Can Poser 2010 save as a Photoshop PSD file?

I know Poser 9 / Pro 2012 certainly does... if you have Photoshop, this is a good option... certainly if you render z-depth maps etc. along with your main render image.

Although... I have occassionaly noticed some bugginess there (artifacts appearing in the Photoshop export).

You can export as jpeg with the quality set to 100% too. But that is still lossy... technically.

Although, you might be hard pressed to see the lossiness, unless you're rendering at a very high resolution.

I think the PSD export option is probably just equivalent to saving as BMP or TIFF? But it is layered...
