Mudbox/Mari Tiled UV Textures

[vlado]

When you use tiles, you might have to manually adjust the min/max displacement bounds in the V-Ray displacement control extra attributes. When you use a single map, V-Ray can scan it and figure out the correct bounds, but for tiles V-Ray has no idea which tiles which be loaded and just assumes generic black/white bounds. In most cases you will need to override these manually.

@Robert, good test! Any luck with extracting vector displacement maps from multiple meshes at once?

@vlado, thanks for the explanation.

Thanks for the tip. I gave it a try this morning with my vector displacements and it did not seem to solve the issue completely. The displacement bounds did have an effect on the displacement (for the better) but they still were not displacing accurately. Once I set the white value past 1.5 it didn't really do much anymore.

No, currently Mudbox cannot do multiple meshes at once. It is just a current limitation. Hopefully that will get changed in a future version.

The MultimapExpoter of ZBrush outputting "u=0, v=0" as _u0_v0.

Is there any method of not doing "plus one" of <UVTILE>?

Thanx!

I was thinking it might be useful, but it's not yet implemented... I wish these guys settled on one way of doing it

Anyways, will make a note to add an option for this (probably lower case tag, e.g. <uvtile> instead of <UVTILE>).

Thank you for taking into note.

So this is now implemented for the next night build tomorrow; upper-case tags (<UVTILE>, $U and $V) work as before (1-based), whereas lower-case tags (<uvtile>, $u and $v) are zero-based. If you can test it and let me know if it works as expected, it will be very helpful.
