Would you by any chance know to render without rendering the HDRI image and only its lighting? I have tried to go to Geometry/Visible but when clicking that the lighting itself also disappears. Any advise would be greatly appreciated, All the best from Copenhagen, Adam
I have been using 3D software for 10 years now and I am currently working on a project that has to use UE5. The last couple of days have been just painful. Thanks for the tip about EXR/HDR files!
Great tutorial thank you. I brought in my HDR file and it's crazy bright. I adjusted the power to .25 and it looks good, but is that normal? Also when you rotate the HDRI background, it looks like only the BG rotates, not the image inside the skylight. Thoughts?
Dear Jon, I am sorry to bother you again. But I'm trying to light up an interior with Skylight together with the HDRI cube map and I can't get it to work. There is light outside the room (in the world) but not inside. Any ideas? Thank you in advance. Cheers, Adam
Hello. I have a problem. I wonder if you can help me please. I have two types of ilumination, one is Sun and another is HDRI. When I set up render with HDRI, the render comes out with Sun. I wonder if there is a way to configure HDRI as main ilumination source .
Thanks for the informations , i wonder if its possible to create a gradient texture in unreal engine to put in the hdri backdrop to have a procedural background for product rendering . I haven't found a way yet
Thank you so much. This is the best HDRI tutorial in UE5 by far that solved all of my problems and has answers to all of my question about it. Thank you for comprehensive and easy to understand instructions!
hii, your videos are always helpful, you are the only one i found who makes a video for a topic and we do not need to search for another video again! i mean you cover everything about the topic in a single video, lots of love, and i have a small request can we get a tutorial for how to work with aces for compositing s log footages with green screen and davinci ? i would really appreciate and lots of people who really struggling with this, i hope this msg reaches you:)
Hi, There is only one Hdri in my hdri file and I downloaded some Hdri from Hdri Heaven and when I want to upload them, I upload the Hdri and it does not appear at all annd it looks red ,I hope you can help me. thank u
Careful when messing around with the plugin material, it will affect every project, including the cloned projects. I did not work on a copy of the material, did not fully know what I was doing (trying to change the intensity in sequencer) and could not put at his starting values. Those parameters in the array are poorly named if named at all. The only way I found to fix it was to verify the engine version and that reset ALL plugins, and that medicine could be way worse than the disease if you changed other plugin settings and lost track of the changes overtime.
Sorry to hear that you're experiencing that man. I took a moment of my day to test and I didn't run into any issues. Sadly, Unreal just be stupid sometimes. If I may suggest, double check the camera exposure in your post process volume and/or camera post process settings. Lastly, the geometry you selected may actually be too small or too big. Go under the HDRI Backdrop scale and try multiple scales of the geo you are trying to solve. the HDRI back drop is technically not intended to swap geometry but my tutorial here is the work around. . Hope this helps! Have a nice day to you as well :)
5 months later and i have a solution. I had the same issue and using the sphere_inversenormals geometry instead of the normal sphere fixed the issue for me. sometimes you just have to play around with some things when softwares dont work exactly how you want them to. its just apart of learning. no need for the dislike this was a great video!!! found this out in like 5 minutes btw lol
In case you didn’t find out yet. Change the Skylight‘s settings to use the HDRI (which will provide the lighting) and set the Skysphere (or the standard Skydome, whichever you use) to use a simple white material. The skydome is just for the optics (so how you will see it in the scene). The skylight is the actor which actually produces the lighting. If the skylight doesn‘t have an HDRI assigned it will kind of reflect was is shown on the Skydome, otherwise it completely ignores what is shown on the skydome and generates lighting according to the set up HDRI. Hope that helps.
