I don't know why, but the err parameter in InitBakeTexture(...) is BAKE_TEX_ERR_WRONG_BITMAP, after call the function.

I'm really confused, because InitBakeTexture() does not handle a bitmap as parameter... so why it says wrong bitmap??

And BakeTexture(...) returns BAKE_TEX_ERR_NO_DOC. I have two BaseDocuments, one is doc, is the main document in the plugin:

virtual Bool SequentialBaking::Execute(BaseDocument *doc)

And the other is created only for the baking process, bakeDoc:

BaseDocument* bakeDoc = BaseDocument::Alloc();

My calls to bake texture:

---------------------------------------------------------

bakeDoc = InitBakeTexture((BaseDocument* )doc, (TextureTag* )textag, (UVWTag* )uvwtag, NULL, bakeSettings, &error3, NULL);

// error3 = BAKE_TEX_ERR_WRONG_BITMAP

// BaseBitmap:
BaseBitmap* resultbitmap = BaseBitmap::Alloc();

error = BakeTexture((BaseDocument* )bakeDoc, NULL, resultbitmap, NULL,NULL,NULL);

//error = BAKE_TEX_ERR_NO_DOC

// and of course resultbitmap->Save returns NULL...

-------------------------------------------------------

I'm really confused... Anyone knows how to make it work?? I only want to save the baked textures in a folder, with the name of the baked object...

Thanks for the help.

Cheers

It seems that the BAKE_TEX_AUTO_xxx IDs are causing the errors. It's not quite clear to me how to use them either. I will ask the developers.

Using a fixed texture size seems to work fine though (BAKE_TEX_WIDTH, BAKE_TEX_HEIGHT).

cheers,
Matthias

Ok thanks Matthias, I will try using a fixed size, would be great to view autosize working...

I will post the results.

Same errors using a fixed 1024x1024 size...

Modifing the code like your example works (YES, THANK YOU!), but only if I use a fixed bitmap size.

Can you give a working autosize example please??

Thank you again for your help, Matthias

Sorry for resurrecting this old thread. But I can't get the example Matthias posted to work.
The error I get is: no instance of overloaded function "InitBakeTexture" matches the argument list

I'm puzzled why it's asking me to overload a method. Because there is never one used in any of the above examples.
And when I try to make one inside of my class. I can't get it to compile.

Did something change between then and now that's making this not work anymore?

Hi,

The compiler doesn't tell you to overload InitBakeTexture (). InitBakeTexture() has 2 overloads (2 versions of the function but with different arguments) and it just can't find which overload to call.

Instead of declaring error as LONG:

LONG error;

Declare it as BAKE_TEX_ERR:

BAKE_TEX_ERR error;

And it compiles fine now - yes just that... poor compilers :).

I've just looked in the SDK docs up to R13 and the error parameter is given as a LONG. So this looks like a documentation error. Can't really blame the compiler for that

(Looking in c4d_tools.h shows that InitBakeTexture does use BAKE_TEX_ERR but this change hasn't made it into the docs.)

Right. The parameter type is wrong in the docs. So... blame the docs .
Thanks for pointing that out Steve.

Works fine now with the correct type.
