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"

Spritesheet for mesh for Particles

So I basically would like to use a sprite sheet material to be used on a mesh, which I then use as a mesh-particle. This to give me some more control over a few certain effects I have in mind.

Not sure how to explain it better than I just did.

I looked at the tappy chicken game to see how the chicken is sprite-animated... but I don't think that approach will suffice for particles. Unless I make a material instance for each particle, the particles would all be in sync. Which isnt what I want.. as I would like them to feel random. This is all but optimal.

Any thoughts? stuff to check out or advice on how to achieve this?

Hey Luos -

Ok I tired to read your mind and determine exactly what you are looking for and I think I have at least a starting point for you.

Here is the Material setup. You can see I am using the Dynamic Parameter to control the number of Us and Vs as well where along the animation timeline I want to show (ManualControl Parameter). You should be able to then set up a randomness by using a uniform min of 0 and max of 1 and make sure that Spawn Time Only is checked true.

Let me know if this isn't exactly what you wanted or how I can better answer your question and I will.
