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"

Layer Blend not working as expected.

When using Material Layers in conjunction with Material Layer Blend using RGB mask the layer at top reveals the background material in areas where mask is not 100%. I wish for the revealed material to be the one underneath it in the stack. I am new to UE4 so I'm sure I am missing something. Any help is much appreciated. Please see screen shots for further explanation. Thanks!

Layer blend is order independent. For pixels where sum of weight times blend for all layers yields less than 1, normalization can bring in layers with a weight of 0. Consider adjusting your blend maps or dropping LandscapeLayerBlend in favor of using your own order-dependent blend

Thanks for your response Deathrey. I'm not using the LandscapeLayerBlend; I am using the experimental material layers. Maybe this new feature is not order-dependent? I wonder how I set the weight of these "Material Layers"? I dont see any setting for weight. Is it possible to use a LandscapeLayerWeight node in the material? Any ideas or thoughts are appreciated.
