Candle

[terze]

Hello,

Here is a version of the candle that was done for the houdini 9 road show, but mine is not fluids based, but particles based, and used point instancing lights and used the sss ops. hope you like.

Hey that is pretty cool, I really like the flame.

I am trying to put together a similar effect, but I am still trying to understand the shading system here.

May I ask how you put together your shader?

Great job!

its just a basic xray shader that takes the color values from the particles.

Thanks Terze,

I should mention that I am pretty new. I don't see the xray shader in shops, or in the material palette.

Is the xray shader something that you downloaded and added on? is it a shader that is easy to write?

Thanks,

~Ilan

Heres the network

just create a vex surface shop in vex

or a vop vex surface shop in shops

heres a screen grab of the network

Cool! I'm going to take a look at that, and figure out how it works.

Thanks again,

good flame movement.

The xray shader snapshot doesn't include premultiplying the diffuse with the opacity. Pretty much a necessity for a typical xray shader. You get a great look with the flame without premultiplying and that is fine. It is a good idea to have a toggle to allow the premultiply though.

I tweaked your shader out a bit and attached the file with the vop net in it. I also added support for the import of Cd and Alpha geometry attributes if they exist..
