Rendered "Sections" in black-how to?

rob2218 — Thu, 11 May 2023 10:09:14 GMT

How do I get my "rendered in lightworks" section to come out looking like the model section cuts look in Archicad?

The objects that are in section I'm looking to make them "black" while using the "Lightworks" rendering engine.

They only show up in black in the actual PLN model. How can I render them so they show up in "black" using the Lightworks rendering engine?

Postcards From the FRINGE:

I don't believe there is any EASY way to accomplish this...

1. Make your RENDERED SECTION by SEOing with a BLACK BLOCK and be sure to check the INHERIT MATERIALS function.. Brutal, I know, but you can leave these section cutting blocks in your plan and simply move them DOWN so they don't cut anymore once you've rendered... Again, brutal, but you can maintain your exact section cut next time you do it....
NOTE: you can then change the color of the CUT ELEMENTS by changing the color of the BLOCK.

2. You could do the same thing with an OBJECT (big block) and maybe the other GDL gurus can figure a way to have it "show / not show" (or cut / not cut) based on layer combination!... So only 3d Section Layer Combo actually draws the cube... It a stretch, but hey, these are postcards from the Fringe...

3. You could also make sure that all the MATERIALS of all the elements were BLACK, but that's just sill and unatainable..

4. Easiest method: OVERLAY your SECTIONS over your RENDERS so the black shows.. You can manipulate the FILL overrides to show only CUT FILLS (and not the colors beyond) and simply lay your rendered version behind...

Wow.....with all of Archicad's programability and functionality and there's no easy way to make "Sections" rendered with the cut fill as "black" rather than the "white (clear)" color you see there? Amazing.

Black silhouetted sections are basic in presentations.

If i understand the problem correctly:

Use the Marquee to define the visible parts of the model.

Visit the 3D Cutting Planes Dialog and define the cut plane as black, or whatever.

Create an elevation view. You'll see your selected color in OpenGL and it will render the same.

Here's a related thread from just yesterday [Peter Clark's solution]:

Well, there you go! Thought that only worked if you USED the cutting planes... (which I hate to do)...

Thanks Dwight!

I know what you mean. Cutting Planes are cumbersome and primitive.

will give that a shot Dwight...thanks.
I knew there was some "trick" to making a simple "section plane in black" mode without having to go thru all that Photocrap gymnastics....

Re: Rendered "Sections" in black-how to?

Well....didn't seem to work.
I "SEE" the cutting plane as 'black' in the actual 3d sliced off model elevation view but when I render....still comes out looking "white" (hollow) and not black.

Where do I adjust the rendering to show the cut plane as "black" while I'm using the 'Lightworks' rendering engine?? that' what I'm looking for....to be able to render using the Lightworks rendering engine and have my cut planes show up as "black".

Re: Rendered "Sections" in black-how to?

Here it is with the cutting plane colored red.

Note my use of "custom" setting.

Re: Rendered "Sections" in black-how to?

rob2218 — Wed, 02 Mar 2011 19:06:37 GMT

that's exactly where I looked. it was already set to "black paint"...

Now...do I have to set it to something else, then reset it back to "black paint" and re-render???

Like I said.....the rendering is coming out as I have shown in my image below.....it's not "black" the section cuts.....it's "white-ish" color.

Have you re-built the 3D view?

Re: Rendered "Sections" in black-how to?

vfrontiers — Wed, 02 Mar 2011 19:17:27 GMT

just to emphasize... You did CHECK the CUSTOM button, yes? You can change the material and still have the USE ORIGINAL MATERIALS selected and that's what you get...

Maybe my arrow wasn't big enough.

Re: Rendered "Sections" in black-how to?

vfrontiers — Wed, 02 Mar 2011 19:30:45 GMT

Both of them were HUGE...

But I just picked up on Rob saying I changed the material and didn't here I checked the button...

From my own experience with the forest and the trees, sometimes an extra highlight helps...

It's pretty cool how you can whip together a quick "tutorial" like that...

Re: Rendered "Sections" in black-how to?

rob2218 — Wed, 02 Mar 2011 19:41:56 GMT

the "custom" button is checked.
the "black paint" is checked as well........

what other button do I need to check to make the section cut plane come out as "black paint" color????

Am I missing something here that is just to darn obvious and right in front of me???

(Apologies to Rob for going slightly off-topic!) (Mini rant alert!)

I've often wondered why the controls for the 3D cutting planes and marquees are not lumped together in the same dialog box. It would make much more sense then the current arrangement of hiding stuff in unrelated dialog boxes, which only causes confusion and makes the workflow awkward!

Why have the info bar for the marquee tool only allowing you to change the shape of the selection, and primitive control of the storeys it covers?

Why are the controls that allow you to choose whether elements display inside or outside the marqueed area found in the 'Filter Elements in 3D' dialog?

Why are the controls that select the cut material of marqueed elements found in the '3D Cutting Planes' dialog?

It would be nice in the future to combine the features of both 3d cutting planes and marquees into one tool, that allows you select and easily adjust clipping volumes and planes both in plan and 3d. There is probably a wish for this already somewhere!

Rob,

In the materials dialog box, check the lightworks preview and settings for the black material you are using. Maybe it's set to render as white, or is very reflective or emissive or something strange. Does the material render correctly if applied to the face of a normal wall?

Re: Rendered "Sections" in black-how to?

rob2218 — Wed, 02 Mar 2011 21:36:44 GMT

I've checked all the settings you have all mentioned.....and still when I create a viewmap, assign it a layer combo, and try to render it.....the part of the rendering that is "cut in section" (that plane) renders light....again I am using the Lightworks engine to render.

I've checked my material settings as well and it just wont render "black".

Here's the plan I get (see image attached).
I'm sure I'm missing something. I just can't seem to get the "section cut plane" in black.....period.
