Max can't render too small image?

[SamSed]

why not just resizing it in photoshop ?

[jonestation]

Samsed, thanks for prompt feedback and suggestion. I tried before, it get blur.

[SamSed]

ok , i just tried that with max , i can't say it's blury or not because it's too small :eek:.if you are using a camera maybe you have to check out if there's DOF or motion blur applied .check out your renderer setting too.

[jonestation]

OK. Maybe it is the motion blur thing. I didn't use DOF. Or maybe the icon i saw didn't really use MAX to create, could be illustration, like the Mac icon.

What is your Anti-Alias setting?
If you render with scanline, try set the Area filter a bit lower, like 1,2.
That will sharpen the edges, also explore the other AA-filters.

Thanks Conny. I use the Area filter at 1.5.

At 35x35, your image is too small for the AA filter to work correctly.

What you want is a sharp image, but the AA filter is attempting to smooth things out, and your rendering gets blurry.

If your Area filter is set to 1.5, then 3dsmax looks at each pixel adjacent to the pixel its currently rendering, and then looks another 1/2 pixel beyond that to detemine how to Anti-alias the edges. Essentially, 3dsmax is looking at a box 4x4 pixels wide/tall to anti-alias each individual pixel. 4 pixels is ~11% of your toal image size, so each pixel is getting blurred by ~11%. There simply aren't enough pixels available for renderer to make a sharp-looking image.

Example: If you open a 1000x1000 pixel image in Photoshop, and then apply a Gaussian blur of 110-pixels, you will get a pretty blurry image. This is basically what is happening when you render such a small image in 3dsmax with AA turned ON.

For small web graphics, turning the AA OFF will give you a better result. It will also give you precise control over the image transparency (Alpha) if you're creating .gif89 images with transparency.

well, you have the option of using another AA sampler. if you want to have sharp edges, use catmull rom. there's also an explanation of the AA filters in the max help.

I will look into the Max help file. vbmenu_register("postmenu_2364914", true);

Try using Catmull rom as your AA filter, it is highly sharp compared to the default area filter.
