Hello,

I'm new in using SU Podium. Im read a lot of documents / tutorials. For some obscure reasons, i have problems by rendering some of the SU Podium objects from podium browser. For example, you can see on the attached picture that the table has aliased edges. I tried to create my own presets with more anti-aliasing, but no result. I tried to smooth edges in skechup, i tried to set anti-aliasing in material editor, i tried to play with the resolution, i try to scale the image in Gimp, but the result is allways the same !

Have anybody an idea? I'm sure it's only a little detail, but i cannot found it [confused].

Thx

PS1 : sorry for my poor english :-).
PS2: this is only a test. No comments about the global result [wink]

You can see the same problem on this other try (look at the table).

Without knowing which preset you have used, it's difficult to comment.

One thing you can do is increase the edge smoothing for materials which show these problems.

Hello Bigstick,
Thank you for responding. I use the Interior_High preset (1.0.8), but i tried other ones with the same result.
For the table on picture one, i set the edge smoothing to ultra. You see the result.
It can be (i will try it) that the camera angle has to be changed. Perhaps a possible solution. I'm going to continue the tests.
If you have an other idea, please post it :-).
Thank you.

I don't think its the same issue on the 2 renders.

I think 2nd render issues is because the 2 surface are too close to each other. On the 1st one, try to render with the fine_AA preset.

I wonder if there is a problem with the per material AA settings? How does it render at standard resolution?

Hello everybody,
Ok, i ran 4 tests:

1. Render in Interior_High_1.0.8 1024x768
Kitchen_1024x768_High_1.0.8.jpg 

2. Render in Interior_High_1.0.8 2048x1536
Kitchen_2048x1536_High_1.0.8.jpg 

3. Render in Interior_Fine_AA_1.0.5 1024x768
Kitchen_1024x768_Fine_AA.jpg 

4. Render in Interior_Fine_AA_1.0.5 2048x1536
Kitchen_2048x1536_Fine_AA.jpg 

We can see that at low resolution, the aliasing problem still appear (now no more for the table but for windows and oven).
The problems are mostly solved with higher resolutions. It's so ok for me so. Thank you for your help [smile].

The last problem i have concerns the edges of the roof. We can see exterior light along the edges. I think this is probably a known problem. I tried to smooth the edges but it did not help.
Do you have an idea?

You need to model with extruded (thick or solid) components. If you model with single planes, this is what happens [smile]

Before you do this. Activate the monochrome view mode, and reverse all the blue surfaces. It will solve those light leaks issues.

Thank you Maître érudit. Faces were all reversed (with the left click reverse face tool plugin).
I made some other tests. I cannot solve the problem definitely (but it is now better thanks to the comments of the forum). If you look at the TV-furniture, you can see the aliasing problem ("it" is back).

Because my renders all base on real house plans, the camera is close to the scene. Perhaps too close...

In summary, i checked:
- that all faces are on the blue face
- that all components are extruded (no single planes)

i tested:
- Preset Interior High_1.0.8
- Preset Interior Fine_AA_1.0.5
- "High" resolution
- Changing camera angle

So if somebody has an other idea, welcome [idea]

Thank you.

Can you render with the info bar on? I'd need to be sure what preset you used with your image.
