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"

[Closed] Decals dont' look how I expected

I've been struggling with the decals. There doesn't seem to be any documentation so I've been using what I've seen in the demo maps (Specifically, the Reflections map with the graffiti decals. It took me a while to figure out why i couldn't get my decals to look like the ones in the reflections scene and it seems to be related to shadowing. As you can see below, where the sunlight is hitting the decal, it's behaving as expected, making it look as if the grass was painted red, while in the shadow, I can see what looks like a red-multiplied grass texture. alt text You can see a bigger issue in the demo map here: alt text I've tried about every combo of settings in the material editor, bit it's just not fixing this issue.

Did you tried to assign flat normal map to your decal ? I think I had similiar issue and it was related to not haveing normal map in material.

Thanks for the tip. I tried it, but the problem still exists. Maybe my writeup wasn't terribly clear. I like the "painted grass" look, it's what I was expecting, it just blends incorrectly in shadowed areas. Adding a normal overrides the existing source normal, making the decal look 'flat' however, the blending issue persists. alt text

I'm getting this same issue. Like in the Mobile demo map, if I put down a decal it doesn't show where there are shadows. It's like it doesn't receive the indirect lighting. I hope it's fixed soon.

Hey @sadtaco,

Sorry for the delay in response. This is an old Archive thread from our beta users, put here for reference. If you're still having issues with decals, please feel free to open a new question so we can address the issue there with updated information. Thanks!
