Rendering a specific material

[waelfuzai]

Is it possible for octane to render inly one specific material. Without rendering the whole scene?. As this should save me alot of precious time

Hi,

do You mean to render objects with only one particular material? (if so, then No, there isn't a way to do this)
or
You want to have a material test scene, to tweak single material? (if so, then At least Standalone does have this option, not sure about Lightwave 3D)

what i mean is, if i have object with several material on it, and i want to render only one material of them as a separate pass.
is it possible, if not possible with Lightwave3D, then how to do it with the stand alone version.?

thank you

How I do this: Select desired material (surface) in Modeler and cut from object and paste into new, and save both objects as two new objects. Then use Render Layers and make desired material (now an object) a separate render layer from everything else. Render.

Yes, you can use a render layer to isolate and render only one object, but the layers only work at object level. You can't render only one material currently.

yes thank you
this is what i exactly did
i reduced all other materials opacity to 0%
separate the object on different layer
and the problem solved
although it took the same amount of rendering time as rendering the whole scene,
i thought it will take less time, because i am rendering only the wanted material

thank you anyway

waelfuzai, you do not need to change of opacity on anything, when you use Render Layers correctly... sounds like you weren't.

Render Layers is in the main Octane Render menu -- this is where you give objects unique render layer numbers. And then you enable Render Layers in Render Target > Layers.

So all you needed to do was separate that material into a new object (and the one you cut this from as new), give this object a unique render layer number, enable render layers and put that object's number in Layers to render field, then hit F9.

Edit: You can't be saying you reduced opacity of other surfaces in Modeler, to be able to select the one you want, right?..can't be.. no effing way that is your method of selecting and separating surfaces... Please tell me it isn't.
