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"

??How to Blur a TextureParameter??

Is there any way to blur a texture parameter in material editor? I know that spiral blur can blur TextureObjects. But I need my texture to be a parameter but that can not be plugged into the sprial blur node :(

SpiralBlur function requires TextureObject to sample from, but if you want to change it in material instance, you can copy all the nodes from that function into material itself.

And I want to ask you - are you sure you need spiral blur? You can also blur texture with custom hlsl code.

This does not work because inside spiral blur is already custom hlsl code :( And the "Tex" does only read texture object and I Dont know how to solve this.

I now ended up with sampling my texture by a specific offset. If anybody knows how to write this in hlsl code please tell me.
