Rendering with 3 point lighting, it's all new to me but I'm getting the hang of it, I THINK.

Anyways, here's two shots with the jaggies at x1024 screen and 100 resolution. It was originally at x600 screen and x72 resolution. Will try for 300 resolution this time but I get a lot of artifacts and brown pixels in the whiteness of the model?? I run a laptop here without actual graphics card [it's on-board] so I think that might have something to do with it.

The third shot is just a screen cap, no render, showing how clean the real model is without a render. I'd love it if my renders could be this clean but with lighting. There are still some jaggies on the model where it meets black but no artifacts. How do I get rid of jaggy edges??

Any help would be appreciated, thanks.

What were you rendering with? The software renderer, hardware renderer, or mental ray?

Try changing your render setting,windows/render editors/render settings. click on that should then click on quality should show quality mode change that to say production or preview....hope this helps dave

Edit: also dont have all three light at 100%, one at a 100 the others say 30 to start with but you will need to play about a bit

Its the onboard card. Thats how important the card is to render this stuff

the third image as you say is open GL which again will improve a bit more if you get a new card.

I remember this hassle many years ago when I first started out. Have a look around fo a cheap gaming card, that will sort it out. Theres no need to break the bank to get a good render out providing the machine can cope in the other areas like ram.

The video card doesn't really matter when rendering, that's only for the viewport. Mental ray, or the Software renderer are pure-cpu related activities.

If you're using Mental ray, change the quality preset to Production, same goes with software; and those edges should be dealt with. Another thing you might want to look at, is if one of your texture maps is causing it. Something like a displacement map, or bump map. Try assigning just a normal default lambert to the object, and see if it renders properly.

Imagination is more important than knowledge.

LOL. My bad, did I say render, f*** Im losing it. too many hours in a dark working environment.

the renders themselves are the result of non compatible hardware basically, having onboard graphics cards etc will not help as the whole thing will be in standard VGA. As I said I have had this before many years back, you can tell by the dots on the actual rendered images. The third image is open GL so that doesnt matter.

Actually, I had the same problem. The edges were all appearing jaggy and I searched google, sent me to this thread (one of the links)... but it didn't solve anything.

Then I thought... what if I actually save the render as an image? What happens then? So I saved the render with "save image" as a JPG. I then opened the JPG and it was all perfectly clean.

So you should try and save the render image and open it and see if it's still present there.
