Problem with Particles Grid

A bug ?

When we try to use a Particle emitter from a simple plane, with grid mode…
The amount of particles is not correct !?
(for example if you put 4 for the grid resolution, you get 4 X 3 particles !!!
(and not 4 X 4)

Why ?

Thanks…

Seems to work ok for me in both blender 2.49b and the 2.55 beta.
You have a screenshot ?, blend file ?

Ok Richard,
It seems to work…

But, in fact the problem is with the split UV for the billboard render…
Look at this image :



and the result (not correct) : I try to convert this image in a particle plane…

Look at the scene :

Thanks !!!

No texture in your blend.
Substituting another image, is this what you are trying to achieve?
For this I changed the texture mapping from UV to Object, with the plane as the selected object. You are also going to get some distortion as you are using a perspective camera, if you change this to orthographic you will get perfect squares.

Yes, wonderful !
It’s exactly what I want to do…
Thank you very much…

Another question : split UV is limited to 100…so, if I want one particule for one pixel (for example in a 640 X 480 pixels image)…How can I do this ? Is it possible ?
