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"

Editing texture opacity - Minecraft textures

I'm playing around with texturing minecraft style blocks in the texture editor. I want to be able to increase and decrease the opacity of the cracking texture - this way I can add code to make the cracks slowly fade in as the player breaks the block down.

So how can I change the circled texture sample's opacity? As you can see the texture is very cracked, how can I fade the cracking in or out?

Thank you :)

Add a Lerp (hold down L and left mouseclick), put the cracks into the A-slot. Put a value of 1 into the B slot of the lerp. Now in the alpha, you can use a scalar (Hold down S & left click) Plug the lerp into the B of that multiply.

Now play with that Scalar. 0 = cracked, 1 = not cracked. (or other way around)
