This node is used to compress a two channel floating point image – for example a UV remap image loaded in a floating point HDR format – into a 3-channel RGB or 4-channel RGBA 8 bit per channel output, which may make it suitable for storing in a number of standard image or video codecs.


Name Description
Blend Amount Changes the opacity of the new effect over the original image.
Mode Select how the UV animation is compressed – whether the result should use only the RGB channels of the output, or the alpha as well. Using RGBA provides higher quality but alpha may not be supported by all codecs and players.
Flip V Flip the V axis of the animation when compressing.
Quantisation The amount of quantisation applied to the incoming values. A higher level of quantisation may make the resultant image easier to compress and therefore smaller, at the cost of a loss of precision.


Name Description Typical Node Input
Active Turn the effect on or off. Values < 0.1 will turn the effect off, and deferred rendering must be on. Envelope Modifier
