How to avoid getting a flat render using CVEX volume procedural?

[magneto]

Hi,

 

I was checking out CVEX volume procedurals but when I render, I am getting a flat render like below. I am using the same example in the help card, but I turned off Iso Surface and created a new Mantra ROP with better sampling.

 

I attached the scene just in case. Am I missing something?

 

 

 

 

Thanks

It seems you need a smoke material applied. Iso surface had most probably standard shader on it instead.

Thanks Symek, do I assign it to Surface Shader? I tried to create a material from the gallery but they don't show up at this level. Do you know how to do that? Nothing smoke related seem to show in the TAB menu. I never used a CVEX Volume Procedural before:

I think you just create Surface Shader Builder Shop and use VolumeModel VOP inside it (you need a density parameter at least).

 

edit: scene attached.

Thanks Symek, it works

 

I also tried copy pasting Basic Smoke contents but I think I didn't have a light in the scene (headlight option was off too), so it appeared black. But now everything is clear

But now everything is clear

 

... is smoky

 

as a matter of fact, you could just disconnect surface shader to render properly, as this would force Mantra to peak default smoke shader.

Thanks Symek, that's a great trick I lose the shadow parameters that way which help make the effect more pronounced but it's good to know that the shader is not needed.
