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"

Subtractive Blueprint Object

I was wondering if i could make a blueprint object class spawn in as a subtractive object so it would make a space in a long object and moving at the same time.

hi, have you been able to do what you were working on? because I am trying to do the same thing and I have tried various things: decals, moving vertices in render target, and also location based opacity. problem with location based opacity is, that although it creates the effect as it moves, the effect does not stay there permanently to fake the removal process. if there could be way to, for example, create many instances of the this sphere opacity in run-time for any generated path and in blueprint, that would be awesome. do you have any suggestions?

Hi night_tig3r_13,

If you are talking about the BSP additive and subtractive geometry, they can't be referenced by blueprint and can't be manipulated at run-time.

However here is one possible solution, you could create a material with Location Based Opacity and add that to a blueprint. Here is a tutorial on how to set that up.

Another way would be to create the effect in a modeling program by animating it.

I need to play ground digging. BSP is not supported in realtime and seems cannot control APEX cloth in blueprints neither. What would be your suggestion to simulate excavator works?
