| Problem with 3DXI Export UV
|
|
|
I want to export uv info from a model.I added only one texture in diffuse color map in my model.
set uv in channel 1.
my code like this:
/////////////////////for block,loop by face index i,and face coner y/////
int Texindex = gM->GetFaceTextureVertex(i,y)
//if(false == gM->GetMapVertex(1,Texindex,tempuv))
if(false == gM->GetTexVertex (Texindex,tempuv))
{
char str[256];
sprintf(str,"The node %s UV %d failed!!",nodname,i)
MessageBox(GetActiveWindow(),str, "MyExp", MB_OK)
}
texV[i*3+y].u = tempuv.x;
texV[i*3+y].v = tempuv.y;
/////////////////////////end for/////////////////////////////////////
/////////////////another for block,loop as preceding////////////////////
fc3d[i].tvertindex[j]=static_cast<WORD>(i*3+j)
/////////////////end for////////////////////////////////////////////////
But it just give me the wrong answer.
Any one knows why?
Thanks for you attention.

And I also tried this:
//Build UV array
for(i = 0;i<IGmesh->GetNumberOfTexVerts()i++)
MyuvArray[i] = GetTexVertex(i)
//Access by FaceEx.texCoord
MyfaceArray[FcInd].UV[conerindex] = curr_FaceEx.texCoord[conerindex];
but get the same result.just the same as above(The picture of dirty one).

File size? 3.5MB limit per post.
Different browser? Had one or two people using Safari unable to attach anything - try Firefox, works fine for me.
Worst case - upload it elsewhere (YouSendIt or similar) and post a link, though this is not the preferred method and should be considered a “last resort”.

Thank you.
It just 1188KB rar file.
Now ,I found the causation of this issue(the uv problem).
It because,in MAX ,the model’s UV origin in left-bottom corner.
In my GameEditor(use d3d9),it’s UV origin is in Left-Top corner.
Is there Any function in sdk Could test the UV origin states?Or set it in max?

Helps if you actually READ the replies. This site does not accept .rar attachments. You MUST zip it.
I can’t help directly with SDK issues - sorry. Normally a lot more folks here during the week (weekends a very quiet) - you’ll hopefully get some replies then.

Oh, It’s my fault,I miss the word ‘not’.......haha.
I think, This UV problem should not be SDK’s fault.I just wonder if there are any method in sdk could let me know which UV-coordinate being used.

Okay, I don’t really know this section of the SDK, but have you tried using 0 as your channel? I would assume that what is listed as channel 1 in the UI would be programmatically accessible as channel 0, due to convention. If this doesn’t work, I can’t help further, sorry.

He’s already fixed the problem—the UV coordinate system is different in Max to DirectX. The mapping channel was correct.
marzoner, there need not be a ‘method’ in the SDK to tell you this, as it’s not state that changes, but rather a convention. This is something that is (or should be) in the docs.
