Offset animated texture map

[sly]

Hi,

I have loaded an animated texture/color map ( for exemple: 0 to 100.tif) , how i can offset it so that the animation begin only on some frames later . In the same way , how is it possible to keep the last frame holded?

Thank you.

Sylvain.

Reply to myself :

Load the file via cop/img with the file node , and there are some tools to modify the sequence

it's all about expressions in filename

if your path is

path/filename.0.tif - path/filename.100.tif

you can use `$F+offset`

path/filename.`$F-10`.tif

if your path is

path/filename.000.tif - path/filename.100.tif

you need to pad the frame number so if you want to offset it will be like

path/filename.`padzero(3, $F-10)`.tif

to hold last frame you can use min(offsetFrame, maximumFrameValue ) function

path/filename.`padzero(3, min($F-10,100) )`.tif

to hold first frame you can use max() function in the same way

to hold both ends you can use clamp(offsettedFrame, minimumFrameValue, maximumFrameValue)

path/filename.`padzero(3, clamp($F-10,0,100) )`.tif
