  1. The texture map controls (placement, scale etc) are formZ parameters so they are used by both RenderZone and V-Ray for formZ (and shaded work/full of course). 

    Renderzone inherits the the basic material parameters (diffuse color, diffuse texture map, bump map etc) from V-Ray materials. Materials that use these parameters (Generic, Car Paint etc) will appear very similar in Renderzone.  If your V-Ray material uses a VRMAT material or other non image based parameters (reflectance, refraction etc), then RenderZone will show a approximation of the material.

    This works both ways so if you have RenderZone materials, V-Ray will inherit the basic material parameters (diffuse color, diffuse texture map, bump map etc) from RenderZone.

    Keep in mind that there are many other factors that affect the rendering including lighting, environment, global settings etc that its not realistic to expect the engines to give the same results.

     


  2. Andrew,

    While displacement creates a nice rendering effect, it's weakness is edge conditions. The object's normals affect the displacement. To create the hard edge of a cube, form•Z will split the normals along the edge (ie one pointing in each direction of the adjacent faces). This will also be reflected in the displacement as you have observed.
     
    The workaround is to make the entire object render as smooth (Attributes->Smooth Shading->Facetted Objects->All Faces). See attached UI and resulting rendering. Note that there still can be slightly “roughness” where the patterns align unless you have a pattern that is designed for alignment (like the second example).
     
    The displacement uses the object's texture controls. A technique for setting up the mapping is to make a material with the diffuse texture that uses the desired displacement map. Use the texture tools to set the mapping type and parameters. If you do not want to use this material for the result, then assign a different material to the object once the desired mapping is established.
     
    We are consulting with Chaos Group if there is a way for us to have separate normal channels (and UV texture channels) for shading and displacement which would allow us to automate this behind the scene and give the desired shading across the faces. We will also be adjusting the UI to allow for a negative displacement amount. This might create better results in these cases.
     
    We hope this helps!

  3. Thanks for your interest in V-Ray for formZ. You should experience excellent results with this hardware!  With V-Ray you can choose to use CPU, GPU or both (hybrid). V-Ray for formZ will use all of the hardware resources available. You can also choose which resources are used if desired. 

    V-Ray is licensed per render instance, not per processor or cores. That is one V-Ray for formZ application requires one license which can use all of the hardware available to render.

    If you want to perform a second rendering simultaneously within the same application instance (ie open a second project while the first is rendering and render it with V-Ray) then you can add an extra render node to your license. Render nodes can also be used for distributed rendering on machines on your local network. V-Ray uses a online license server that allows the licenses to be shared within your organization. 

    Does this help?


  4. Clones can be transformed "individually" or "as a family". This is controlled by the option in the transformation tool options. "Individually" apples the transformation to each clones instance about its own local axis and the "as a family" option is applied to the while family as a set. Changes to a parameter of a clone are propagated to each instance individually. 

    What we have observed is that in v8.6, the dynamic display during the transformation always functions "as a family". Once the final click of the transformation is made, the transformation is applied each object when the "individually" option is selected. See images

    We have logged this aa an issue and also have added suggestion to be show if an object is in a clone in the information tab (and how many siblings it has).

  5. As suggested, please check if the Frame buffer Force Color Clamping option is on. If so disable it. Does this help?
     
    Forces color clamping in the V-Ray VFB. Click and hold left mouse button to display the clamped colors in the V-Ray VFB.

    Save the image from the frame buffer. Does the artifact exist in the saved image?


  6. Allan,

    We are sorry you encountered a problem with formZ. Clones are a feature that has been around in older versions of formZ for years (In fact the technology is behind the scenes in v7 and v8). We re-enabled the UI in v8.6 as we had a number of request for this feature.

    The message that you encountered is an indication of a geometric or topological problem with one or more objects. As clones are really just a linkage between objects so the family can be updated when one changes, we doubt that this is the cause of the problem. As you get a similar message in v8.5 (which is blind to clones), its a indication that the clone linkage is not itself the issue at hand.

    The support team has answered your email and hopefully we can get the root of the issue.

     


  7. We just completed an update of the forum with new software and a new host. All of the problems of the last few months should be resolved and you should notice the its more responsive and looks better too! If you experience any issues with the new forum, please click "contact us" at the bottom of the page and send us a note. Sorry but posts from the last 24 hours may have been lost in the transition, please re-post.

    Thanks for your patience, we think it was worth the wait.


  8. We are pleased to announce that formZ 8.6.3 is now available for pro, jr, free and student editions.

     

    If you are using v8.6.2 or v8.6.1, you can update you installation by selecting "Check for Update" from the Help menu within form•Z.

    If you are using v8.5 or v8.6.0 (or if you experience issues with the software update feature because of a firewall or other connection issue), you will need to install from here:
    Click Here for formZ pro.
    Click Here for formZ jr.
    Click Here for formZ Student Edition.

    Highlights of enhancements in v8.6.3:

    • Large STEP files now open properly on OS X.
    • Selecting “Group/Component Complete” while editing a group or component no longer crashes on certain systems.
    • Performance of switching between graphic windows has been improved.
    • Performance of switching between form•Z and other applications has been improved.
    • Image files used as textures are now updated in the graphics window and material parameters when the texture is externally edited while the form•Z project is opened.
    • Auto save is no longer initiated immediately when a file is opened or a new file is created.
    • Animation using RenderZone on scenes where the camera (view) do not change no work properly.
    • The mouse scroll wheel no works properly on certain Windows versions.
    • Group override materials are now copied properly between projects with "Copy & Paste”.
    • Components that contain layers with override materials or groups with override materials now work properly.
    • Printing with extents selected now properly fits the page for non-perspective views.
    • Printing Notes and dimensions is more accurate.
    • Picking/pre-picking certain geometry no longer crashes.
    • A new option “Remove Duplicate Materials” has been added to the materials palette context menu. This will remove materials with identical parameters (except name). All objects/faces that reference the duplicate material will use the remaining material.
    • Selecting "Purge Unused Materials" from the materials palette context menu no longer removes materials used in Group overrides.
    • Snapping/picking of arcs or objects with circular/elliptical edges much faster. (Most noticeable in files with a significant number of these shapes, specially ellipses.)
    • Texture image files that are 65K in size now properly work with distributed rendering.
    • Subdivision objects now inherit face colors from the original mesh/cage.
    • Collada (DAE) import now loads the materials and UV’s properly.
    • Notes now import from DXF/DWG files with the proper placement.
    • Other various optimizations and stability improvements.

  12. We have observed this can happen on certain combination of machines and operating systems. 

     

    This issue has been fixed in v8.6.3 which we expect to release by 8/15/18. We have a pre-release of v8.6.3 (pro) that we can make available if you are interested in trying it. Please email support@formz.com if you are interested in testing with this pre-relase version.


  13. We have observed this can happen when generating Renderzone animations where the camera is not animated (ie only objects/lights etc are animated). You can trick the animation generation by key framing the camera (it doesn't need to actually change, it just needs to be key-framed so its updated by the the animation engine).

     

    This issue has been fixed in v8.6.3 which we expect to release by 8/15/18. We have a pre-release of v8.6.3 (pro) that we can make available if you are interested in trying it. Please email support@formz.com if you are interested in testing with this pre-relase version.


  14. All,

     

    We currently have no outbound email from formz.com. We are receiving emails, however we can not send responses. We are working on addressing the issue and expect to be functioning again later this afternoon.

     

    Thanks for your patience.


  15. As Des points out the Object Doctor does not see this as an issue because it could in fact be intentional.

     

    There is another workaround when these issues occur that can be useful in a mode complex model where it snot so easy to reconstruct: remove the offending edges (which removes the adjacent faces), reconstruct the complete face from the adjacent boundary and stitch in the new face.

     

    Here are the steps we used: 

     

    Pick tool: set the topological level to segment. Pick the two "extra" edges.

    Delete Tool: click in the window to delete the pre-picked edges.

    Pick Tool: set the topological level to segment sequence. Pick on one of the now open edges and select the sequence of edges.

    Derive Segments tool: select the Join Selected Segments option and click to make a wire from the segment sequence.

    Cover Tool: select the wire object that was created and cover it.

    Stitch tool: stitch the new face back to the original object where the edges were removed.

    Repeat for the opposite side.

     

    Round Tool: round the entire object (tried 3/8" and 3/16").

     

    We will investigate if this could be offered as a general tool in the future (maybe "merge faces" ).
