Render Resolution and DS 4.6 Interface Questions

hjake

Why is it when I render an image at 7680x4320 and resize it to 1920x1080, it seems to have slightly more sharpness/detail than an image rendered at 1920x1080?

DS 4.6 with main distant light set to 150% intensity and Deep Shadow Map and 5 fill distance lights at 20% illumination diffuse only.

Using REYES (non-progressive render) and sinc pixel filter with a pixel width of 6.0

because the detail in the larger screen size takes into account the preciseness of the calculations that were necessary to make the larger image clear. The 1900xX render has a better opportunity to blur those calculations. Also the algorithm in the software that renders and the one that re-sizes don't necessary share the same method of arriving at the final product.

Thanks StratDragon that is very clear.

Greetings,
I like to think of this method of getting slightly better detail in images as 'manual 4x anti-aliasing'. :)

It relies a TON on having a good algorithm for resizing the image, though. Jack Tomalin put up a guide once which suggested rendering at twice-ish your final resolution, both for this reason and because post-work on a higher res image seems to integrate better when reduced back down.

Thanks for your comment cyberfox.

I took a look at your wishlist thingie. Nice work.

Back in the Mystery Mobile (aka my lugtop), more help please from any DAZ Geniuses out there.

I am using DS Pro x64 - 4.6.1.17

1. Besides using sort ascending and descending in the menu for the scene pane how can I rearrange the scene items so they are in groups (e.g. lights, camera, figures) I am interested in parenting them. I just would like to have items grouped together so it is easier to find them when my scene contains many elements. I have already tried numbering them, which works but is cumbersome.

2. When I am in the Pose/Shaping tab and I select "Texture Shaded" for the view port, my sky mapped sphere appears black, but when I choose Wired Shaded I can see the sky map texture.

Why is that happening and is there anything I can do about it?
