Please can anyone suggest how I can get MR beta to render exactly what I see in the camera view.

Sometimes it renders exactly what I want and other times it renders much closer in or further out.

Have you followed the "Setting the camera" tutorial?

I have used this method of copying the camera distance to the 'L' field before without success and trying it again now it still does not give the desired result.

Very frustrating because with 6,000,000+ triangles to write and render it takes ages to discover what it has decided to render.

On many things the camera position, angle and field are not so critical but I am rendering the confines of an Airbus cabin and I need to be just inside the cabin walls taking a very precise shot.

Any other suggestions?

Looks like you maybe having the same problem as Mike, have you read this thread? Sorry I don't have any other suggestions.

Did you make sure your lens setting are same in sw as maxwell. SW switches to custom when you move target. Reset it to 50mm 35mm whatever, then make sure in Maxwell settings you enter the same in camera settings.

Thanks for the suggestion, it has not improved matters but I am becoming better at guessing how the render frame might differ depending on wide angle settings etc.

I don't know if there is a relationship between object size and camera position, but I noticed that after deleting a large piece of geometry from my SW scene the camera views changed (zoomed in) without me changing anything else.....wierd!

Just out of interest I noticed that you are running a PC similar to mine.
I am trying to render an aeroplane interior in Beta with several flat lights and 6500000 triangles. Materials are diffuse, plastic and some Aluminium.
It has now rendered for 50hrs and is still quite noisy. I have set total render time to 100hrs; would you think these render times are to be expected with my computer?

Whoa this sounds too long to be very noisy.

Adman this might have something to do with the total reflectance in your scene. If you have any white materials make sure the rgb is set no higher than 224 for the color values. Nothing is pure white in reality, and this will contribute to a ton of noise if you have the color jacked up to pure white. There was a thread somewhere on this. Try doing a search on reflectance. Also if you have a plastic that is reflective make sure the combined values of the specualr color, and the diffuse color do not go over 224. I have a hunch this could be contributing to your noise problem.

Another thing is if you have glass in your scene make sure the abbe is set to around 155-200. Make sure your emitters are fairly large also. Small emitters can make the scene much noiser. If you post a screen shot of the image you currently have I might be able to give you more specific help. Without seeing your scene I am only guessing what could be causing the long rendertime.

Hi Eric

Trying to post an image....hope it works.



Any thoughts on why it should be so noisy after 50 hours?

Adman

Enjoyed looking at your site and work.

You could change your lighting to simple surfaces, Studio allows you to set the normals on surfaces unlike SolidWorks.

[Eric Lagman]

Why not just use physical sky for something like this? Would it take longer than using emitters? Also does each window have an emitter? If so I would just change it to a long rectangular plane that spans the length of all the windows. Small emitters are very time consuming compared to larger ones.

How would I keep the enclosed volume effect using physical sky? I'm not sure I understand what you are suggesting.
If you mean sunlight streaming in through the windows on one side, I think you are right, it would add something to the shot......will try that next.

All the lights including the spots and windows are powered by only eight longitudinal flat planes with different outputs. Can't think how to make it any simpler!

Improving all the time with good advice and familiarity with RC5.

Thanks

Yes I meant physical sky with Sunlight streaming through the windows. Dont use glass in front of the windows though. It will take forever to clear. You might have better luck positioning the sun within studio, but I know you were having some issues getting your model in it sounded like. I would take a look around the forum to see if emitters render faster than sunlight. I havent played around much with the sun. My hunch is emitters might be faster.
