Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Help, light changes color when I press play

Please Help. I have a level that changes color when I hit play. I have deleted EVERYTHING and put in a simple floor, 1 light and 1 cube brush. No post process volume, no color grading. Game mode set to default. Everything set to default. And still, after I compile it looks fine, but if I hit play, it turns purpleish. It started happening after I finished a level for an architectural visualization, so i need to fix it instead of redoing everything in a new project or level, so I duplicated it and started deleting everything to find out the problem. I can't. If a start a new level it doesn't behave this way (hit play and lighting seems fine) alt text I think it must be level specific, but I can't find what I must have changed. Please Help!!

I tried everything I could think of, but couldn't make the level work correctly again. The only fix i could come up with was to use the copy-paste method to a new level. Created an empty empty level, and copy-pasted folder by folder, including all lights and effects, and everything worked as expected. If I ever find what was wrong I'll post it. but this is a work around for now. Thanks for the help!

And you did not change the colors of the light in your Level Blueprint? This also happen when you delete the light and put a new one? Weird, since you also have no post processing. Maybe something about the material, can you show it or is it a simple texture on the Unreal BSP?

It's not material related, all materials act the same. I deleted all lights and meshes, volumes and skylight, then created a new box brush and put a point light. Everything is default. But I still get the purplish hue. Is there a way to copy all the meshes from one level to another? Not duplicating the level, but get all the level meshes from one level to another, sort of a copy-paste method. Any ideas are appreciated, thanks

Yeah sure, just select all the meshes in your World Outliner, ctrl+c, change the map, click on the root of your World Outliner and ctrl+v.
