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"

Hi -

Can you let me know what you are expecting with your Layered Material, it could be that your alpha texture input is backwards and you are rendering your top where you want you base and vice versa.

Thank You

i want the tilable materiel to be on top of the asset materiel. I inverted the alpha and it renders correctly however the tilable texture only comes on the 'white area of the alpha'. Is there another way of doing this. I want two materiels to be on top of each other blended together

Hi AzamKhan -

If you want the Materials to be blended directly on top of one another, use a Scalar Value of 0.5 in the alpha input instead of the texture Alpha. If you want certain places to be more of one material than the other use a LERP node with A set to 0.5 and B set to either 0 or 1 depending on whether you want to Base or Top Material to be more prevalent and the Alpha Texture plugged into the Alpha of the LERP. Finally, place the output of the LERP into you MaterialLayerBlend as the Alpha.

This happens if i try to increase the value of the tilable materiel with the alpha it works fine if both are set to 0.5

it works fine if both are set to 0.5

If 0.5 into the both of the LERPs gives you the results you are after, then you can just plug in a 0.5 into the Alpha Value of your Blend, it will save a few instruction counts.
