Topic: A C3D.. render issues

[mjfarrell]

Well, I pasted them all in and they seem to have kept their material properties...so it should NOT be required that you rebuild your corridor entirely.

However you still have some portions that go to zero, regions that overlap other region data, and perhaps some bad profile data (arising from using the GE surface I surmise)

[mjfarrell]

close inspection of the file reveals...one just might be better off creating the corridor as a single ALL encompasing one
and or if one stays with all the seperate ones...
AFTER the design is 'finalized'
Creating a detached surface from the corridor...removing some of the triangulation, then pasting in the islands would produce a better result for rendering.

[mjfarrell]

Part of the issue with your island not showing up correctly is that the corridor 'only' comprises the curb.
When this surface is pasted in, the inside of the island is confusing the software, so some of the pavement
surface from underneath is being blended with the concrete surface from above.
Again this is due to the manner that the links, and feature lines are connected within the corridor model.
IF your model was a single contiguous model most of these issues would resolve themselves.

Here is, the corridor done a lot smoother withought all the overlap and the dummy corridor. also I see what youre saying pertaining to the islands, but I, do you mind letting me know exactly how to do that.

[mjfarrell]

two options...
the first might solve the issue
add a link off of the special curb only assembly, assign unique link code,and be sure to assign proper material properties to the  link code in the code set the surface should fill in the islands

Otherwise you are going to want to build those islands within a SINGLE unified corridor model so that the link codes and feature lines they generate connect more correctly.
Take a look inside the corridor properties and look at the feature lines tab to see why...this is partly due to your having the pavement continue under the islands...and partly because of how C3D connects the feature line links.

If I understood your question(s)?

[mjfarrell]

actually take a close look at Damen North Spl profile and alignment, (actually most of them)...there is something way bad there that is at the root of the problem...unless the using the DUMMY as target has fixed that issue

[acurr3]

now, Ive created another surface that actually shows the center islands in the object view, but when I select the surface and then use the render command, nothing at all comes up.

[acurr3]

her is the current file

[mjfarrell]

take a Quick profile through the areas where the surface appears to not display when rendered...
you will see that you have surfaces overlapping surfaces...and this is confusing the render engine
setting all other surfaces to a NO DISPLAY style I get the attached...

[mjfarrell]

I would rather that you actually have made a DUMMY corridor, that wasn't a part of your 'New Roundabout' corridor.
This allows one to reference information being created by the DUMMY within the design corridor, without creating self referencing loops within the data.  Sometimes this will cause a corridor to show as constantly out of date, or rebuild infinitely.

Are you next going to add a motion path and send a camera around and around the roundabout?

[acurr3]

alright.. got it all to work.. now.. do you know what I can do to get grass in the middle of the island..

[mjfarrell]

extract the inner most feature line from the corridor....use it to create a surface called Island of Grass add that single Feature line as a 'breakline', with desired style and render material.

Or

as instructed earlier hang a link width and slope generic link of the side of the assembly that creates the island, being sure to assign the desired point, and link code to the link to allow it to create/render the proper materials. The nature of how C3D connects the feature lines will fill in the rest of the oval when it makes the surface triangulation.
