Hi guys

Not sure if this has been covered

But here is render,which I've done just,I've tried to set filtering to Crisp or Quality etc plus tried almost everything,but still is not crisp as should or what I've seen what people posted over here 

http://www.renderosity.com/mod/forumpro/?thread_id=2877297&page_number=2

Picture on Envsphere is 2048X2048 and is HDR

Is this limitation of EnvSphere or my HDR picture is just too small ?

Render settings are usual: Pixel samples are 6 and Filter is Sinc 3

Thanks for any help guys,Jura

And here is HDRVFX Pond picture which you can find in Poser Pro 

And test render with free sIBL Desert_Highway

As you can see nice crisp contours of the HDR on the ball with chrome material,but not on the EnvSphere

To see picture larger please open the image in new tab(Right click on the mouse and click Open image in new tab)

Thanks,Jura

The number of image pixels you "see" with your Poser camera will determine whether it is sharp or blurry.

There are two factors that affect this: your camera focal length, and the pixel size of the panoramic image.

2K is so low that you can only use a very low focal length.

Note that traditionally these images are ONLY for lighting and something to reflect, not to look at.

It is common to place a normal image in front of the camera to look at, mounted on a one-sided square. Since this image only exists where you're looking, it can be rather small while still appearing to have high resolution.

Hi BB

Thanks for reply,really appreciated.

I usually using 25mm or 35mm,75mm focal length I've not used for while,unless I'm doing something like Portrait

And thanks for clarifying about the using single sided primitive,this has been mine misconception or misunderstanding about the using of EnvSphere as background and for lighting too...

On first render I've used 2k probe and tried to use too spherical map(this has have above 4k),but with same results with blurry render... 

What is good size for probe or spherical map if I can ask?

In 3ds max those probes or spherical maps working fine and never have issue with them..

Again thanks for reply,really appreciated

Thanks,Jura
