I have been trying out Daz 4.7. 

If I just load a figure , say Genesis 2, with the as installed settings and one of the lighting presets, the render to screen produces a background of grey and white  squares, which I normally associate with a transparency in Photoshop. However when  I save this render and load it into Photoshop the background is black. It would be really nice to  retain a transparent background,  but failing this a white or pastel colour would be acceptable. The colour  of the background in the view port does not appear to influence on the outcome.  Can anybody help with this problem?

 What type are you saving the image as, jpg doesn't give a transparent background you need to save as png or tiff.

Thanks tparo. The png worked but the tiff did not.

I should have thought this one out myself. I think it was the black that threw me. If it had been white I might have realised  what was happening.

Oddly, the tiff produced a black background with a halo around the figure, but the miniature icon that DAZ always produces did have a transparent background.

Anyway, thanks for your help

TIFF works for me in Paint Shop Pro.

In Photoshop tiff loads with a black background, but there's an alpha channel you can use to select the rendered parts and the colour bleed into the background makes sure there's no haloing once the selection is floated.

I had fun and games getting a background image into the render  Why did they change how it is done radioham

A pane is more accessible than a dialogue box, and I think it was implied that additional features are planned which required the use of a pane.

It may have been implied  I never seen that...  but they never to date released a guide  to tell users what the new 4.7 can do  and where to find the new parts.. like to add a backdrop  you have to open a pane  then do two things to get to your backdrops  how many have found that out by guess work    radioham

This is a new thing, previous updates have relied on the announcement thread in the forums.

Hello Many thanks for the help  will have a good read at it...
