When writing Textures to BMP from the Renderer through DX9Texture or directly from FileTexture with “writer (Texture)”, there seems to be an error with the alpha channel.
Even though alpha is 100% in the texture, alpha=0% is written to the bmp-file (analyzed with photoshop).
Seems to be hardware-related. My graphics card is Nvidia-Optimus. This does not happen when I switch to the internal card.
VVVV beta 33.3 (x86)
Geforce GT 640M LE (Optimus)
is this a vvvv bug or a directx bug or a nvidia driver bug?
