X5 Vs Thea...

[HumbleChief]

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.

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.

Nice design - but as you say too drk. What I find interesting is that the low light creates a patern like a high setting ISO does on a DSLR camera. That is very interesting that the render engine places that noise into a low light setting too.

still looking for the Like button!

still hoping for the latest update fix.

Thanks Jintu!

Ok so heres the latest X5 raytrace dilemma... the first one is done with all can lights as spot lights, the second in point lights and the third all spot lights except for one point light behind the camera. Im really not liking the spot lights because they have a lot of light bleeding going on around the edges of the window casing, yet the point lights definition around the cans are unrealistic. The mix between the two seem best but still dont understand why Im having the affects with the spot lights. In all pics, lights were adjusted to 100% specular and emissive.

Chad, it seems that the spotlights exacerbate the light bleed problems from photon mapping. Do you get the same light bleed problem when you run the all-spotlight render with photon mapping turned off?

[Chad Cardin]

Kathleen,

Yikes! Im still new at this whole raytracing... I dont even know where to select or not select photon mapping. I was just recommended to turn up emissive and specular to 100% but dont remember when you should or should not select off photon mapping. Can you fill me in??

[Chad Cardin]

Ok I found some of the setting with photon mapping etc. Problem is when I turn off photon mapping the quality of the rendering is reduced. An example of this is the stainless steel refrigerator becomes just a black surface. So Im trying to figure out how to get high quality results without the light leaking in the corners of the raytrace. Does anyone know if this is a bug with the program or is there a setting Im missing?

Photon Mapping: Try to turn off the sun (sunlight= zero) and do not use environment light (sky). All those leaks will be gone.

[Chad Cardin]

Jintu,

Thanks for the reply. If I turn off the sunlight and environment light, wont that not allow sunlight to come into the windows and make the raytrace look less realistic? I reviewed some of the pics you posted on here and they look really good in part because the sunlight that comes in mixed with interior lighting has a good mix. Could you clarify this? If possible, could you post your screen shots of the settings, so I can better see what selections you make in your renderings with sun and interior light selections?

[Chiefer]

No sunlight and env. light= no leaks.
