Render To Object Surface
Apply the field to the surface of geometry.
Render To Object Surface
Method #
The field is sampled spatially on to the surfaces of visible 3D objects. This is useful for generating fluid effects onto nearby surfaces, and because its volumetric, the generated effect can be applied to the UV map of the 3D object, and rendered out with the UV Camera.
The Render to Object Surface node should be parented to the Field Root node.
Deferred Rendering must be enabled in the Root node for this to function.
Parameters
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
Parameter Details
Position X Move along the local x-axis.
Position Y Move along the local y-axis.
Position Z Move along the local z-axis.
Rotation Heading Rotate around the local y-axis.
Rotation Pitch Rotate around the local x-axis.
Rotation Bank Rotate around the local z-axis.
Scale X Scale along the local x-axis.
Scale Y Scale along the local y-axis.
Scale Z Scale along the local z-axis.
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
Parameter Details
Position X Toggle inheritance of the X Position from the parent.
Position Y Toggle inheritance of the Y Position from the parent.
Position Z Toggle inheritance of the Z Position from the parent.
Rotation Heading Toggle inheritance of the Rotation Heading from the parent.
Rotation Pitch Toggle inheritance of the Rotation Pitch from the parent.
Rotation Bank Toggle inheritance of the Rotation Bank from the parent.
Scale X Toggle inheritance of the X Scale from the parent.
Scale Y Toggle inheritance of the Y Scale from the parent.
Scale Z Toggle inheritance of the Z Scale from the parent.
World Position Only Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit Time Toggle inheritance of time from the parent.
These properties control the core behaviours of the node.
Parameter Details
Alpha Changes the alpha of the field.
Brightness Changes the brightness of the field.
Visible Control whether the node is visible or not to the scene.
Sort Bias Biases the alpha sort in order to make it render in front or behind other transparent objects.
Velocity Alpha Scale The amount the velocity of the field is scaled when it is used to modulate alpha.
Blend Mode How the render blends with the objects original material colours. See Blend Modes for details.
- Solid : The field rendering entirely replcaes the original surfaces colour.
- Blend : The field rendering blends with the original surfaces colour, using the alpha channel.
- Additive : The field rendering adds onto the original surfaces colour.
- Subtractive : The field rendering subtracts from the original surfaces colour.
- Multiply : The field rendering multiplies with the original surfaces colour.
- Max : The max value between the field and the original surfaces colour.
- Min : The min value between the field and the original surfaces colour.
- Light : The field rendering is blended using the light blend mode with the original surfaces colour.
- Screen : The field rendering is blended using the screen blend mode with the original surfaces colour.
- Pre-Mul Blend : The field rendering mis premultiplied before blending with the original surfaces colour. Usually gives the best results for colour blending.
Use Field Alpha Channel Use the field alpha channel when blending with the original surface.
Velocity To Alpha Toggle whether the velocity amount is used to modulate the alpha value, so areas of faster movement are more visible.
