hi guys

I would like to share some information with you that can be helpful to lit this scene.

Originally lamps were used to lit this famous central hall, they can be barelly seen in this old photo (notice the volumetric effect BTW):

Nowadays natural skylight and spot lights are used. The spotlights main task is lighting the painted ceilings. Example:

There are dozens of images about this hall in Flickr. Input "london natural history museum" in the search tool. They can be helpful to get 'a second opinion' about a particular look. BTW some of those frontal images were really helpful to model this work.

There are two lamps types in the 3D scene, located at both ends.

I've got a question regarding this challenge and the previous one (lighthouse),
the scenes are only available as polymodelled objects, no NURBS models.

It's the first time I render larger scenes like these...

My issue: rendering time in Rhino 4 + VRay
it takes about 10-20 minutes for a "quick" test render, without any materials set up,
is it because of the polycount, or because of incompatibility with the nurbs modeler rhino ?
(I know rhino converts a nurbs object to a polygon mesh before rendering, but I want to be sure it doesn't make a difference before I go on trying to make my renders faster)

Hardware: Q6600 2.4ghz, 4gb ram

Render settings for the test render were:
reso: 320x240
GI on => primary IR (multiplier 1) => secondary QMC (multiplier 0.8)
IR map settings: -5,-3 + standard values

Any help or advise would be appreciated

Thumbs up jeremybirn,

Hi jeremy, I still have problems with max file. I'm using Max 9. I already know that I can import obj. dxf. ... ... but where can I find them?

thanks for your info.

I'm looking forward to take the file, to work on it.!!!
  11 November 2008
Yes.. the max file posted is a Max 2009 file.... some normals are flipped.. but I have posted a max 9 version.. all you have to do is flip all textures to 2-sided... and they'll render ok.... just viewport will have the flip issues.

thanks for the heads up MrHoo and jeremyBirn, I didn't know objects couldn't contain ANY UVs. I thought maya created UVs at each vertice at the time of vetice creation (or somthing along those lines). I know maya doesn't nicely lay them out for you but I thought they at least existed. I was thrown for a loop there.

Now that that's solved, on to those darn stairs... those are going to be fun.

got the scene!

thanks mmoses00 !!!

At last! I've got the scene, I'll begin working on it!!

Some more work on the light setups. Also added a little level correction and grain in photoshop to get a sense of what I may do once I get the layers into a compositor.

Pretty happy, though I'll probably tweak as I add some objects and texture, which I can hopefully start soon.

narrowed it down

Ok, I think I'm happy with this mood and camera/light angle, I'll tweak it a lot in post though I'm sure :/. T-rex took a visit to zbrush and got transposed into more of an attack position. Cranked up the GI settings for this render. Vray dirt override material. Some post work was done to this to see what kind of look im going for. Time to start on all the other good stuff.
Much more needs tweaked.

Tweaked my image a bit. My basic light setup is a combination of spotlights, GI and HDRI with Caustics also turned on.

Natural History Museum progress-1

Hey, All.
Here's my first stab at this scene. It's little more than a sketch at this point. I'm hoping to create a feeling of menace in this scene, maybe adding some school children to the left side of the staircase. I may try a few more cameras, but I do like the one point perspective on the grand stair. I'm using 3DS Max with Vray for GI and photoshop for post.

Thanks to Alvaro Luna Bautista and Joel Andersdon these models are AWESOME!

A few first drafts. i JUST got the file setup this morning, No real materials yet. LONG way to go! Still playing with cameras and light angles. I've got a few more angles but apparently there's a 3 file max... I'll have some more updates soon. Maybe a night shot. I'll figure that out once I decide on a camera...
