I will post all my questions here, and if anybody else wants to they can post theirs here too. My problem is with clay rendering, whenever I put a skylight in an interior room the object turns completely black when I render it. Anybody know how to fix this?


Are you still wondering? Well if you remember my modeling room, A SKYlight can't show into a room that is SEALED showing no sky. You have to delete the overhead face, but it will be a dull gray. Too get a more white render to bring out the details like my modeling room, delete the face that will not be shown from the camera's POV including the overhead face.
Here's an example:

This is an example of the one overhead face deleted showing a dull gray render. The more skylights you add to this one won't make it any brighter. The image will only get less sharp.

This an example of two faces deleted (the other one is to the left of the view point).
This also had another skylight (total of two) to bring out more details in the gun as seen more than the dull gray one and has a sharp presentation as well.
You can also add omnis too rooms that are enclosed but will not be of best quality. A correct distribution and combination of skylights and omnis will create tremendous clay renders. That is something we all have yet to learn.
I hope this helps you on your journey to create better renders!
This above is for clay rendering and I will still like to expand the varieties of outcomes of renders so if any has some tips too add please do so we all can learn from each other and create more wonderful beautiful renders.
(NOTE: The reason this is in this section is because the majority of the H2V members come here and noobs also so we all can learn from these tips from one another)

Use the Catmull-Rom anti-aliasing filter.
Use the Hammersley supersampler.

The best thing to do is get your hands on a copy of vray, which can render with far better quality inside or out. (It's hard as hell to learn though) Another thing you can without any other plugins can be done with a simple Omni light.

Please note that the room isn't anywhere near finished...

Anywho, a omni light itself would look like crap, but you can tweak its setting to make it look like my render. I changed the following settings to get this render:

Shadows: On, area shadows.

Shadow parameters: Density, 0.6.

Area shadows: Shadow integrity, 4. Shadow quality, 4. Sample spread, 30.

Just mess around with those setting to see what they do. This is a sealed room btw.

Llama, that looks pretty funny :)
Not as in bad but the render just makes me laugh, the spheres on the wall look silly and just don't belong IMO.

That don't make since now, but they will be dome lights later.

A rendering tutorial I posted a little while ago. Outcome is similiar to this render, same setup just differant coloured lights.

Use the Hammersley supersampler.

How do you set those settings, and is Vray a plugin for MAX?

Vray is a thirsd-party renderer.
Mentalray comes with MAX.

also alot of untruths are claimed in this threa, but i dont care.
