Imported material (JPEG) not rendering correctly in raytrace

Recommended Posts

Hi folks,

 

I have struck an odd problem I've never experienced before displaying imported materials correctly using raytrace. I imported a JPEG containing the attachedimage of white marble, and while it shows up fine in all other views (3D camera, for example), in raytrace it shows up as a red/pink colour without any of the marble detail (see attached). In this example I am using the material on a solid that was created using poly line solid then converted to a solid. I have imported lots of other materials including the timber in the background of the attached screenshot and they have always displayed correctly in raytrace until now. It doesn't seem to make any difference how long I leave the raytrace to run (this one was produced after about 90 passes – the advantages of a fast processor!).

 

Any ideas? Cheers,

Can you attach the plan (or at least the material definition as a library item)?

Is the fireplace something you've imported as well?  Looks like one of those Sketchup double-sided polygone SNAFUs

Hi Jon,

 

The fireplace itself (i.e. the flame, the box and the stainless steel frame around it) was imported from sketch up, but the whole chimney and the marble feature were created as poly line solids in CA then converted into solids.

 

I tried to attach the plan itself But it is too large (90 MB). Can anybody give me any guidance on what I should be looking for in the plan that is making the file so big? That would also account for the fact that is now taking forever to rebuild the 3D perspectives.

 

Cheers,

Hi Mark,  Give this a try, it seems to work fine for me.  If your original  .jpg is more that 96 dpi you could make your own library material with higher resolution.

Hi Chopsaw,

 

Thanks for taking the time to do that. Whatever you did to my image, you fixed it so it now works perfectly in my plan. What exactly did you do to make it work?

I did not expect it to work perfectly as there are a lot of custom settings you can tweak for Raytracing but I did get rid of that awful purple mess.  Right click on your Library User Catalog and that will bring up the "Define Material" Dialogue (The Tea Party).  Go to the Texture tab and give it a name but don't spell it wrong like I did.  Browse to where you have that .JPG file that you posted.  Set it to "Stretch to Fit" and anything else you would like to play with in Properties and you are all set to put that in your Library when you say OK.  And you can also do a quick Ray Trace test right in the DBX.

I guess I'm a little too late, I have the exact same picture for a marble texture in my custom library and never had issues with it, as much as I like the chief library I tend to download images and create my own.

      Hi everyone-
       
      In the last several plans I have created in chief X11, using a Camera View with a Reference Display of the As-Built, I have the As-Built Reference Display file set to render as a Glass House view. The Glass House referenced model displays, but without any of the dark outlines to show the features of the model. I have included an image of a remodel I am working on currently, where the referenced As-Built shows as a faint blue shape. Nothing like the examples Chief gives of a reference display, below.
      Any thoughts on what setting I might be able to change to get the 'outlines' back. I have also included an example image from Chief I found online, which has the desired 'outlines' in black.
      This does ONLY happen when I'm using Glass House View as a *Reference Display* in the plan I'm working on. If I were working on a plan and change the rendering technique to Glass House, the outlines are visible. This only happens in Reference Display.

      Is there still no material that will allow transparency in Vector View? I use a lot of glass for deck railings and its completely insane what needs to be done to make an exterior elevation drawing look decent. Currently, I need to build my railings without any glass, then build the glass manually, place on a separate layer so I can have it on in renderings, but off in elevation views (vector). Then, in elevation view, I need (choose) to manually draw p-lines with transparent fill to show the glass without blocking visibility of the structure beyond.
      I don't like fighting Chief's defaults and auto features, but I also want my drawings to have a certain appearance. Anyone have any thoughts or tips for transparent glass (not windows) in vector views?

      Hi everyone-
       
      In the last several plans I have created in chief, using the reference display in a 3D view (referencing an as-built plan overlayed onto the remodel plan) with Glass House View, the Glass House View is very transparent, with no 'outlines' around the items in the drawing.
      It makes it quite hard to see what the existing vs. remodel.
      Any thoughts on what setting I might be able to change to get the 'outlines' back. I'll attach a photo of a kitchen I'm working on currently below, showing how faint the Glass House View is, vs. an example photo from Chief I found online, which has the desired 'outlines' in black.
      This does ONLY happen when I'm using Glass House View as a *Reference Display* on the referenced plan. If I were to delete the reference display plan, and just change the rendering technique of the Plan file I'm working on to Glass House, there is no problem. The 'outlines' show as desired.

      Hi everyone, 
      Is it possible to create more then one new material at the time?
       
      I have in a folder filled with wood grain pictures (vertical & horizontal) and I would like to add them all to my library but doing it one by one will take forever... From what I see in the program, there doesn't seem to be a way yet. But I imagine or hope that someone found a way to do it.  I must not be the first user who wants to do that to save time. Any idea everyone?  Thank you.

      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.
