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"

Grass with low GPU cost

Guys, I really need a recommendation for a grass mesh with a low GPU cost.

I've found out the hard way that the Kite demo grass meshes absolutely KILL FPS, even though I've used the grass foliage tool to put them in, so they're not separate instances of the same mesh.

Is there an alternative with a much lower rendering cost? Particularly something free and better still if its from epic?

The problem with the grass from the kite demo is not the meshes nor the polycount, is the cost of the shader. You can try replacing the textures of the grass textures with one that has less transparent sections.

You can also donwload the Infinity Blade's Grasslands demo, which also contains grass (in addition to other goodies).

But my advice would be for you to look into the shader of the grass you are having problems with and trying to make it simplier, aka less expensive by removing parts of it that you dont need.

Have a nice day!

Many thanks for that Bariudol, but I'm quite new to rendering, could you suggest which shaders should be removed for the best performance?

I'd really appreciate some help as I'm stuck fast!
