<UDIM> <UVTILE> is used with the relative path will not work.

[flat]

If <UDIM>/<UVTILE> is used with the relative path (based on Maya project) will not work.

tested Maya 2012 64bits windows 7

[2011/Jun/8|15:17:05] V-Ray: V-Ray for Maya version 2.00.04 from Apr 28 2011, 02:33:53

In absolute path, it works fine.

[2011/Jun/8|15:23:05] V-Ray: Bitmap file "D:/testproj/sourceimages/color/blacksmith_color.<UDIM>.tif" loaded.
[2011/Jun/8|15:23:05] V-Ray: Bitmap file "D:/testproj/sourceimages/color/blacksmith_color.1029.tif" loaded.
[2011/Jun/8|15:23:07] V-Ray: Bitmap file "D:/testproj/sourceimages/color/blacksmith_color.1031.tif" loaded.
[2011/Jun/8|15:23:09] V-Ray: Bitmap file "D:/testproj/sourceimages/color/blacksmith_color.1032.tif" loaded.

Please check and fix.

Are you sure this is specific to tiled textures? Does it happen with regular ones?

Any textures occur.
It does not relate to a format.

I tested for the foundry site
http://www.thefoundry.co.uk/products/mari/training/
This DOWNLOAD contents.
http://thefoundry.s3.amazonaws.com/p...ithObjects.zip
http://thefoundry.s3.amazonaws.com/p...Textures_1.zip


Step by Step.
Project folder:C:\testproj\
Project source images folder: C:\testproj\sourceimages

1:file loader is set to Diffuse Color of VRayMtl.

2:The texture in a project folder (sourceimages/color/blacksmith_color.1001.tif) is opened from a file open dialog.

3:It is set to texture file path of Maya with a relative path.

4:The number of a texture is changed into like blacksmith_color.<UDIM>.tif.

5:hit render. no load texture.

But if absolute path is inputted manually, it will be perfectly loaded after it.

It's still downloading (and will be for the rest of the day it looks like ) so I can't check the scene yet. Works fine for me on a simple test though.

[EDIT] Looks like it works for regular textures, but indeed not when using the <UDIM> flag... looking into it now.

So this will be fixed for the next night build tomorrow.

Thanks so much!

One request.
If a <UDIM> <UVTILE> style texture is used, whenever it changes a material parameter, all the textures will be re-loaded and a swatch response will become slow.
If auto update of swatch is turned OFF, it will solve, but to have improved may be better.

[vlado]

That one will be tricky; for regular textures, V-Ray creates a low-resolution texture version for the swatches in advance (before the swatch is actually rendered). However with tiled textures, V-Ray doesn't know what textures will be needed in advance for the swatch... I guess for the moment it can assume that the first tile only is needed (for UV's between 0 and 1).
