X5 Vs Thea...

I am curious whether the areas considered to be light leaking are actually a condition similar to occlusion, but instead of darkened areas we are getting additional light bouncing in these locations.

Not to say that there are not leaking situations as well, but some of these like the ones by the stair rails look like they may be from some other cause.

It would certainly be good to get to the bottom of this. These glowing areas have been a problem with X4 as well.

Good point Rod. 'Leaking' is probably (definitely?) the wrong term but it looks like a 'leak' in most cases.

Agreed

This is my first raytrace. Its too dark and many other issues around it since its my first but it only took a few minutes and looks decent.

Hope they are getting the hints.

I can settle without photons given the right settings. This is under 8 mins.

Dam* I LOVE that floor!! Heck LOVE that entire scene!

Does anyone know whats going on with the lights in these two renderings? The first one is my latest one but if you notice the area where the can lights are is just a giant blur of light compared to the second light where you can clearly see the can light. I set the setting similar to 100% emissive and specular. Im not sure why the look so different.

Any ideas?

[Chad Cardin]

Figured it out! Finally! I opened to two plans and everything looked the same BUT the first pictures can lights, although the same size, color and settings was set as a 'point light' versus 'spot light' which was in the second picture. Ahh thank God I got it fixed. Does anyone know what the other two light types are used for... Spot, Parallel and Point lights? Spot lights seem to give the best results for most realistic can lights but what are the other two best used for?

Nice start!

To brighten a scene uncheck "Use camera view settings" and make the color medium gray. Lum: 200 to 150.

Thanks Jintu,

I will give that a try on my next raytrace!

[Chad Cardin]

Jintu,

I dont see a selection for lumination? First day, can you tell?

In fact, since youve been doing this for a long time, can you tell a lot of us on here who have never done the raytracing some of the differences and options on raytracing? For instance, is it better to use the raytrace wizard why or why not? As far as numbers go on settings, for sun, lights etc, can you give us an average number you might recommend on the different settings so we kind of know where to start? I understand there obviously will be differences for indoor or outdoor settings but if you just give an average number like you listed 200-150 it will help us stay within the range to get a decent raytrace.

This might seem mundane for those who are experienced with this but Im hoping it will help give those of us who dont have as much experience somewhere to begin.

...or keep "Use Camera View Settings" checked and change the 3D 'ambient' camera setting in the 3D Defaults dbx.

Thank you.

Thank you.

Jintu, you got new machine? Looks really sweet. Are you happy with it?

Windows 7 is more organized. I'm happy.

Hi Chad,

Selection for Lum. is in image 1.

- Indoor and outdoor selection from Launch Wizard affects light settings in the Ray Trace Option dbox. EX: dark outdoor will give direct sunlight intensity of zero.

- It is better to go directly to the Edit menu of the Current Configuration than going to the Launch wizard because you will have full control of the settings.

- Turning on "enable environment light" makes a subtle difference but takes a little longer to render but not as long with photon mapping on and best of all no lights leaking.

See examples below:

Image 1: my preferred raytrace settings

image 2: sky env. turned on (7 - 10 mins),

image 3: sky env. turned off (2.5mins).


Hope this helps.
