Control image seqnece as a texture

[reelinspirations]

Hi,

I'm needing to be able to tell an image sequence in a texture when to start.

Let's say my Houdini timeline is 3700 frames long, and I need an image sequence that's 100 frames long to start at frame 2,000 and run to 2,100 and then stop.

Is there any way to do this currently with Houdini and Octane?

So far, I haven't found a way to do this.

Any ideas on if this is possible?

Thanks,

Jim

Hi,

I'm fairly sure that you can build an expression to control the textures sequence with this behavior.

For example, if you use the next expression as texture filename:

$HIP/textures/texture-`padzero(4,clamp($F-2000,1,100))`.jpg

This expression should load as texture a 100 frames sequence of type "texture-0001.jpg", from the frame 2000 to the frame 2100, holding the first and last frames along the whole animation.

Hope this helps,
-Juanjo

That is brilliant, it worked.
I'm guessing I could use a ch("some parameter") to control the frames too so I can control when it fires at OBJ level.

I wasn't aware of those functions.
