Please check the MATPREVIEW_ messages in the documentation and the particlevolume.cpp and simplematerial.cpp SDK example files. These two plugin materials replace the the standard material with a custom preview scene.

}i tried colors and various parameter of material work fine...

one more question, is this a static background image or does it have to be updated by the material?

For just displaying an image it's probably easier to directly modify the displayed bitmap. You can do this in MATPREVIEW_GENERATE_IMAGE. Instead of rendering the preview document simply fill the preview bitmap. This will react to changes made in the AM too. Here is some example code:
Bool ParticleVolume::Message(GeListNode *node, LONG type, void *data) { switch (type) { case MATPREVIEW_GET_OBJECT_INFO: { MatPreviewObjectInfo* info = (MatPreviewObjectInfo* )data; info->bHandlePreview = TRUE; // own preview handling info->bNeedsOwnScene = TRUE; // we need our own entry in the preview scene cache info->bNoStandardScene = TRUE; // create our own preview scene info->lFlags = MATPREVIEW_FLAG_HIDE_SCENE_SETTINGS; // hide the scene settings entry return TRUE; } break; case MATPREVIEW_MODIFY_CACHE_SCENE: { return TRUE; } break; case MATPREVIEW_PREPARE_SCENE: { MatPreviewPrepareScene* preparescene = (MatPreviewPrepareScene* )data; AutoAlloc<AliasTrans> trans; if (!trans) return FALSE; if (!trans->Init(GetActiveDocument())) return FALSE; BaseMaterial* matclone = (BaseMaterial* )(Get()->GetClone(0, trans)); preparescene->pDoc->InsertMaterial(matclone); trans->Translate(TRUE); if (preparescene->pLink) preparescene->pLink->SetLink(matclone); preparescene->bScenePrepared = TRUE; return TRUE; } break; case MATPREVIEW_GENERATE_IMAGE: { MatPreviewGenerateImage* image = (MatPreviewGenerateImage* )data; if (image->pDoc) { if (!image->bEditorPreview) { AutoAlloc<BaseBitmap> bmp; if (!bmp || bmp->Init(Filename("C:\\test.jpg")) != IMAGE_OK) return FALSE; bmp->ScaleIt(image->pDest, 256, TRUE, TRUE); image->lResult = RAY_OK; } } return TRUE; } break; } return MaterialData::Message(node, type, data); }hope this helps
