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"

Rendering to the same render target

Hello,

I'm working on some side project and I was wondering how I could render to the same render target multiple times in a single frame?

I've converted some 3D worldpositions and I want to render a circle at each of those positions. The world positions are dynamically genereated so I don't know how many there will be upfront. since I was not able to find a way to pass along multiple vector location to a material I tried rendering to the same render target over and over again. But this does not seem to work as wel.

     UKismetRenderingLibrary::ClearRenderTarget2D(this, m_RT, m_RT->ClearColor);
     for (UTextureRenderTarget2D* render_target : render_targets)
     {
         m_material instance->SetTextureParameterValue(TEXT("Existing"), m_RT);
         m_material instance->SetTextureParameterValue(TEXT("Additive"), render_target);
 
         UKismetRenderingLibrary::DrawMaterialToRenderTarget(this, m_RT, m_material instance);
     }

Kind Regards, Dyronix
