Shake 2.5 file format that contains z channel????

[beaker]

Plugins are installed in the same place as scripts. I'm guessing you just can't install plugins that have installers.

Download and install the shake 2.5 exr reader/writer plugin:

Oh, also, shake 2.5 should be able to read 32 bit tiff files. Only trouble is you might need to change the tiff compression type that renderman uses by default (zip I believe, which shake 2.5 doesn't have support for). Open the renderman.ini file and look for the line with "tiff" in it and change it to something like "rle" or "none".

shake 2.5 reads .rla and .iff files, no plug in needed. (so maybe you can render out iff in maya software if renderman doesn't render them out)
here is a tutorial for that getting the z channel to work.

i am currently struggling with getting the z channel to get working.
cannot figure out how to blur it though (since i just opened shake yesterday for the first time).
if you figure it out, would you mind posting it?
thanks.

cannot figure out how to blur it though (since i just opened shake yesterday for the first time).In the blur node at the bottom of the parameter window it says "channels" and by default it is set to "rgba". Just change it to "z".

thank you so much for answering!.
i still have a problem due to my lack of skills with shake.
...not sure where the blur node should be plugged into:
here is the node layout i got so far...

thanks again.

Doesn't really matter where you plug it. Just put it after the copy node.

[neurobasics]

still not working.
i have tried plugging in the blur in various places, i have changed the channels on it, i have used the tutorial files from the link and still i cannot control the blur depending on depth.
thanks for your help...
:(
have tried to do the same thing in after effects and i get stopped at the same spot: i see the depth. i can't control the blur depending on the value of grey.
is it possible that there is a certain script for shake that helps to interpret and control the blur of depth in iff or rla files from maya?
sorry to be such a pain.
thanks again for your help.

Select all your nodes from this operation in Shake and do a "Ctrl C" copy and then "Ctrl V" Paste it into a post in this thread. Shake copies the ascii text from the nodes when you do this.

SFileIn1 = SFileIn("//Sovva/C/Documents and Settings/Luba/Desktop/zCompExample.iff",
"Auto", 0, 0, "v1.0", "0");
IRetime(SFileIn1, 0, autoInPoint, 1e+007, "Freeze", "Freeze");
Blur1 = Blur(SFileIn1, 94.4, 60, 0, "gauss", xFilter, "z");
Bytes1 = Bytes(SFileIn1, 4);
Reorder1 = Reorder(Bytes1, "zzzz");
Mult1 = Mult(Reorder1, -4, red, red, 1, 1);
Reorder2 = Reorder(Mult1, "rrrrr");
Copy1 = Copy(Blur1, Reorder2, 1, "z");

interesting, the idea of shake is quite similar to maya.
or the other way around.

thank you (agian and again and again)/

I got it now.

When you said:
i am currently struggling with getting the z channel to get working.
cannot figure out how to blur it though (since i just opened shake yesterday for the first time). I misunderstood. I thought you wanted to blur the actual z channel, not blur the image "based" on the z channel. Two separate things. :)

Simple answer. Use the "Zblur" or "Zdefocus" nodes in the "Filter" menu.

Also Fredrik has a link to this tutorial at the bottom of that z depth page. It has a mini shake tutorial on bluring based on a z image(or any grayscale image).
http://homepage.mac.com/bauer/portfolio_shaders/zDepthDOF/zDepthDOF.html

Also there are a few macros on highend that do this too.

[neurobasics]

it works!
thanks.
you were right about the blur. i just should have used IBlur and not the Blur filter.
..figured out after going through the tutorial...
(plugged both reorder and copy into the iblur for final output control).
thank you for such dedicated help i really do appreciate it and for info on the tutorial.
phew..

[beaker]

Check the zblur. It gives better results and more control over the final results then an iblur.

[neurobasics]

oh yes!
i wish i could express my excitement using qwerty.
zblur is amazing and it does give more control,
magnificent.
here are some quick test images (don't mind the bad shadows and all, but the z depth is working!):

thanks beaker.
you helped me out so much.
