Effector changing textures

Hello

I’m looking for a recipe to have a multishader with a series of bitmap textures on a clones be replaced by other bitmap images in either a “hard cut” or a “cross fade” as an effector falloff enters the cloner’s area.

Is there a way to do something like that?

Thanks!

Hi Alex,

You could just use a MoGraph Color Shader as a Layer-Mask between two Multi Shaders. (Typical set up problem, to forget that the MoGraph Cloner is set to white, it should be: Transform> Color> black)

Besides that, there are many ways to change the content, as images from the MultiShader can be also directed with Selections, Weight, and other options, but each needs a certain set up. IF I would more know about the specific target, I might can share another set up, just in case the one above isn’t working for you.

All the best

Thanks Sassi, that’s a great approach…

I basically have a large architectural surface made of individual tiles.  I want to assign a series of bitmaps to the tiles, and then use the falloff from an effector to switch from one a set of images to another.  I think the approach you recommended would work quite well, but I’d be curious to know how this would work with selections for example?

Thanks!

Thanks for the feedback, Alex.

The Selection would work in the way demonstrated below

I used the P.Y here to illustrate the process, check off the Position once it is set.

In a nutshell, the ones that should change are in each MoGraph Selection Tag, and if a change is needed, the next MG Selection Tag get pulled into the Selection field, a keyframe is set and off to the next.
Each selection tag has a complete situation stored and can be used again at any time.

Besides that, you mentioned cross fade, that would need a little bit XPresso. Just to mix from one selection (A) to the next (B) and when this is done (100% B), then swap A out and place C into the mix and got back, etc.

All the best

P.S.: Blend MoGraph Selections
