Importing Embergen>Blender

Support Other Software

Hi. I recently started using Embergen for my work sims.
I just love it, super recommended to anyone needing smoke/fire sims.

I wanted to ask if anyone in the forum has experience tweaking the shaders/attributes embedded in the OpenVDB file exported from Embergen to Blender. I would like to know if you use the attributes in the file and how to implement them. Trying to use the velocity attribute to shade with a gradient the steam flux.

I am working with steam simulations:

Embergen_Steam
Embergen_Steam1151×636 113 KB

Blender_Viewport
Blender_Viewport1080×606 115 KB

I needed to crank up the volume density a lot to see the volume.

Attributes embedded in the file:

OpenVDB_Attributes
OpenVDB_Attributes401×835 38.3 KB

But when I try to check how they behave, I can not see any change of color in the speed x for example:

MaterialSteam
MaterialSteam806×327 30.6 KB

Viewport Attributes
Viewport Attributes1166×662 187 KB

I can not see any change in information by typing the velocity_x or y attribute in the attribute node.

Am I doing it correctly?

Thank you

Did you find a solution for this?

I suppose that he understood that its viewer node was plugged into the wrong socket.
Shortcut plugs it into the Surface socket instead of the Volume one.

instead of velocity do you have try density temperature or flames?
