2D Displacement with UV tiles problem

[AJ Jefferies]

I'm 99% sure I've seen this problem documented already but I've done some searching and couldn't find anything so thought I'd start a thread just in case.

When working with displacement on an object that has UVs spread across a number of tiles, my current workflow is to use composite textures & the offset value to create one 'map' for the displacement. This works really well with 3D and Subdivision displacment, however when using 2D (which is usually much nicer/tighter) it will only use the tile at 0,0.









I'm sure there's a logical reason for this (my naive thoughts say it might have something to do with difficulty in gauging the resolution of the full composite map?) but it would be fantastic if it could work the same way.

This won't work with 2D displacement, as it specifically assumes that the displacement texture is valid only in the first UV tile.

Vlado is there a support for udim/uvtile tags in max like we have in maya?

Not yet, although we can easily add it to the VRayHDRI texture - I will make a note to look into it.

Hi Vlado, thanks for this. Just to 100% confirm, it will never be possible to use this method of mapping with 2d displacement?

Well, for the moment you could probably set it up manually with a few different displacement modifiers for each texture where each modifier is applied only to the respective faces, but it can be quite complicated to set up.

Ok - thanks!

I've done similar thing a long time ago, where I wanted to use 2d displacement on multi tiled character, and had to split the geometry up, and do unify normals around edges to ensure they looked part of one mesh.
