Maya crash

[meera41]

I am using maya 2011. Evrything works fine.
Bt as soon as i load a .tif texture it crashes.
Other format do work, but i have already baked all of my maps in this format, nd they r just 2k.
Even if i do use other format, i wanna know why this isnt working.
I have my tiffFloatRender plugin turned on, bt still it doesnt work.
any suggestions guys?

Its weird behavior from Maya, anyway try changing the compression as well as other settings while saving the tiff file in photoshop.

[meera41]

any major differences between .tif and .tiff ?
sry for silly question

[omkarjere]

I don't know actually( not into texturing and photoshop) but use I mostly see .tiff used.

Hi Meera,

There is a well known issue of tiff usage inside Maya especially when you are rendering with mental ray and you are using tiff as displacement map.
So first of all can I ask for what map purpose are you using tiff?
Secondly, are you getting this error message:-
MG 0.0 error 101003: //my.tif: file format subtype or version not supported

As far as .tiff and .tif are concerned I thnk .tif is an Adobe proprietary file format. Google it you might find better answers.

So the conclusion is if you are using .tiff file format inside Maya as a displacement map then you need to convert that grayscale image into the RGB colour-space inside the phhotoshop by going inside the mode option. While saving make sure you do not use any compression because Maya will crash.
Lemme know if that helps.

Yes i am using it for Displacement Map, it is in RGB mode and no compression either.

First it gives me this error
"TIFFReadDirectory: Warning, foo: unknown field with tag 37724 (0x935c) encountered."

A second later it crashes before u cud read tht.

And same thing for PSD format too, but it doesnt crash, it just says " Error: (Mayatomr.Output) : while defining texture "fileHeadDisp:tex": failed to open texture"

Does this have anything to do with 16bits/Channel?

Try an 8-bit version

I think using 8 bit might cause loss in the 16 bit gray-scale information.

Ummm well the first error message goes off while using the RGB 16 bit/channel tiff images. As far as second error message is concerned it looks like a "Read Error" prompted by the Mental Ray plugin which is not able to open the texture.
Now this can happen because either your texture got corrupted due to the crash or the tiff file you saved is on a disk that requires elevated permission to access it. If this is the case can you check if the same texture file can be opened inside the Photoshop or not?

Checked
Checked and
Checked
Unfortunately that didnt work either.
Maya officially hates me.

I am using Jpeg now tht seems to work fine (till now)

Thank you for taking ur time for try solving this guys

[semiprowolverine]

Poor softwares cannot hate anyone they are the by product of what is usually known as "Garbage in and garbage out" or in other words some bugs which are not handled properly. There are lot of posts about your issue on the web if you try to google it, but that doesn't make sense since you are using a different file format.
I am not a texturing and modelling guy however in my opinion Jpegs are a bit limited in the way they store information and compress it. I would suggest- if you have a nice disk space-to switch to OPEN EXR or else you can use targa as the file format. I hope that makes sense.
