Twilight project

Frederik · 16 Jun 2010, 12:39

OK... Took a quick look and made a few adjustments...

1.) Removed some parts from the light components
2.) Added a square mesh and applied an Emitter material using the TWR material editor
3.) Adjusted the TWR spot-lights
(Decreased the light strength from 5.000 to 2.000... Adjusted the Falloff to 120 degree and the HotSpot to 90 degree)

I've attached the model below and hope you can learn from it...

P.S. I also moved the floor up... You can see in your render that it's below the pillars and the walls...
Please also be careful when placing the light components...
I moved them up (app. 7,2mm) in order to prevent light leaks...

P.P.S. Sorry about the TWR watermarks... I'm currently at the office and had to use a demo version of TWR...

thank you so much. that helped a lot. I'm going to update the scene as soon as posible. I played a bit with the light. 2000 was to dark. I setted the light to 3000 and it looked great. Many things are clear to me now.

turn on the 'monochrome' face style. the white ones are good, the light-blue ones are bad...
When this kind of stuff is important in a model, I like to make the back-color a bright red... this can be changed in the styles/edit/faces dialog.

Back faces are real killer for most renderers - you might get excessive reflection (like in Twilight or Kerkythea) or faces won't render all or they render black (it's all up to the engine). I don't know many render engines that can handle back faces, even in Thea they do matter, if one uses displacement or instancing brush. Making back faces to a strikingly different color, do help a lot. There is also a neat style for troubleshooting the scene.
Second common problem I seen is that light sources do intersect with the geometry. Third common issue is the scene scale - when you use a physically based renderer, you must model in the correct scale.

My pleasure...

Eeehhh... You got me confused there for a second...
It's not 2000 (two thousand) but 2 point 000...

A question... Can I ask you if you play games on the computer you're also using to render models with...??
Reason for asking is simple... Since most of your renders seem over exposed, I tend to believe that your monitor is calibrated very dark...
I've seen it before that users who are using the computer to both play games on and also render models always seem to be over exposed...

No I'm not gaming but the lights in that room are really very strong. I will show a picture after the reconstruction is finshed.

here's the brand new render with perfect TWL- lights.

jo-ke · 17 Jun 2010, 15:48

I just played around with the spotlights, edited the emitter and turned the direction. Now it comes pretty close to reality.

Frederik · 17 Jun 2010, 17:56

Looks great, jo-ke...!

To make it look even more real, you can exchange the spot-lights with a suitable IES-light...

jo-ke · 19 Jun 2010, 07:43

Yes IES would be the next lesson for me.

I'm loving it playing around with the lights. I've just added many flourescent lights and a new spotlight at the neightbour room.

here's another render...

pyroluna · 20 Jun 2010, 10:58

very nice, jo-ke! I always like to see such an improvement in a project!

jo-ke · 20 Jul 2010, 18:27

We started this week with the reconstruction. I hope that we are finished at the end of the week.

Frederik · 21 Jul 2010, 08:38

Ooohhh... It's always great to see a project comming to life...

Gaieus · 21 Jul 2010, 09:55

Is that a render or a photo?

jo-ke · 21 Jul 2010, 13:43

and the next step is done

jo-ke · 23 Jul 2010, 14:56

most of the work is finished. Next week, we're going to make the decoration.

jo-ke · 24 Jul 2010, 11:48

nearly finished.

Frederik · 24 Jul 2010, 13:04

OK... Although it's easy to see the difference between real and render, the render is really good...
As you can see yourself, the fake emitter in the spot lights need to be increased in power and the floor also need some extra glossiness...
Overall really nice to see this project evolving...

shura · 24 Jul 2010, 13:11

Right Frederik, I second that. It is very rare to see a whole project documented - I like to watch that.
Good job jo-ke!

jo-ke · 24 Jul 2010, 15:26

thank you very much for your c+c. it was very helpfull.

I am going to make a new render and a new foto next week, when everything is on its place.

jo-ke · 31 Jul 2010, 11:44

decoration is done, so I've done a final render.
