Texture Dimensions Limit in Maya 2012?


#1

hey gals & guys!

i’m forced to work with an insanely high image-resolution as textures (can’t make any compromises there) and when loading a .tga with about 13,000 by 12,000 px i get an error simply stating that my file is too big. rendering with kill maya with a fatal error, doesn’t matter whether with maya software or mental ray. i even tried converting the texture to bop and map but i jut get the same error :frowning:

i wanna project the thing onto a mesh and bake a hi-res texture, that’s all…

any ideas? help would really be appreciated!

Maya’s limit is 10k, I have found no other solution

Not quite true, I’ve rendered 16k textures before. You might have to use the mentalray texture node however. And a tiled exr would be a much better idea then tga. Make sure you tick “local” in the mentalray texture node to indicate its a tiled exr which will activate texture caching.

that’s a good idea – will try! i keep you posted and many thanks!

alright, none of the above worked out, maya still snuffed it when i tried to render, even with a full mental ray setup and tweaked bsp. in the end i settled for a 81928192 file in 8-bit depth (which was the highest resolution maya would accept in my case) instead of the 1300013000 in 16-bit. gotta make this work in comp i guess. not happy, but at least a step in the right direction… :confused:

Did you try a 16384x16384 EXR though? I realize this is even larger, but texture resolutions are best handled when they are in a power of 2 resolution. And how much RAM do you have btw?


#7

As Corey mentioned, a tiled EXR would work well. imf_copy will make one for you with Maya 2012.

Out of curiosity, what resolution are you rendering at that you need a large texture like that?

@Kakkoii: yep, tried a regular exr, then tiled exr, then in powers of two… still maya whined about “texture too big”, not even command-line rendering would work…

i have 8 gigs of ram installed, running windows 7 x64… maybe that’s the bottleneck.

@Bitter: i’m rendering at full hd, but i need a highly detailed projection on a human head because the cam keeps zooming in to a pore-level. you can guess how much fun it was in photoshop stitching a 16-bit super-res from a couple of raw-photographs together… i guess i can thank the fickle & opinionated director for all that trouble :wink:


#9

i fear that wont help too much for you: vray renders that texture size without a problem :confused:

cheers

vray, eh? in fact that does help because now i know what to save up for next :wink: thanks!


#11

I just rendered a 16k tiled exr in Maya 2012 right now no problems. Your using the mentalray texture node, not the maya file node correct? And you ticked “local” on?


#12

that is correct! the only maya node i used was the projection node because i couldn’t find a mental ray equivalent. the problem is that when i open the scene, my script editor already reads “<texture-path and file name> too big” and rendering will plunge it all into a Fatal Error purgatory… sucks…

and thanks for keeping up your suggestions
