Honestly I dont think the new particle system is ready for prime time yet, theyre bug’s all over the place, and I hope they dont make it into the next release, The bugs are to numerus to name, and clearing the cache will only help some few of them. I also noticed that the abilty to start particle systems before the start frame are gone now also , (sta = negative number) I hope this is temporary as it will mean you will have to render a bunch of frames for an animation that youll just end up throwing away (since rendering is a very time intensive thing one doesnt need to waste it on anything). I made some very nice particle systems, only to make one change and the whole thing goes haywire… with no apparent way to fix it, except to save right before you do anything .
On newer builds(27 april)there is a really serious bug,hair particles get rendered only one time,if you try to render another time blender crashes.
The new particles are really good,people should help in finding bug and put them on the bug tracker.
I too think the particle system will need a lot of work. There has been lots of progress in the hair aspect of the new particle system due to the Blender Foundation project, but the regular particles have a lot of rough edges. Aside from possible bugs there are some other design problems:
Curve Guides: I know they are depreciated for use with hair / fur, but they still have a lot of very good uses. Currently particles don’t seem to respond to animated curve guides. Also there is no live update to particles when modifying the guides. (yuck)
Once particles / hairs are baked, we need to be able to key the control points using IPOs so that they can be manually manipulated over time.
Particles of all kinds need to generate motion vectors. Currently this is possible with hair / fur in b-spline mode, but not with normal particles. (Try doing motion blur in the node compositor when using particles as sparks, I have to resort to the old-skool motion blur, which sucks.)
I hadnt realized that the curve guides wernt working. Although the curve guides were really bad at guiding hair, they did have some uses with general particle systems, I hope theyre not being removed for good. They should be improved upon not removed, if anything we need more control over particle systems , not less.
@cekuhnen : thanks for the indication (clear cache)
@ all : can’t grab what this BAKEry is all for… i still just do my stuff and render… and it works. Or am i doing such simplistic basics that it just doesn’t matter?
You bake the particles so that you can then use the hair / fur tools on them. (i.e. brush, cut, etc…) If you don’t like what you’ve done, you un-bake it and it goes back to where it was before and you can start over.
I’m trying to texture particles properties like rough,size,lenght,clump,dens and so on with uv textures on a partial combed hair particles system(basically I want to comb fur and giving it some random behaviour with textures),but it seems texturing particles properties doesn’t work,only vertex group works.
Someone succeeded texturing particles properties with uv texture?
