I'm using LW2015. Does anyone have a step-by-step sequence I could follow for setting up a pair of simple render passes (beauty and RefD) for the daylight environment light reflecting off water? I find the menus in Octane Render Target and Render Passes rather obscure. In the IPR I can see both the Beauty and the RefD renders, but when I hit F10, I only get a strange Beauty/Plain Ref followed in the next frame by a black empty render - no highlights bouncing off water. Any help greatly appreciated. Thanks.

Hi,

It is weird that the F10 rendering doesn't save the same passes images that you can see in the IPR. Perhaps there is a problem with the image format, or the scene updating. If you want to send me the scene I could take a look at it here.

Thanks,

Thanks Juanjo,

Scene files attached below. At this stage I am only trying to render Beauty and RefD.
PS. 3 items attached.

Many thanks

David

Hi Juanjgon,

I'm still struggling to get the render passes to look like the IPR previews. See attached jpeg.

In the manual it says "I.e. each one of these requires its own film buffer that needs to be stored additionally to the main film buffer on the device." Is this referring to the the Compositing Buffer Export?

Files for this scene are in the previous post.

I think that the only problem here is that you have a layer defined in the scene, that is used to the final rendering, but in the IPR you have the "(all layers)" mode selected, that internally means that all the layers are disabled to render the IPR scene without them.

If you select your layer in the IPR, the rendering should match the information saved to the image files, as you can see in the attached image. FYI, the main difference is that the layers are rendered with the alpha channel enabled, so the environment background is lost.

Hope this helps,
-Juanjo

Hi Juanjgon,

When you say I "have a layer defined in the scene," I presume you mean "Reflection Direct"? I have checked Layer 1 and Reflection in the IPR but the render (below) still doesn't look the same as the IPR.

Hmm, but the image that you can see in the LightWave image viewer is always the beauty pass (the passes are not rendered to the LW image viewer). The reflection pass stored in the exr file, if you save it, is the same that you have in the IPR.

Thanks,

The DVI viewer you show is new to me. Where can I find it?
