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"

Make a material that do a transition between two textures


I am doing a cable material (to make notice the player if is on or off) and I have a problem.

I need to do a material that changes to blue texture to yellow texture. Thats easy and I can do it. The problem is: I want to maje that blend (blue to yellow) in the cable direction (like a progress bar, that fills from left to right. I want the same to my material. The bar is blue and it fills from left to right with yellow)

Anyone knows how can Do that? I haven't see any tutorial for that, only for material blend (all the material)

Thanks or the help!

Inside your material:

You can use a simple linear gradient and a scalar parameter, so you can compare them with "IF" and plug the results on your "lerp" alpha.

Inside your blueprints you can create a dynamic material so you change the scalar parameter with a timeline when you want and it will result on a "linear wipe" effect, wich i think is what you want.

Vertex painting, Kinda complicated but after the video you get the core. I think you can work with that. https://www.youtube.com/watch?v=AS_y7Dui_1Y
