RENDER COLORED SMOKE

[bennyho]

Hi Everyone

 

I am new to Houdini. I study three methods to make colored smoke. I can simulate color particles from all of methods but I can not render out colored smoke. As for method 3, more frustrated on the pcopen of material builder. I can not write out particles at all, there is no smoke to render out neither. I really need some help to know how to render colored smoke or pyro after simulation. sorry can't upload file so only use youtube to point out my questions.

 

1.      Method 1:

   I only can render grey smoke but can not render colored smoke at 9:18 of video

   No idea why?

 

2.      Method 2:

I set up a material pyro shader to render. I only can render grey smoke again not colored smoke. No idea why?

 

3.      Method 3:

I follow up video to make the path for point cloud texture, but can’t write out anything after rendering at 30:27 of video. No any smoke at this time.

 

Hope guy can give a help to solve the above issue. No idea where I missing.

 

Thanks in advance

An attempt here (and older attemps a few posts earlier)

Or just wait for H17 in a few days, where its built in.

(edit)

Oh, for rendering just bind Cd to your material:

For extra control put a colour correct in the middle, and/or connect cd to the emitcolor for different effects:

Hi Mestela

Appreciate for your help. It's funny for me to think wrong direction. I only know pyro shader or custom shader to render colored smoke. I don't know to use volume shader core to render this case. I will study this linking soon. tkx

Hi Mestela

After checking your ways, I found I still can't set up shader properly. I have no idea how to use volumeshadercore as shader because I can't pick up volumeshadercore from material of render in object. I only can choice shaders like uniform volume or pyroshader from material.

How to setup bind and volumeshadercore as shader? I try material builder but I can't connect properly them between surface globals and surface output or output collect.

If possible, can you kindly inform how to set up material for colored smoke? I am using Houdini 16.5 now.

Thanks in advance.
