Thank you for this -- very enlightening!  I had no idea Canadians used the lavatory!

Very good! But I have one more.

I use "Blend" map for that in "Multiply" mode.

1. Replicate "Base Color" ("Diffuse") map
2. Make necessary changes to replicated map
3. Apply that map to "Blend" channel (make sure the "Blend Method" is "Multiply") and set "Strength" to 0
4. On the timeline, where change should occur, set "Base Color" ("Diffuse") "Strength" to 0 and "Blend" "Strength" to 100
5. Set transition curve to "Step" for the key.

Smooth transition is still not possible however, so the "Step" must be used.

I just wish the "Blend" channel would eventually provide a full support for 24 bit PNG files (for alpha channel particularly).
Then there would be endless possibilities for smooth transition adding all kind of "spotty" effects to the "Base Color" map without distorting it overall.

Nice alternative solution :D

Yes. This is what I would have done in the past too but I am trying to eliminate the need for re-processing as much as possible, so I came up with this technique.

I am wondering if you could the same tecnique on the bump and displasement channels for bullet holes and deep cuts

I have not tried it but by the title of the timeline track, I believe that this technique should be usable for any of the Texture Settings including Diffuse, Opacity, Bump, Specular, Glow, Reflection, Blend and Displacement.
The only down side of this technique is that if you are doing very subtle transformations the texture size can get very big (because you need many transition textures).

well actually any video even mp4 and WMV
and iClone 5 does it too

I do this another way
I save my textures as avi files using virtualdub and loop the first then the second
iClone will keyframe avi changes as in adding a new file along timeline

Thank you!
In the past I would have renderd two identical scenes (swaping out the textures in the second) and spliced them in my editor! this will save a consideral amout of time and I am wondering if you could the same tecnique on the bump and displasement channels for bullet holes and deep cuts

Saw this yesterday and meant to watch it last night but forgot about it.
Must must must remember to watch it tonight. I'm sure its going to help me with what I am currently working on

Edit
Changed my mind and watched it at lunch time. That's pretty obvious but not something I had thought about until now.
Thanks for demonstrating the method

@Lord Ashes : WOW!, that is a very clever idea. Thank you, 5 stars+

@Lord Ashes : Good find. Thank you for sharing
