Archimap UV with pixel gap?

Coding Python Support
1

When baking shadowmap i unwarped with Archimap UV occured an artifact when the uv island is very near i think need 2 pixels gap between uv islands to avoid this.
I try the autouv_z3r0_mesh4.py it have pixel gap feature

http://www.filefactory.com/file/29d821/

it works well for blender (linux) 2.41 but in 2.42 RC2 not!
I would like to use it in 2.42 RC2 with multi UV set and i cant use 2.41 because it
not backward copatibility with multi UV set and delete all multi UV set info :frowning:

it have an error on 2.42 rc2 linux (ubuntu 32 drapper drake) with auto uv script:

Traceback (most recent call last):
File “autouv_z3r0_mesh4.py”, line 56, in ?
File “/usr/lib/python2.4/random.py”, line 68, in ?
import _random
ImportError: /usr/lib/python2.4/lib-dynload/_random.so: undefined symbol: _PyArg_NoKeywords

But the AcrhimapUV.py works well just missig this (pixel gap) feaure that may very useful this for me and assumed for others too.
Somebody can help with this problem z3r0_d or ideasman42 ? :slight_smile:

can u post here the script because im on linux and I cant install the windows version (because rc3 only release for win and mac yet)

4

try rc2 then, the script may not run in 2.42

5

yes i try the 2.43 RC2 yet it is use the old 2.41 ArchimapUV it have not island margin option only have the old one Bleed Margin option :confused: (i think it is a static install vesion and for this using the old scripts form script library)

Try RC3 and do a standard unwrap while in UV Face Select. The menu pops up and offers the new ‘Unwrap (smart projections)’. The feature is hard coded into blender now. Do: F, U, then at the bottom of the list select.

I think this is what you’re looking for. The features are nearly identical to Archimap and work as stated above with the ‘Island Margin’ as an option.

RC3? for linux :eek: where can i found it?

the simple unwarp not right for me because it consume lot of space and it havent space gap beatween uv islands but with Archimap u can set less place and if its ture the new version this script have an new option Island margin i hope this is not same as with Bleed margin .

gap beatween uv islands(only work !! autouv_z3r0_mesh4.py script in 2.41):

yes no linux yet but this is a good news if its true :slight_smile:

12

yeah, its accessed from the UKey now, as it should have been.
I never liked the name “archimap”, but smart projections sounds a bit wanky too :confused: and the old name kinda stuck… anyhow. thats there it is.
rc2 is very good… This is way more RC’s then we useually do so dont worry about using a non release blender…

i hope somebody will compiling the linux rc3 release soon and i can try this new feature :slight_smile:

thanks for helps
