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"

Material Expression Function Input can't choose TextureExternal

Hi there.

I tried to set TextureExternal with Input Type in Material Expression Function Input node but I can not select it.

It seems that they are shifted one by one from the Volume Texture.

I would like to put media texture RTT into my custom function node, but can not I still use it?

Is there any workaround? Since my vide texture is large(4kx2k), I would like to use it directly if possible.

Reproduction is easy.

  1. Create NewMaterialFunction

  2. Put FuntionInput node

  3. Select Input Type Funtion Input TextureExternal

Type will be null.
