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"

[Closed] Mesh Compositing

So. Mesh compositing. Are we going to have access to it this generation? From the few sparse details I've heard about it in UE3, it seemed like the superior solution to modular pawns. But it was closed off to regular UDK devs, b/c of the need for native access. With this hurdle now surpassed, will we be able to use mesh compositing at all? Or is there a far more robust third multi-mesh option in the works?

If I understrand you corretly, the thing you need is perfectly doable inside Blueprints. All you need to do is to add Mesh variables/components (static/instanced/skeletal), I actually tested it with modular skeletal mesh and I was suprised how easy it was.

No magic or special setup involved. I just added the components I needed and it just worked.

Can you please elaborate on this? I couldn't figure out how to get 'Set Master Pose' to work. Where does it go? Blueprint pic? :)

We do not have a mesh-composting feature in UE4, but you can easily make a modular character using multiple SkeletalMeshComponents and the 'MasterPoseComponent' feature. This is a much more flexible solution because you don't have to worry about texture layout/atlasing, a single material for all parts etc. The only downside is it uses a draw call per component, but this should not be a big problem unless you have hundreds of modular characters.

Actually, mesh compositing is available in UE4. Search the source code for "FSkeletalMeshMerge." You are correct that it requiring texture atlasing though, and this can be a lot of work. Here's the thread over on the UE forums where I got my answer: https://forums.unrealengine.com/showthread.php?1052-Does-UE4-have-mesh-compositing
