Creates a medium scale fire and spark simulation in SOPs that is converted to 2D using COPs tools.

On this page

The stylized fire shelf tool consists of a medium scale fire and particle simulation integrated into Copernicus to create a 2D stylized flame look.

Pyro simulation in the composite view. Color space: ACES, Voxels Size: 0.05.

Important Nodes

copnet1

The 2D look is created using nodes and rendered inside the copnet1.

create_camera1

create_camera1 node provides a default camera with the setup that is used to generate the cop image.

integratevolume

The integratevolume node inside copnet1 integrates VDB layers into cops using a camera_ref input, which takes the layer from world space to image space.

Learning from this example

To...Do this

Enable/Disable frame drop

Set the Enable parameter on the switchif_frame_drop1 node to 0 to disable frame drop. When this is set to 1, the Frame parameter on the timeshift_frame_drop1 node ensures the even frame numbers are on hold, creating a cartoon-style look.

Change the size of the layer

Adjust the Iso parameter on the monotosdf node inside the copnet1 network.

Change the flame color

Adjust the Input Min/Max, Output Min/Max, and Ramp parameters on the monotorgb node inside the copnet1 network.
