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"

GPU particles "colliding" with objects in front of it

Please excuse the confusing title but I have some troubles figuring out the issue. I'm using the GPU typedata so I can have large amounts of particles and I'm running into some issue when collision is toggled on.

Here it's acting as it should, the particles are killed once they hit the cube, and as you can see the little rectangle on the right isn't in the path of the particles, so it doesn't affect them. alt text

But if I move the camera behind the mentioned rectangle, the particles stop short and are killed. alt text

As I said before, the same events happen regardless of whether I'm using stop, bounce or kill as collision response. I'm looking to understand better why that happens and if I can do anything about it, as far as I know GPU particles use scene depth to calculate collisions, so maybe it's just the way it works and I can't do anything about it, but still it feels like something is off.

Update : checked once again, and it actually bounces in the case where it's set to bounce, I thought wrong.
