translate uvmap from UV pos to another in 3dsmax?

NAIMA

Hello , does someone knows how can I translate textures from an UDIM position to the other without loosing the precision positioning in the UVmap texture ? so imagine if I did a baking of several UDIM textures and now I want to translate them all into central first uvmap textures without loosing orientation ,position and all .

Use the transform input fields at the bottom of the UV editor

Eg. Type -1 in the X field to move them one tile left

UVWXform modifier?

Can you show me how to ? Because when I go there its not selectable and unresponsive .

Grab the UV shell(s), to be safe do this in polygon with select element mode enabled (next to polygon button at the bottom left), press w, then type in 1 (or -1 if you want it to in the other direction) down here.

Thankyou , pressing W worked, is there als a way to scale up ? For example I used 50% snap when scaling but for some reason they use a different origin and so they do not end up in a precise position , to explain better I have arranged pieces of the textures in an array in one single textur uv space, but I want to scale them up so that each piece will fit into a specific uv space , not sure if I explained well?

I think it'll always scale from its origin, which is defaulting to the averaged center of the uv shell. There may be a way to grab that origin and snap it to a vert or location so it'd scale properly to what you'd need, I'm not too sure

When I scale its always misaligned, I used a custom texture with the custom uv tiling to take measures in the single UV map then I scaled to what should have been rightfull positions with a snap % but it doesnt and it seems missing the positioning with precision offsets.

If you want a shell to fill the UV square, use the Pack tool, then move it back to the UDIM you want.
