Hello everyone.
I am playing with volume slices. It works well. Now what I would like to do, is to animate the volume by changing the texture for the volume at every frame. The volume slices setup uses “Texture Object” as an input. My first guess was to use “Static Bool” with “Switch” to change them (static_bool_parameter.jpg). But, even if the parameters were showing up into the Instanced Material, it did not appear into the sequencer under the “Material 0” parameter. If there is a way to control it via the sequencer, I did not find it.
Then I tried to make a Material Function of the set up and repeat it for every images (material_function.jpg). It works. But, it is messy, probably quite expensive, and it makes it a long process to setup.
I was wondering, there must be a better way to switch those Texture Object? A single node that takes all the input and output the right one a the right time would be perfect, but there is no such thing as perfect. Anything easier would be awesome. It can be blueprint, but I am still a rookie with BP, so please, be descriptive. 
Thanks.
