Hello,
Thank you for your question.
It won't be necessary to blend the two images together using the BLEND_FUNC, this is what is causing the image to only show on the darker sections of the back ground image.
You can simply place one image on top of the other so long as the image has an appropriately transparent background, for example the below code places an ASTC image (motorbike) on top of background image:
BITMAP_HANDLE(0)
CMD_SETBITMAP(0, RGB565, 800, 480)
BEGIN(BITMAPS)
VERTEX2F(0, 0)
END()
BITMAP_HANDLE(1)
CMD_SETBITMAP(768000, COMPRESSED_RGBA_ASTC_4x4_KHR, 288, 164)
BEGIN(BITMAPS)
VERTEX2F(6112, 4208)
END()
Please see the attached .png for an example of the above code running in EVE Screen Editor.
