creating seams in materials, reflections


Recommended Posts

Hi All


I have three questions...y'all have been so helpful, so I give you a 3 for one deal today!


1) I am trying to create seams in hardie siding.  I have attached the reference photo (grey area).  The Hardie material is already in the catalog, and it "paints" well with no seams, which is usually how I prefer, but in this case I need to create the seams and see each individual panel.  I tried to alter the material definition, and I created a new material with a border but both didn't work well. 


2) Also, this same photo shows cedar panels that are thicker than the Hardie.  The cedar is on it's own floor, so these areas are already separated by floor.  I tried having a thicker wall type but the walls were skewed (one jutted out).  I see in material definition that there is a thickness area available,but it doesn't seems to change visually.


3) Finally, the windows in the photo are really reflective.  I like this effect.  I am not seeing this in my ray trace so (after a suggestion from tech support) I put a polyline in front of the building and painted a backdrop to give the windows something to reflect but it didn't work so well.  Then I had to learn about refractive index from Wikipedia, and I  had to take a nap.  Can I get the windows to reflect more?  Water is more reflective than diamond? Or vice versa...


Any suggestions?

Thanks in advance

1) to get the seams correct, you'll need to do virtually what the siding installer would do...cut and install individual pieces! Material regions or p-solids. Not what you wanted to hear but I've been there.

3) window reflections are the source of my premature grey hair! Trial and error...

As for the Cedar it will depend on the Wall definition and how the two walls Align ...they usually Align over the "Main Layer Outside" , ie usually the Framing , so just making the wall thicker won't work unless you "resize about Inner Surface" perhaps. ( Alt-Q Shortcut key)


Will they be aligned in real life? (RL)  if yes then build your wall layers as in RL, ie the Hardi will be mounted on 1/2 thick Treated Battens usually (Rain-screen) , there should likely be a Flashing detail between them too.


I hope your Client realizes Cedar requires ALOT of maintenance , it looks great for the 1st 2-3 years but tends to take a beating with UV, Rain etc as it can move dramatically in different weather conditions.....

I agree looks great.  I downloaded but can't find it in my user catalog...I also downloaded RL-inc's metal panel and it showed up in the user catalog... any suggestions?


But I had JUST finished making my own panel and then this reply came in.  I did a combination of wall material regions (multiple copy including a gap) and then took a snip of this in PBR, and used as a material to paint entire exterior.  Then used wall material region for cedar to make thicker.  I think turned out pretty nice, but now I would like to try rlacklore's panels....


As always, great help here.

They should import - don't know why they wouldn't. Here are their names:



Thanks again Robert , looks good , they imported fine here to my User Library


( they aren't in a HardiPanel Folder Melissa, if that's what you looked for? )

      Hi all,
      All mirrors from the catalog(s) that I am placing show a bright yellow cast and pixels on the reflective surface of the mirror itself. The mirror IS reflecting the room around it, but the bright yellow color and pixelation never resolves itself. The first photo is the 'Standard' camera view rendering technique, where the yellow is at its brightest. The second attachment is 'Physically Based' rendering technique, where the yellow is faded a bit.
      I had no problems in X10, but this issue has been in all of my plans so far using X11.  
      Any thoughts? The mirror material is set as a 'Mirror', with 100% reflection. I've not changed any defaults, preferences, or qualities about the mirror material or camera views that I could think would affect the reflective quality. Help appreciated.

      Here's a couple.

      So I'm a bit upset with this new update. Maybe someone can help me here, but have they removed the reflection option from the material class? One of the greatest features CA had when it came to ray trace rendering was the ability to add a reflection to any material. I found it handy for adding to granite countertops, floors, and even backsplashes etc. for ultimate lighting/realistic photo quality renderings.  I just installed the beta x10, and went to material definition as I always do before a ray trace... and come to find out NO reflection category at all now. While there still is a mirror setting, shiny metal, and polished category, there is no longer the ability to adjust the reflection of a material manually without changing to a metal or mirror preset (which normally turns everything black). The new physical based rendering does seem to add a reflection to a few materials such as granite countertops, however its extremely upsetting that I no longer have the ability to adjust manually.. Please CA bring this back or I will be stuck using x9 and losing out on all the new features, or please explain what I can do to have the reflection option back. Thanks...

      I can not get my mirrors to show reflections. The material properties are set to "mirror" and the camera is set to show reflections. I am in a 3d perspective view with standard rendering technique. Are there other settings that I need to change?

      Anyone have any ideas as to why my mirrors reflect everything in a blue tint?
