RPR Material Nodes lack the option to use Image Sequences as a changing mask over time.

e.g. If you use Blenders Dynamic Paint feature to export a black and white Wet Map for an animation this can usually be used to mask the area that will become the wet part of the material. (see this YouTube for a full example Creating Realistic Wetmaps in Blender CGC Weekly #20 - YouTube​ )

Similarly if using the excellent Adobe Character app to generate a transparent PNG sequence of a lip sync you cannot render the "Image Sequence" over a material applied to an animated character face when using RPR in Blender.

Feature request: Image Sequence input node for materials.

Same need ! +1

Hi all here.  Being a lazy developer, can someone attach a scene/textures of this in cycles so I can create this easier?

Very basic Lip Sync setup in Cycles attached.

All files included in the Zip. The assets folder is required as it contains the image sequence and Blender won't embed all of those files into a package.

Hope it helps.

There's an audio file and an rendered out MP4 video of what Cycles makes. Scene lighting and setup was done in a rush!!

It's also important to see the Cycles node setup for the material with the Image Sequence. It has to support alpha from the PNG files so that the images are placed on top of an existing material using a mix shader.

The setup is usaully done with a additional UV mask and the Image Texture is set to align to this.

The ability to set which frame the sequence begins on is pretty essential for animation timing.
