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"

Where is the Pixar USD support?


At GDC it was announced that UE4 has support for USD, I can't find any reference to it in the latest 4.15. Where would I find this, I can't seem to find it in the UE4 source either, has it not been committed?

Cheers, -S

Product Version: UE 4.15

I did not follow each bit of the GDC but I found at least something and I would assume, that they are working on it and that it will take some time until it is ready.

News I found: https://uploadvr.com/epic-games-unreal-engine-april/

TL:DR with Quotations: "Epic has also partnered with Disney’s Pixar Animation Studio to have Unreal Engine 4 and the VR Editor support Pixar’s Universal Scene Description (USD) 3D graphics pipeline. Epic showed the coral reef from Finding Dory and characters Crush the sea turtle and Mr. Ray the manta ray running in UE4." "Pixar wants to add more plug-ins for creatives beyond Autodesk Maya, so UE4 now opens up new opportunities for companies working in VR." " "We know the film industry will like it,” Ridge added. “We will increasingly use USD here. Hopefully, we will keep working with Pixar to make it awesome for every use case we can imagine. Right now we are working on USD import, but at some point we will probably be able to generate USD files as well.” "

In the last sentence they say, that they "are working on USD import", that's why I think that it is going to come and that it is not there yet. And if everything goes well you are maybe even able to generate USD files inside of UE4. We will see, I guess.

Thanks VizualTek,

Yes I saw that little bit at the end, I assumed that they were referring to a more robust implementation for public consumption. It's a little puzzling then that they can demo anything at all if they are really only working import right now, I would have assumed that some form of the import process would be found in the source tree but there is no reference to it at all.

Especially if you consider they are trying to release something in April, there should be some code prototypes or at least something there.. I guess we will just have to wait for now since I can't seem to be able to ask them directly.
