Ciao,
i'm the only that can't render particle system? (max 2013)
This happens with all particle systems and with all kind of particles (also instanced geometry).

Here the max file

Thanks
Luca

Maybe Max's procedural particle shapes don't work in Maxwell. Try using the instanced geometry option:

I didn't test it. :mrgreen:

I always use Particle Source and use a shape instance, and never have any issues. That's how I make grass.

Very nice "Particle-grass" Bubba! 8)

Yea it works with PFsource, but the "root of evil" is that i have to re-render old project(s) containing about one hundred of "old & different" particle systems.. and will be deadly slow re-setting everything to PFsource :(

Well that does sound like a problem. Maybe one of the Max plugin guys can give you an answer.

There's a bug in the current version of the Max 2013 plug-in which causes legacy particle systems to be skipped. Max 2012 and earlier are not affected. It will be fixed in the next build.

Leaving aside the bug, the plug-in exports legacy particles to the MaxwellParticles extension, so they will be rendered as spheres regardless of the type setting. It is possible to add the option to render them either as spheres, or as geometry. Would you need this setting?

Note that it's not possible to create instances with these systems. It's either procedural spheres or actual geometry (Max gives us all the particle meshes merged into a single big mesh if we ask for geometry data).

Good news :)
Thank you Mihnea!

Hi guys,
Do you have any info when this new build gonna be released? Because i have the same problem. For example SuperSpray or PArray which object as a emitter don't render in Maxwell. Before last update i didn't have that problem. Please help. Maybe i could download older version of Maxwell Max plugin ?

U told that u will fix this after update. And after the update the bug still remained.
When will u really fix it ?

This bug should be fixed by the latest plug-in update (2.7.12). Did you install that version?

If it still happens with the latest plug-in, please send me a scene which reproduces the problem at mihnea.balta@gmail.com.

I sent u an email but for others i will also put it here.

So the problem is, In maxwell (maxwell_2.5.1.0_patch-win64) and plugin (maxwell_max_2.5.9) it looks like that:
Image
In 3DS Max it look like that:

And in any other plugin higher than them particles looks like dots. And i'm talking here about maxwell (maxwell_2.7.20 patch-win64) and plugin (maxwell_max_2.7.12) also.
With them It looks like that:
Image

Maybe u have some answers for that kind of problem. And i'm talking here about any particle system using mesh shapes as particles.
Would be great if u could help.

Ah, I understand now. The particle system is rendered as spheres with the Maxwell particle procedural. We will add an option which decides between this behavior and exporting the meshes (which was what the 2.5 plug-in did). However, the shapes will not be rendered as instances; the whole particle system will be exported as a single mesh containing all the shapes.

If you need to render instanced shapes, you can use PFlow.

In PFlow is the same bug when using mesh particles.

You have to use the mesh instance operator in PFlow.
