Scorelines...

[jtiscareno]

To get scorelines on buildings or on the sidewalks I had to do an actual 3d long and narrow box and then extrude it from the wall or the sidewalk. Modeling in AutoCAD.

 

I ran into Imprint and tought that this might work with just imprinting the 3d lines of the scorelines and then be able to see them in the final rendering in Viz.... Ah but life is never that easy, I tried it and nothing, nada, the imprint worked but when I load the model in Viz I can not see the imprinted lines.

 

Am I doing something wrong with this procedure? And Is this or my other method the only way to do exact scorelines?

 

Thanks

whats a scoreline? we probably got a different term for them in the UK

I think he means joint line. If so, you should create it in the material.

[Jeff Mottle]

Depends what rendering engine you are using, but I've had all kinds of grief trying to get small joint lines in building facades to show up. Especially if you are using GI. It's a catch 22, becuase to get enough samples to have modeled score lines show up you kill the rendering time of the rest of the image. Antialiasing also play a role in this dileama as well. It will probably be easier to use a bitmap with alpha to pull this off.

are you doing a boolean subtract = imprint?

 

i usually make score lines (reveals) on a separate layer

give Them a dark color in autocad no material in VIZ or

 

add The material in VIZ

 

but Then move Them UP just .125" or so above The concrete flat

or move Them OUT just .125" or .25" from a vertical wall or siding

 

This will give you a "shadow" because of The dark color of The material

 

creating The Score Lines on a separate layer allows you to modify Them later

and also leaves The original layer of The Wall or The flat surfaces still intact

 

This avoids using booleans, Totally

just an Idea

Coursing/Joint lines are extremely important in my office with grout/joints being tested 1/2 vs 3/4 etc. I avoid maps because we often have slight variences in panel modules.

 

I use brazil R/S, so this is how I do it.

All joints/grout lines are lines. I render them as 3D squares. Disable shadows, disable GI, and have them self Illuminate at around 50%, and make them the right color. This way i can define exactly how big they are.

 

for quick stuff I use maps, but for detailed work 3D lines..

[jtiscareno]

Randy tried your trick but it is not working, I even tried giving them .125" thickness and nothing.

 

Joseph looks like you are on to something but sorry to ask such a question, but how exactly do you render the lines as 3d squares??? Are your lines just typical lines in cad? And do you move them up or out a small distance or are they right on the sidewalk or walls??? I am using also brazil or vray depending.

 

Thanks to all, dont know exactly what "scorelines" translates to England but they are not joint lines. Joint lines are what the word says, scorelines are usually made in eifs or stucco for expansion and contraction and also just for looks and we use them a lot in my office.

If you've got VRay can't you just use displacement? I know you can do this in VRay, and Brazil must have a way to do it too - make a map (bitmap or procedural) that's got the score lines drawn in a white or gray on a black background (and drop the blur value), and in the VRay displacement settings set the amount to a negative number - the lines will be displaced "down" while the black stays in place. The displacement will also be used in the lighting solution, and you can make some surface features by displacing one surface through another like in this crude hack of an example with 2 planes, the red one is below the gray one with a tile map displace, note that shadows and GI worked:

 

[jtiscareno]

AJ that is also a great trick, but I need something simple like what Joseph says and also loved the idea of having the scoreline layer as separate so if needed I can readjust them if it changes...and you know this never happens...

 

I have made them work, I trun each line into a Pline and give it a widht, then in Viz I truned them into a mesh a voila! it works.

 

Thanks to all and please if you have others ideas or techinques please post them.

AutoCAD right.. This is one way:

Import your joints as a seperate layer, under the import options group them by layer. then under the editable spline properties click renderable, 4 sides, and the size you want it to be..

 

 

see image.

[frank1331]

In ADT I just use massing elements and subtract them from the wall. Should be similar in basic AutoCAD. Just do a booleen.

 

I have always had over-exagerate the depth of the joints in order to get them to show up. So, a 3/4" reveal is now 2" (depending on how far away the rendering is). It's not necessarily correct model wise but its a work around, and most people wont even notice the difference.

[John Dollus]

You could also model your walls complete, use the slice modifier to create edges where you need them. Go into subobject mode after that and run the make lines from edges with no interpolation. That will give you splines that follow the contours of the building and you can then make renderable.

I usually render them out as a seperate layer and comp them in combustion for video or Photoshop for stills.
