could you use the Autoupdate, then select the particle tutorial, press rebuild and run it? (please use Autoupdate, and not 7z file, because I didn't update it this time)

Still the same.

are you sure that you're using the latest engine.pak from the Autoupdate?

Yes, Seba doesn't see anything too.

ok, later I'll upload another tests

I've sent you on e-mail a modified engine.pak with 1 feature temporarily disabled, could you let me know if the particles display?
I want to make sure that one thing is causing problems.

Yes. I see now this particle.

could you check the engine.pak from the second mail I've sent you just now?
I hope it should work ok now

I still can see them

ok, so if you can see them, then the problem is solved, this engine.pak will be included in the next engine version

Great info

How can I make my own particle image? I made some shape in GIMP with grey scale and converted to .gfx but when I loaded it in ME I had only square particles without this image.

drag and drop source image into Mesh Editor\Particle image window (not Converter)

Ok thanks
