Motion blur is completely insane.
I don’t understand what algorithm tyflow is using to place the particles. But not where the phoenix is. I don’t know what to do. Since foam scattering on GPU doesn’t work yet, I decided to try to do it via vraymtl. And I can not. Motion blur reads the weather on Mars or Jupiter, but not what the phoenix gives out.
I don’t know what to do now. I need it to work, but it won’t 
max 22 vray5 phx rtx
Just turn off physcam motionblur, and render - partciles in place. turn it on - particles invisible. Maybe high motionblur settings, but what settings to try ? Also, can’t seem to have scale from phx to instancer Sad sad sad

WOW. Production and tyflow - GPU RTX reads tyflow particles correctly (they are in place with foam shader), while production - not. Will investigate further.
Hey Paul,
Indeed there is a known issue when using V-Ray Instancer with Phoenix and motion blur. I will bump the priority on that.
As a workaround for the moment using tyFlow seems to be working from my tests.
Yeah, for GPU it works, but not for production (tyflow). BTW - maybe you can shed some light on GPU foam shading ? I mean in priority list. GPU is so much faster.
I tried to mimic the foam shader look - so far unsuccessful Is it kind of each cell in additive mode ?
Foam shader is the jewel in the crown of the phoenix. When I try to render in something else, I can’t even come close to achieving this beauty.
The Particle Shader does some internal optimizations that mimic something like the Thin-walled mode in the V-Ray material, but this is still not supported on the GPU yet.
I hope we can get to improving the Particle Shader shading on the GPU soon.
Any news on foam particle shader on GPU ?
Nothing that we can share for now but as soon as we have something ready I will update the thread.
