Hi;

In “Attribute From Map” SOP, I would like to load a range of frames as “Texture Map”.
I have 1000 frames, but and I want to load some of them (frame 400 to 600).
Is there any way to define a frame range, to load?

Thanks.

You could use:

sequence.`min(max($F,400),600)`.jpg

or you could create an img network, change the frame range in the file node and refer to it in your SOP.

Ok “Tanto”;

Do you mean:
E:/Render/Myfile_$F3.`min(max($F,400),600)`.jpg

?

Yes, that would do it, although doctorbob's “clamp” solution is more elegant. This will freeze frame 400 before and frame 600 after the sequence.

Edit: Wait no, it'd be 

ERender/Myfile_`min(max($F3,400),600)`.jpg
