PM texture problem

[sooon]

anybody getting the Projection master texture and colour problem??


i did some box modeling and use PM for the detailing. when i pm for displacement everything works fine but when it come to color and material, it just got distorted. even i project with color and material together with displacement, the displacement works fine but the colour and material just distorted into very bad shape. hmmm...

It's not just you, i've been trying to figure this out as well.

i thought perhaps the problem was with multiple uv sets, but this doesn't seem to solve it - i can delete the multiple sets on the original obj, then reimport it, and pm still give me these results.

i'm using uv's that stray beyond the normalized (0-1) tile...i wonder if this is a problem.

here's the image, before PM Pickup, and after.

Try this....while your tool or obj is loaded go to tools>textures and use the uvcheck to check for overlapping uv's. They will show up red on a newly created texture.

you could also save your tool with diff name and create a texture say at 1024x1024 and go to tools>texture>guvtiles go to PM and paint the face again and see if it does the same thing. am guessing it won't but who knows til ya try it.

so i tried the uv check - my entire model turns red...not quite sure if/what that means - i'll have to read through some more of the help.

thanks,

Hi guys,
I had this problem aswell, more than once.
Now,I'm not much of a UV-Tile/Mapping/Texturing expert, but I believe it had something to do with the memory of your computer.

Hope this will help to solve this problem, will keep an eye on this topic and hoping for a simple solution :p

so it looks to me as if i need to have my uv's from 0-1. then pm seems to work fine. does anyone know if there is a way to get pm to work with uv's that stray outside of the 0-1 range?

thanks,
sunit

Sunit,

I suppose you could simply dump the UVs you already have and then create new UVs using something like UVTiles within ZBrush. Then you should have no problems with overlapping UVs.

(PS - I admit that I did not read the entire thread, so I may be missing something here)

That's definitely a solution. i'm really just trying to figure out a good way to work between maya and zbrush. i reread the practical manual, and in meats meier's tutorial, he mentions keeping your uvs between 0-1, so i suppose that should be my current method. i was hoping to find out, though, if it is possible to work with uvs that are located in different quadrants...
