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"

Writing on glass effect

I want to have an glass office door with writing on it. I've using images with transparent backgrounds in HUDs with no problem. I cannot figure out how to create a material with transparency.

Thanks in advance!

Cheers

its actually rather simple. all you need to do have a basic translucent material is to change the blend mode to translucent (see picture below). just select the material node in the graph and you will be able to modify its properties in the details panel. then connect a image or script to the opacity pin, in this case i used the alpha channel from a texture. the opacity is a 0-1 or black-white value where black is translucent and white is opaque. there is also another blend mode called masked which will also make sections of the material fully translucent but it uses the opacity mask pin instead.

I don't have mats with transparency. When I import images with transparency they look like the attached.

THose textures likely do have transprent parts. The preview in the engine doesnt know how to represent areas without alpha so it just takes the last known pixel and repeats that. If you setup a basic material as ive shown you will see that it should work just fine
