Hi,

Had an idea about using an animated map on a material with motion blur. Doesn't work, it displays the current frame map across the whole duration of the motion blur. I presume because of some kind of motion blur optimisation. Any ideas?

It's not really a motion blur optimization, it's just that Maxwell does not support animated material parameters. Your host application will export different values for the parameters at each frame if they are animated, but Maxwell does not know about this and does not perform interpolation between parameter values inside a single frame. Doing this would be a pretty big change inside the engine.

Also, interpolating between texture samples may not give the results you expect, since it would be a simple color interpolation between texture A and B. You probably want some kind of morphing effect if the textures are very different, which is expensive, hard to do, and impossible to expose in such a way that it fits everybody's needs.

I think most engines have the same limitation.

Yea understood. It was asking a bit much and I will find a work around using geometry.

Thanks for taking the time to answer!
