some questions

[Guido Duba]

As I only now upgraded from AR4 to nXt, I miss some tools and or options.

I may be doubling discussions, but I cannot find the following in earlier discussions;

 

Is there no more possibility to render multiple views overnight by batch-rendering?

Are there no more procedural clouds?

I cannot find the list of geographical locations to set my sun to?

[Roy Hirshkowitz]

No procedural clouds and no geographical locations.

Batch processing is available from the WalkAbout screen.

I'm doing a walkthough, a street-scape and use to use procedural clouds with a 3 colour sky.

That would you use to get a 360deg real looking sky that can be used in an annimation where the sky needs to be everywhere.

A high-quality HDR would work for this.  With alpha-compositing the sky part of the animation could actually be rendered independently.

So this change would be found in - nxt box - under lighting - advanced - sky - HDRi.

or under lighting background - type - hdri. What is the difference?

If I started with a preset of Exterior is there any other setings need to be changed to get a solid looking background. (Yes I have a groundplane with this.)

 

Where is the setting to select the sky to be a alpha-composite.

 

The high-quality HDR you talk about are the ones under the nxt download material page (HDRI background)? Do you have a favourite that work well for you.

 

Ok just done a test {With london fire lane} and how do I show only a HDRi sky without the buildings but use the full sky+building to reflect off me model. Or do I have to select to different HDRi for each. If this is the case do I use the old HDRi from ar4 days which are just sky or are there new ones.(high-quality).

 

Sorry for all the questions but I'm doing a 360 fly around a louvre product for a screen company and they are happy with the white backgroud at this point but want to wow!!! them with a cool background and shading look.

I really don't have a clue what your asking at this point?  Are you working on the louvre or on a streetscape like you mentioned before?

 

The lighting - sky settings determine what's used to light the model (for sky light).  You can change the visible, reflected and refracted background separately if you want, using the Background tab.  Be careful though, with a metallic object like a louver much of the lighting derives from reflection-- you can really screw this one up by messing with reflected backgrounds.  Also note that any background changes you make can effect exposure, so the lighting in the object may change.  You'll need to play around some.

Alpha channel is always present.  Save your animation or single frames using png w/ alpha if you've got an editor that can handle compositing afterward.  Using a system like this you can actually render the background all by itself and composite the two together when you build your animation.

Thanks Roy

I,m working on a street scape with 28 home, Louvres products for a screen company and a solor company want to show pannels on a standard home. So Flat out with work. But all of them need backgrounds that can do single shot and animation and mantain a set background environment. You have help with your comments thanks, and your right about the metallic object, not hard to mess it up.
