Hello I was wondering if someone was generious enough to help me render a scene. See the problem is that my CPU's video card is a built in motherboard/crap so I get these really bad renders with the settings set to almost maximum.

My simple request is to get a little tip on my 3 point setup (background/rim, key, fill) and a render of the scene, just to see if its my gfx card or not.

If anyone is interested I will post more, just the thing is that the image is on my CPU and I am on my laptop.

Mental Ray, I can post you a render tommorow, with a file of the little project. Just need to find the thumb drive... and its 4:51 am here so time for sleep.

Right... mr doesn't use your graphics card, it's a software renderer. When you post a pic, post your render settings and what 3D package you're using.

Post a screenshot of your render settings as well as the image. As cbamber85 said it doesn't matter if you have a graphics card or not.

Here is the render I produced.

These are all of the pictures you guys asked for. I am using 3D Studio Max 2010 for the modeling and Mental Ray for rendering.

What is the thing? Your center of interest is now is at the border of the frame. You should focus on the product.

It's a metal tin that will contain a pair of Hurley Slip On shoes. I can produce a better render I think but I was just so mad to see this one that I came here as fast as I could.

Why you were mad? What's wrong? What's the problem?

Well I worked really hard at a shitty job to buy a nice computer and moniter but everytime I try to do something 3D it dosent give me the results i want. I was just looking for a cheap fix so I can render all my pending scenes and fget better at it. I mean I have self thought myself soo I do not know if its me or the computer.

First things first, why is it a bad render? All I can see is that there is noise on the tin reflection, I'm guessing that's because you're using a repeating tile map for the bump and it's wreaking havoc with the sampler. If this is the case, use proper reflection gloss on it.

Secondly, your render settings are massive, you can probably halve them and lose a negligible amount of image quality.

Also I suggest you read some threads regarding studio lighting, your scene is very dingy and the tin has nothing to reflect - this lowers the realism loads.

I mean I have self thought myself soo I do not know if its me or the computer.As a general rule of thumb, it's never the computer. They do exactly what you tell them to. 3D is very difficult, and rendering engines are possibly the most complex part, so my advice is to read a lot of documentation on mental ray. Not just what button does what, but how it works.

Thanks cbamber85 I will try to do more reading on this subject. Expect this scene to be in the WIP section soon, I already have the tin and shoes all done, just need to do a bit of texturing.

By the way I am using a MI material, satined metal I think.

This article is written for Vray, but all of the same concepts apply in Mental Ray:

If you need more info, look up "linear work flow" and "mental ray" on Google. I've been doing the same thing with Mental Ray in Softimage, and I'm loving the results.

EDIT:

I found a video which describes this process using 3dsmax and Mental Ray:
