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] Deffered Decals on Unlit Materials

Deferred decal actors seem not to appear on surfaces that have unlit materials.

In the screenshots here we have a decal actor and two boxes. One box has a lit material on it. The other one switches from unlit to lit.

I wonder if this is a known issue? If it is an issue, is there a timeline on when it might be resolved (if possible)? If it isn't is there a way we can cast decals on Unlit materials that I am perhaps missing?

Hi Theo -

This behavior is expected as Unlit means that no shader computation is done and as decals modify those shading attributes you would not see any effect.

You can achieve the look of an unlit material while keeping the shader computations by assigning a zero to Base Color and Specular and your default texture or color into Emissive Color.

Here is an example:

Thank You
