I thought it should have its own thread since its a question on its own different of the other 2 i've asked.
I was wondering if you were going to get out an update on your edge line fonction giving us a choise of colors when rendering our model with edge lines on.
What i'm experiencing on my renders is having a great image but the black of edges lines having just a tad too much of an impact on the final result.
I know just getting a bigger size does help but since we don't actually have the dpi option (or didn't see it anyway) I actually have to make the render 5 times bigger just so closer edge lines don't make a larger line on the result and then convert it on a smaller size with higher dpi.
Its just an ides I had thinking up on the last week or so.
Thanks

It turned out that the plant material is one that just doesn't work well with the SketchUp Hidden Line display.
We can fix the problem by one of several things. Once we saved and reloaded the texture image for that material and that fixed it. Once we just clicked on Reset Color for the material and that fixed it.
I didn't see any particular pattern to it on a couple of different machines.
No, its actually not your model.
I had the .skp file from the technician that was working for us from another compagny.
I don't think he was working with Irender NXT.
And so, didn't know about his foliage problem.
And I did sent you the file with the upload tab. You tried it and didn't get the same problem so it might be just a checked option I have misclicked but i'll try with another one.
Or could you post, or send us, a small sample model with some of that foliage in it?

I Actually found out what the problem was just by coincidence and by looking at the foreground line images.
The problem was the bos formed by 1 type of foliage (which I don't know where it comes from since it was originally not my file) that blocks the lines made by the foreground rendering.
Added the 3 images supporting my point
- rendered image
- foreground lines
- rendered scene
I was wondering, I will get new foliage for the model but any ideas why it actually did this?

I'll make another try on a big rendering tonight, I'll make sure I get a copy of the statistics to make sure I don't forget anything.
Honestly, I actually didn't try looking at the foreground image. I don't know why I didn't but seems like I forgot that part. I'll try to do everything you say, Hope I won't forget anything.
I'll re-post tomorrow with results.
Did you look at the images sizes that I mentioned in my previous post to see if they were the same when you render to the larger size, the size of the rendered image and the size of the Foreground_edges.pngimage? If they were even off by one pixel it could account for the edges being stripped during a resizing of the png image.
Also, did you look at the Foreground_edges.png file which gets created in an image editor (also when you are rendering to the larger size) to see if the missing edges were also missing in that image?
Using the sketchup size seems to solve the problem but having to render at 1614x892 get me to my other point. We are doing big posters with the render on it (about 4000x3000) and we can't afford to just expand the original 1614x892 to maximize it and loosing the resolution on it.
Point is, I have to keep an around 300-450dpi resolution and its already a tad lower than that at 1614x892.
Any tips?
Sorry, I was waiting to hear from you. I had thought I had sent you a message after I rendered your model.
The edge lines came in fine for me here.
One thing...for the "Use Edge lines for foreground" to work, you have to be rendering in the exact same resolution as the SketchUp Window, since that's the image size we use to make the foregound image. Otherwise the foreground image might be shrunk and some lines might disappear, or the lines won't match the rendered geometry.
Could you check and see if that is the case.
The foreground image we use is saved to the disk when we do the rendering.
Could you look in the Statistics for the rendering and get the path to the edge line image, and take a look at it, to make sure that the lines are there in the image?
You can see the statistics by bring up the About box in the rendering window and clicking on Statistics. You should see a line like this near the bottom:
snxt_foreground_image:C:\Users...\nXt_batch\nXtBatch_Images\Foreground_edges.png
Please open that image in Paint and see if the edge lines are missing in that file also, and let me know what you see. Also look at the statistics and see if the rendering is the same as the dimensions of the foreground image.
Also near the top of the statistics: Resolution: 1036 x 794

The 2 point perspective resolved the sketchy edge lines problem but I still didn't get an answer for the missing edge lines. I've sent the model a couple days back but still... nothing.
Here is a new rendering made this morning, problems seems to be on all models. It doesn't seems to be location wise but maybe a camera problem I can't seem to figure out.
Attached 2 images with different view point.
Its a minor issue but the city we are promoting the project think its a major problem. And since i'm the only one here working with 3D modeling, I usually get the blame.
