How to render pyro in RedShift?

Recommended Posts




Hi, I'm new to houdini. I'm trying to rendering pyro in RedShift.
I'm using Houdini 18.0 and RedShift 3.0.32.

I prepared rslightdome and rslight and applied rs_volume to pyro_import1(geometry). However I've got anything but very dark.

I am not sure what I am doing...

The only suspicious part is Volume parameters in Redshift OBJ.

There was Volume Enable Toggle in Volume parameters in tutorials I've watched.
Is this due to a difference in versions?


 Can anyone help me figuring out what is wrong?

Thank you

a few thing you need to do to render

-Make sure you have the lights contributing to the volume

-Be sure that you have a volume shader connected to an output

-Make sure that you are using the correct channels from the pyro output

-Play with the advanced tab and remap your values if you need to

-If you are using the pyropostprocess delete the shop_material (however I can remember if that was introduced in 18 or 18.5)

That should do it theoracally 

Other than that upload a .hip would be easier to see what is happening.

Thank you so much!
I could render pyro by adjusting the contributing Scale.
By the way what is contributing Scale?

You'd think a light would be unified by now, but it's not. So you have two brightness controls on the same Redshift light. Contribution scale is like intensity for polygons, only contribution scale is used to illuminate volumes.

Thank you!
I haven't know that only Contribution Kale is related to Volume.
I have learned some new things from you. Thank you so much!
