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"

Particles facing wrong direction when using orthographic camera (PSA Velocity)

Hello, I noticed an issue with the particles when screen alignment is set on PSA Velocity and using an orthographic camera. The particles don't face the camera. Simple issue, but pretty annoying. Hope it can be fixed.

Godspeed, Etienne. alt text

Hey DynaMesh -

This issue had been fixed in an internally branch of the engine and should be an upcoming hot fix or major release of the engine.

Thank you for your report -

Great. Just checked with 4.6.1 and issue still there. Will keep an eye on further updates. Thanks.

This still seems to be an issue. Any idea when it will be fixed?

Hi Anthony -

As of 4.9.2, the issue has been corrected and particles with Velocity Alignment are visible in the Orthogonal Camera, assuming their velocities are not set to be perpendicular to the camera (plane on its side).


Thank You

Eric Ketchum

I've done some test and this still does not work correctly for cameras not looking at a YZ plane. They only work when the emitter is placed at (0,0,0) or very close to it.

In the attached images I have a camera looking at the XZ plane.

This issue persists still, in version 4.16.3. Following your link, the issue has been placed on "backlog". Any info on when a fix might be made would be greatly appreciated!

I have the same issue as well. Hope a fix is coming soon as this makes some effects basically impossible.

Same here, agreed.
