Scene states / batch rendering?

[RevitGary]

If you are making many different renderings from a model. Interior and exterior do you have to make a separate scene state for each view when batch plotting? I am thinking this is the only way to get good results.

Can you explain a little more what you are doing? ...plotting from Max is not recommended. Or did you mean batch rendering?

[RevitGary]

oops ... I meant batch rendering

[Crazy Homeless Guy]

Separate scene states will certainly work, though they are often not my preferred method. Mainly because the saving of information happens behind the action. Meaning, you can not easily see what is being saved and what is not, and of something changes, you have to re-save just to be sure that the scene state is still intact.

 

Maybe I am exaggerating, but I think it is a bit on working on the blind side, and hoping things work out.

 

As an alternate to scene states, you can use frames to save variations. Frame 1 has the sun located in this position, this exposure applied to the viewport, and this material option. Using frames is a little easier to troubleshoot if something goes wrong.

 

Another good alternative, and probably my preferred way to do it, would be to Xref your model scene into a blank file, and set you lighting up in that file. This way you have your exterior/dusk/and interior lighting all independent of each other. I think this is the cleanest and easiest way.

OK I am trying to figure this out. I am not much on animation.

I have made a camera follow a path. Can you make each frame have its own camera view?

 

example, frame 1 use camera 1, frame 2 use camera 3

 

or do you have to reposition the same camera in each frame for each view?

Scene states with Batch render is what you are after.

 

Scene states with different sun possisions works really well. It gets a little muddley when tring to hide/unhide object with different scene states but is still possible

 

In Batch Render you cna assign different scene states to each view/camera

 

Major problem is if you are changing exposure, these are not saved with scene states.

I am changing exposures

[Justin Hunt]

Then you will have to animate the exposure changes, still use batch render, just assign the relevant frame for each veiw.

 

If its just the views and exposure changing then go with CHG's suggestion

 

Master Zaps has made a "hack" physical camera which will change exposure control on a per camera basis. I have played with it and it does work although I havn't used it in production yet. search his blog for it

Hi Gary

You can use just one camera and autokey. All you do is turn on autokey go to frame 2 on the slider move your camera to a different position (this sets a keyframe), move to frame 3 move the camera sets a keyframe. Now you have 3 different frames to render and three different images.

If using this method just make sure you have autokey on when moving the camera as it can mess up. It's not just for camera position either you can move objects, change materials etc.etc. The list is endless!!

Hope this helps

this works if all your images are the same resolution and aspect ratio. But not if you using different resolutions, then you will need batch render.

WOW that autokey makes life simple

 

It doesnt seem to work with gama settings.

I guess I will have to do the exteriors and interiors in separate batches.

Everything else seems flawless and easy .

 

By the way I have heard gama of 1.8 is good for exteriors and 2.2 for interiors, is that coreect?

 

Thanks soo much!!!

[Justin Hunt]

gamma should be 2.2 regardless if its interior or exterior. Change your expose instead.

 

Gamma is not only tied to what is displayed but also how the maths is done to display thiings correctly. This included lighting calculations, shader calculations etc.

No problem Gary glad to help!!

Once you start using it though don't move your camera without turning it on or else it will mess up all the frames. This is really important I have been caught a few times. I usually make a backup of the scene so I can import the cameras should it go wrong on me.

very good point, learnt this one the hard way
