My question is about switching shaders. I want an object to have three different shaders. For example, for frames 1-100 I want it to have a blue shader and for frames 101-200 I want it to have a green shader, then finally for frames 201-300 I want it to have a red shader. Now all three shaders must be seperate shaders (eventually they will be replaced with a clay shader, jelly shader, and another, different clay shader. I would like to figure out the concept first, of course).

The other thing is when one shader switches to the other, I want them to have a 30 frame blending period, so that they transition smoothly from one shader to the next. Now I have played with the switch SHOP, but that acts merely as a light switch, which will not give you a smooth transition between different shaders, or does it?

Any ideas of how to do such a thing?

well, you can either combine all three shaders into one and blend between them there, or why not just render the three version and blend between them in post.

I think you can also animate a Switch SHOP.

Simon-

How would you recommend "combine all three shaders into one and blend between them there"? Sorry, but I haven't really played around with the SHOP editor in too much detail.

I tried that, but the sliders on the Switch SHOP use whole numbers only, no numbers with decimals. Which makes the Switch SHOP a light switch.

Sorry, I didn't read your whole post. … If you want to do it in shaders, Mike Cronin has a great thread with examples here:

not really, keep plugging the inputs in and it will add more input fields. you can have many inputs

Very good! That thread answers all of my Q's!
