Caching and Write questions

[kepler]

Hi, I’m having some trouble figuring out the various caching methods inside Nuke. Here are my questions:

– How the “cache” option inside a node works? If I check it I cant notice any caching cause it does render again when I insert another node below…

– How the DiskCache node works? I hit the precache button and makes it’s “render” but if I insert nodes below it makes render again using the nodes above the DiskCache, like if it wasnt there!

– Why doing a write with read enabled reads the rendered sequence slower than if I use a Read node instead?

Thanks!

I think all the cache nodes are meant to be used when there are heavy nodes in your comp. if you have several very heavy nodes above the cache, you can cache just like your reading in a fresh sequence off disk. I like the disk cache node since it doesn’t ask where the footage is and just does it.

The write node having a read function is also very clever and can be used in the same way a disk cache node is used. (Although it doesn’t seem to work right with .exr’s
