headus 3D tools

Hello, I just downloaded the professional tryout version of Headus, and I was trying to export a intricately sculpted fish obj from Mudbox. The poly count is about 420 thousand, the mesh looked super dense in Headus and is lagging quite a bit. Is my poly count too high? To cut down polys I could export it to Maya and trim the unnecessary part while preserving the details, I'd just like to know what poly limit should I be aiming at. Thanks.

Yes, sorry, 420k is well over the limit. Not that there's a hard limit as such, its just that things will run very slowly as you go higher and higher. Typically you do the UVs *before* subdividing in mudbox though.

I found this ...

... which suggest you probably can still load the lo-rez mesh into UVLayout, create the UVs, then copy those over to your already sculpted hi-rez mesh.

Wow thanks phil, you attend to every question on here it's amazing. I'm gonna try exporting my base mesh out, I didn't know I'm supposed to UV map first before I sculpted away, now I know.

Sorry for bringing this one back to life, but for a project Im working on, I have some very dense meshes which already have uvs, but I need UV layout's awesome packing tools. The problem is that im not able to load the meshes, UV Layout throws an error (see attached images).

I dont want to cut or weld, only repack the shells (using the "Fit To Sqr" option). Also please notice that I don't have to the low res versions of these objects, so there's no such thing as "base resolution" this time (I know, I know.... is not a good idea, but that's what Ive got)

Is there a workaround for this? Or any idea to make it work?

Thanks in advance,

Orlando.

"only repack the shells (using the "Fit To Sqr" option)."

So would I be correct in thinking then that you want each shell to stay in the current tile during packing? If yes, then you could split your mesh up into smaller pieces so that you're only loading one tile at a time into UVLayout for processing.

The only other alternative would be to load UVLayout onto a 64bit Linux system ... there's a 64bit Linux installer on the uvlayout.com Support Extras page. It all might run really slowly still, but on the 64bit system you wont hit the memory limits that the 32bit systems have. And no, sorry, there's no 64bit Windows installer available at the moment.

Thanks for your answer Phil,

Unfortunately I cant split the mesh (Im not allowed to do it), but the linux version sounds like it's worth a try. Last time I checked you could use only network license on linux because there were no drivers for the dongle (or something like that)... So one more question: Is it possible to use a dongle in linux?

Too bad there is no 64 bits version for Windows, but i can perfectly understand it: this is the first time Im in the need of it because of memory limits.

Regards,
Orlando.

Yep, your dongles should work now with the 64bit Linux builds.
