Slastraf Posted March 3 Share Posted March 3 Hi, I want to have a 100% black background. When I set the ambient light to (0,0,0) it will still be a dark grey. I tried to import cubemap from https://docs.unrealengine.com/4.26/en-US/RenderingAndGraphics/Textures/Cubemaps/CreatingCubemaps/ However Ultra Engine will not import these I tried a .exr cubemap from https://polyhaven.com/hdris with the same issue. These could be easily edited in gimp to be just a black image. How would I make an al black environment ? Quote Link to comment Share on other sites More sharing options...
klepto2 Posted March 3 Share Posted March 3 You can try this: To have fully black ambient you can try to lower the iblintensity : https://www.ultraengine.com/learn/World_SetIblIntensity?lang=cpp 1 Quote Intel® Core™ i7-8550U @ 1.80 Ghz 16GB RAM INTEL UHD Graphics 620 Windows 10 Pro 64-Bit-Version Link to comment Share on other sites More sharing options...
Thirsty Panther Posted March 3 Share Posted March 3 I'm trying to find time to do a full beginners guide to importing Cubemaps/ Skyboxes into UltraEngine. These are the basic steps: - Download a HDRI (exr) image (Polyhaven) - Download Kleptos PBR Texture Generator and extract. - Run the texture generator and load in your HDRI image by "File- Import Panorama" - Your image will load into the viewport on the right handside. - Click on "Save PBR Environment" - Open the folder you ran the Texture Generator from and you will see two new files. One will be your sky_diffuse and the other will be sky_specular. I recommend that you rename these so that they don't get overwritten when you generate another scene. Something like Bluesky1 or Cloudysky1 etc. - In UltraEngine Editor. Under the scene tab click on the title of your map. Underneath in the environment section. Select the dropdown next to background and browse to where your secular sky image is. Then do the same for the secular image and finally load in the diffuse image in the diffuse section. 1 Quote Link to comment Share on other sites More sharing options...

Slastraf Posted March 3 Author Share Posted March 3 sadly the tool crashes for me. Windows 11 It will crash after clicking import panorama. Quote Link to comment Share on other sites More sharing options...
Thirsty Panther Posted March 4 Share Posted March 4 I'm on Windows 11 and it works fine for me. If you can post your HDRI I will convert it for you. Quote Link to comment Share on other sites More sharing options...
