Hi,

in my generator I have created some objects. Now I want to attach texture tags to those objects and link a material in those tags. The material is given by the user and linked in the description of my generator.

This is how I retrieve the material that the user has linked:

> BaseMaterial \*Mat = (BaseMaterial\* )bc->GetLink(MY_MAT_LINK, doc);

So far it works, "Mat" is not NULL.

Now I create a texture tag on an object in my virtual hierarchy and want to link the material there:

> if (Mat) { \> BaseTag \*MatTag = BaseTag::Alloc(Ttexture); \> if (MatTag) { \> MatTag->GetDataInstance()->SetLink(TEXTURETAG_MATERIAL, Mat); \> MatTag->GetDataInstance()->SetLong(TEXTURETAG_PROJECTION, TEXTURETAG_PROJECTION_FLAT); \> MatTag->GetDataInstance()->SetReal(TEXTURETAG_LENGTHX, MatScale); \> MatTag->GetDataInstance()->SetReal(TEXTURETAG_LENGTHY, MatScale); \> PolyPlane->InsertTag(MatTag); \> } \> } \>

I does not crash, but the material is also not linked. When I convert my generator object with "c" and look into the texture tag, the link field is empty. Why?

Thanks in advance for any help!

Cheers,
Jack

Oh wait. I just saw, there's a class TextureTag. Using its function SetMaterial(), I can successfully assign the material.

Anyway, I am not quite sure how to set the projection (attribute TEXTURETAG_PROJECTION) and the X/Y scale (TEXTURETAG_LENGTHX and TEXTURETAG_LENGTHY).

EDIT: Thanks, Samir. Didn't see that at first. But the projection and scaling would still be interesting to know.

Greetings,
Jack

OK, got that one, too:

I would like to have some more information in the SDK about which parameters of which objects/tags may be accessed via GetDataInstance() and which of them need GetParameter/SetParameter.

The question that remains is: How can I set the TEXTURETAG_ROTATION of the Texture Tag? In the .res file it uses CUSTOMGUI SUBDESCRIPTION, but I can't find any information about how to set the vector.

Cheers,
Jack

It's still a VECTOR type so you use GeData(Vector(x,y,z)); (or something similar).

dat = GeData(Vector(0,0,0));
MatTag->SetParameter(DescID(TEXTURETAG_ROTATION), dat, NULL);

CUSTOMGUI SUBDESCRIPTION simply describes the display interface for the type.

Aaah, ok :D Thank you!
I'll never stop learning (and that's a good thing).

Well, the first result of my last speed programming session (1.5 days) can be seen here:

I'll continue working on it from time to time.
