Thanks for the feedback and good tips.
I’ll spend some more time on the editor weekend, and will hopefully get around to adding some of your pointers to the wiki. I’ve already fixed the confusion about what to select (so selecting the bounding box should work for exporting) and it will be online with the next update.
In response to your questions:
- The best frame to use will depend on what kind of effect you’re going for and which calculation method you’re using.
- If using Velocity or Angular Velocity, I’ve gotten the best results selecting a frame around the middle (if 32 frames lifetime, around 15-20), just to give the forces some time to influence the particles.
- If using Distance, pick the frame at which the particles have traveled around the distance you will want them to travel in a second in the engine.
- Sadly, it wasn’t possible to export FGA files from the engine the last time I checked (4.7, I think).
Something else that’s not included in the wiki yet that I just figured out a couple of days ago: If you use Distance as the calculation method, you can actually use Blender’s Particle Edit mode to paint (comb?) directions. You’ll have to uncheck Keep Root in the particle edit Tools tab options, and check Draw Particles to be able to see what you’re doing. will only work if the the particle cache is baked, and can produce some pretty cool effects.
edit 11/01/15: I just updated the tool with some recent changes (presets, export selection fix), but probably will not get around to editing the wiki today.
