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"

Convert float4 (SceneTexure) to Texture?


I want to take my SceneTexture:CustomStencil channel, modify it and then I want to apply a gaussian blur. For that blur I use a custom expression with following shader:

 float3 val = Texture2DSample(Tex, TexSampler, UV);
 //Horizontal blur
 for(int i = 0; i<horizontalSize; i++)
   val += Texture2DSample(Tex, TexSampler, UV+float2(i*texStepSize,0));
   val += Texture2DSample(Tex, TexSampler, UV+float2(-i*texStepSize,0));

 //Vertical blur
 for(int i = 0; i<verticalSize; i++)
   val += Texture2DSample(Tex, TexSampler, UV+float2(0,i*texStepSize));
   val += Texture2DSample(Tex, TexSampler, UV+float2(0,-i*texStepSize));
 val /= verticalSize*2+horizontalSize*2+1;
 return val;

If I use a Texture object, it works, but SceneTexture only outputs float4 values and not Texture2D. How can I get Texture2D out of that float4 values? Is there any converter function?

Had you ever found a way to do this?
