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"

What ever is causing this issue is also blocking some work on our custom postprocess passes as well. Any love on the issue would be appreciated.

Thanks

/ Kyle

I've hit the same issue and fixed it by adding a ref count inc where I add my custom PostProcess and a ref count dec in the PostProcess::Process() function.

 // Called from PostProcessing.cpp
 AddCustomPostProcess()
 {
     // <snip>
     GSceneRenderTargets.AdjustGBufferRefCount(1);
 }
 
 // In CustomPostProcess.cpp
 CustomPostProcess::Process()
 {
     // <snip>
     GSceneRenderTargets.AdjustGBufferRefCount(-1);
 }

Though I am not sure if this is the correct solution..
