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"

Landscape Paints Squares?

It seems that when i try to paint with layers it paints with squares instead of the normal circle brush. This happens with both the tutorial materials and the current one I'm using alt text

Hello Gunnar0,

After filling the landscape with your layered material did you paint the entire landscape. I have found that by doing so helps eliminate issues such as this. I will paint the entire landscape with grass or whatever texture I want as my base that covers most of my landscape. After you paint one of your layers it will compile as it will for all layers, as it will for all layers the first time painted, but afterward you should see a drastic difference.

I'm confused by what you mean, and no I didn't paint the whole landscape .

So, what can happen is the landscapes estimates where your texture should be drawn. The landscape is designed to use vertices to calculate where you paint. So, when you start painting, the engine will determine where the paint is based off of the vertices you paint. This also applies to the distance between the vertices.

Generally, I see a completely black landscape when I apply my layer material. What I will do is take one of the layers from my material and paint the entire landscape. This way there is information on all of the landscapes vertices. This eliminates the landscape from guessing what distance from a vertex you have painted. Without painting the entire landscape the landscapes vertices have no information. So, when you add a layer for the first time, the landscape returns a value of 0 for any vertex that has not been painted. The landscape then fills in the grid where it knows vertices exist. This too is a non accurate guess as to where the paint should be.
