Stoke Atmospheric

Deprecated Stoke MX Beta Bug Reports
1

I think this is a bug, but it could also very well be something I am doing wrong. Steps:

  1. I did a super quick sim
  2. added Stoke Atmospheric
  3. Added stoke “field” to Atmospheric

Render scanline, nothing shows up.

  1. Added magma modifier, input vector (1,1,1) output color.
  2. Add Spotlight, check “atmospheric shadows” (but I did not turn on shadows)

Render scanline, crashes Max.

Stoke Atmospheric is supposed to work like Krakatoa Atmospheric right?

Specifically it seems to crash when I try to render after I add the input color in the magma modifier.

Stoke Atmospheric lets you pick Stoke Field sources, while Krakatoa Atmospheric lets you pick Particle sources.

I created a Stoke Field Magma and a default Spot light (no shadows, no changes).
In the Field Magma, connected a Float 0.1 to the Density output.
Added a Stoke Atmospheric and picked the Field Magma.
Rendered in Scanline - Got correct shaded volumetric box.

Then I made a Stoke Field Sim.
In the Initial flow, I set Velocity to 0,0,100
Set Density to Position->Magnitude->Less(20.0)->ToFloat which gave me a little hemi-sphere at the base of the origin.
Did not touch the Sim flow.
Added to the Atmospheric and rendered - got a column of density moving up.

This was in Max 2013. Will test 2014 next. No crashes so far.

If you can provide a scene or exact steps to reproduce the crash, plus the Max version you are running, it would be very appreciated.

Neither Stoke Field Sim or Stoke Field Magma accept Magma modifiers. Where did you add a Magma modifier?

To the main Stoke object.

Perhaps it’s me that’s misunderstood Stoke Atmospheric and what it’s meant to render.

Oh shoot, it sounds like you used a Stoke Particles simulation and tried to render that?
Stoke Particles Sim should not be a valid source of the Atmospheric, I will have to fix the filter to prevent you from picking it.
And it should not crash, I just tried and it did not crash for me in Max 2013, even with a Magma that sets the Color channel.

Stoke Atmospheric is meant to be used with the Field objects, not with particles. The Krakatoa Atmospheric is meant to be used with particles.

I see now, ok, thanks. Very cool.

It would be cool if you could provide a scene so I can see what is crashing. Post it here, or send it via our ticket system: support.thinkboxsoftware.com/
