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"

World aligned procedural texture

This has been annoying me constantly. I use a lot of procedural materials, and the WorldAlignedTexture node only supports texture objects. Is there an alternative?

Hey OhiraKyou -

You can always open the material function itself and copy the vector math directly into a material which would allow you to use Texture Sampler nodes as opposed to the called Texture Object nodes.

Texture Objects are required for using Material Functions and calling an inputed Texture Component. You could also create a Material Function in which you already input a texture sampler thus removing it as an input.

Thank You

I also cannot plug procedural code into Texture Sample nodes; it only accepts textures. Noise and gradients for example, return floats.

Hey OhiraKyou -

If you are wanting to use custom HLSL script you can input that code in a Custom node, and as long as it outputs a 3 Vector you should be able to us the World Aligned Texture Material Functions construction, but you will not be able to use the actual node itself.

Let me know if I need to clarify further -

The Texture Sample nodes used to align textures to the world in the WorldAlignedTexture function do not accept vectors; they only accept textures, which excludes procedural noise, gradients, and other float1-3 (vector) values. Copying the WorldAlignedTexture function is easy enough, but replacing the all-important Texture Sample nodes, which apply the world UVs, is the road block.
