Hi All,

I've had a quick look through the forum so hopefully this isn't a repost,

Here's my problem:

I'm creating a coloured liquid from nParticles, the particle speed effects the incandesence so I converted the nParticles to a mesh.

Then I used the color set editor and a mentalRayVertexColor node to pipe the particle incandescence to the blinn incandescence.

When I render in the render view it looks exactly the way I expected. Happy days,

I wanted to render with mental ray so I could split the incandesence from the diffue and re-comp them later, however when I batch render the incandescence pass is rendered without any colour...

I'm rendering without any indirect light, to a 32bit EXR.

here is the render view

here is the batch Render

I hope this all makes sense, any suggestions as to what is causing this or how to fix would be most welcome.

Thanks in advance

Do you have multiple render layers?? It might be stupid but maybe you rendered only one of them...

Yes I have multiple layers, I rendered out all of them and all the others came out fine, the one with the particle effect was the only one that looked different,

When I render the layer with the particles in the render view it looks fine, it's only during batch render that it looks off.... 

ps. Thanks for the quick response!
