I figured I would ask, instead of keeping trying to change my angle of view of my monitor…

If I have a character in poser and render, looks good.

Open the PZ3 in Carrara, and render…looks good, but the render is blurrier.  Is there a render setting to make it more crisp?  My first guess was filter shaprness…but that did nothing.  I set object accuracy to 0.5 and antialiasing to good…still nope.

Hmm, can you add the render so we can see what you’re referring to?

Is it an animation or still image? Are you using a compressor?

OK, so my lighting in Carrara leaves a little to be desired right now, and I had to reset the face morph, so I lost the expression…but I think this and the next post give you the idea.  I tried to make the scenes similar

This is Poser

Global Illumination always looks “soft” in my opinion, because it tends to reduce contrast.

AA to Best will look slightly sharper, but at a render time cost

Set your ambient light to 0… Always… That is the biggest contrast killer.

*some shader suggestions:
add a light brown translucency to the hair shader, and a neutral grey translucency to the tank top - will help them both look more touchable and less like “hard clay”.

GI also tends to null out your highlights, so don’t be afraid to push highlights on select shaders in your scene, like the metals and the wet parts of her eyes…
Try putting a VALUE=0-1000 shader in the highlight channel set in the 200 range, control the size of the highlight with the shininess shader (higher values make the highlight sharper/smaller)

So is the Poser render using GI, because it looks like the Carrara render is using it, or at least the Skylight. It might also help to know what compression settings you’re using. I also am wondering what your resolution is set to in the Render room? It defaults to 72 dpi which is fine in most cases. I wouldn’t lower it, unless you’re doing test renders with GI, because it will look fuzzy.

OK, I switched carrara to a 3 point light setup, with no GI, still trying things, just read Holly’s tips…not sure how to get a soft light yet.

You mean for soft shadows?

For her skin, check the tutorial at the link in my sig for “Creating Specular Skin Effects”...
If you have a specularity map you can substitute the Cellular shader in my tutorial with the spec map

Yep, for soft shadows.  Its at default 72dpi.  Trying your specular thing now holly.

Something crazy goin on with the eyes, but followed a couple other suggestions.

Is it just me, or is it still blurrier?

Lookin good to me… Maybe I am not sure what you mean by “blurry”.

Sometimes I render at a much higher (double) res, to PNG, then make my JPGs reduced in Photoshop…

Well, your Poser Image had entirely different light positioning and shadow settings - rather than blur, I think the sharpness comes from the sharp contrast that your Carrara lighting isn’t mimicking. I haven’t read everybody’s posts above, but:
Be sure you don’t have any lights from Poser in your scene. If any came with the import, delete them.
That stark white (or very light) shadow caster in your Poser scene is a key element to what you seem to be looking for - so place a spot or distant light (just one light for now), and get that aimed properly to get the effect you want. But for now, try to match what you did in Poser. I know that working with lights in Carrara is altogether better… I mean… different than Poser, so you’ll just have to use the image for directing you towards the proper angle. This is where a Distant light will simplify your task. I like using Sopt lights because they give me the extra control of distance falloff, which I use constantly.
Next go for subtle highlights, either using a lot less shadow intensity or none at all, using your Poser image as a reference.

I really like what you’ve done in both Poser and Carrara. I actually like the Carrara shots better, except when I’m looking for that stark contrast shown in the first (Poser) image. No doubt… Poser can produce a beautiful render. Carrara should be able to beat it - especially in speed. I believe that one of the default Poser lights is subtractive - which C8 and higher have the ability to produce as well. So if you want to experiment….

Cool shot. I hope you find this helpful.
