Space Scene - lighting problem!
show user profile  cbflex
Hey guys need some advice...
I wanted to make a space scene that's built to scale. That means a huge huge sun and small planets. So I did just that with exact measurments of radius and distance set in place. For now I just have Saturn and the sun. My problem is the lighting... 3ds Max wont let me set the light to be as powerfull as the sun is in space. That's 3.75^28 lumens. I tried setting up a vraysun without vray sky in the environment panel but that didn't do anything...
So, now I'm using a 3ds max omni directional light that has no decay. Now my problem is that the rings of saturn reflect too much light to the backside and that the shadows are too soft. They should be film noirish. Any ideas?

Light naturally decays, that's why your rings are to bright.... as for the 3.75^28 lumens... i don't use vray but with mr daylight system you can set the sun the be (ies sun) and then change the lumens (lx) to whatever you want

I forgot to mention. I originally had a vray light that decayed, but it always made my Saturn have a lot of light behind it and everything. That shouldn't be happening... I'm so confused. I've played with everything, I feel like the physics for large large realistically scaled space scenes just don't work in max.

Don't forget that Saturn's rings are made of a shit ton of frozen water, which reflect A LOT of light onto the planet... best bet is to just make it look good, not try to replicate. It's impossible to duplicate the intensity of the Sun's power. If you were to , let's say, be 10000 miles away from the sun, you'd be dead. In max, however, feel free to get an inch away...

If only I knew that Max had numerical limits I wouldn't have wasted so many hours on this project.
I've been trying to simulate the sun's intense power. The sun has the power of about 3.75 X10^28 lumens... Max only allows 7 digits in the light intensity section and only 22 digits in the percentage increase section.
However, you're only allowed to increase the the maximum lumens by onle 14 digits, so 10,000,000,000,000% about. One more digit and the light actually stops emitting and the scene is black from what I'm experiencing. I just though the professionals did everything to scale so I figured I would do this like that too.
I wish they had listed the absolute minimum and maximum for all their sliders.

Furthermore, I wish 3ds Max allowed you to simulate actual physics. It doesn't allow you to simulate say a galaxy spinning, because a gravity spacewarp acts literally like 1 atom in the realworld containing the gravity that you need rather than say a huge sun that has volume and gravity. I tried something interesting one time, where I created a sphere of gravity spacewarps and throw some particles at it, and it did in fact imitate what a galaxy does except it ran ridiculously slow, no wonder.
And furthermore, in Reactor, say you set world gravity to 0. By the laws of physics, the more mass something has the more gravity it contains. If you make 2 objects have the maximum gravity reactor allows, it doesn't make an ounce of difference in the gravity of the objects.
Is there anything out there that would truly work by the laws of physics?

Sounds like max script is what you want, or any easy button :)

How would maxscript help me make lets say a simulation of the bigbang?

you're not going to simulate the universe in max :p max was made for visuals not physics

sounds like you need a "don't start stupid projects" button.

i'm all for doing cool shit but common, the universe to scale? lit physically? are you insane?

the only time you should be in real world scale is when there's benefit of being in real world scale; and space? the distance to saturn? you gain nothing by having it be accurate.

Can max even have that large scenes?
I never thought about this, does 3ds max have a space limit? if yes, what is it?

You just need to set the unit scale...

Id love to see how many people went to unit setup after that just to check if "Lightyears" was there
