Rendering meshes as separate layers + Alpha channel?

[gsfcreator]

Hello there, Octane people!

when I save as .EXR, i get a file which contains multiple layers when I open it on photoshop (shadows, depth, etc).

I wanted to know if there is any way to have specific meshes saves into the .EXR as separate layers? lets say I have model A, model B, and background, and I wish each one of those to be on it's own layer...is it possible, and if yes - where to I tweak it?

the second thing I wanted to know is how to render with Alpha channel? when I wish to render only a figure and use it in another composition, I used to simply have only the figure on the scene, render on a black BG and save as PNG - and fire-fly saves alpha channel, thus the render is ready to be dragged-and-dropped into the composition. how do I achieve that with octane?

thanks in advance!

To render with an alpha channel, enable the Kernel->Alpha channel pin.

To render meshes in separate layers, set the layer for the Figure/Prop (in the "Layer" box), then in the Settings tree Render Layer->Enable and us the Active Layer Id to render out the layer you want. I suggest checking the Octane Standalone manual (docs.otoy.com) to see exactly how all this works).

Thanks, Paul! will do!

To anyone rendering in layers, is there any noticeable speed advantage to rendering in layers? That is, you render the background/scene elements as one layer and then say render a person in the foreground as another layer. For animation purposes, it would make sense to render a non moving background for only one frame and then the foreground/moving meshes frames as alphas.

I doubt there would be any speed advantage doing this.
