====================================================

Fixed and known issues in the latest version O/26.0

Important Information:

Important:Version O/26.x does not support the Thales run-time version 10.xx. Please use the Thales drivers provided by the Optitex installation Package. IF you installed Thales run-time version 10.xx, and are facing licensing problems, Please contact Optitex Support to fix this.
The keyboard shortcut to delete selected 3D object, has been updated from Shift+Delete to Ctrl+Alt+Shift-Delete
During the installation process, a restart may be required, depending on the Windows version and Microsoft redistributable packages installed on your computer.
Always keep your Nvidia driver up-to-date.

With the recent Nvidia card rendering speed improvements, we also set the default 3D window rendering mode to be Photorealistic instead of Interactive. This will assure that what you see in the 3D window is what you get when rendering final images. Photorealistic mode performs complex recursive Raytracing creating completely realistic 3D scene representation. Interactive mode sacrifices quality for speed by performing some shortcuts. You can still switch to the interactive mode by pressing “I” in the 3D window. Recent generations of Nvidia graphics cards also allowed us to increase maximum image size for Photorealistic (Enhanced) rendering to 8k.

Note: Renders Higher than 2k would still take longer than 1 minute, depending on the graphics card.
They should be used sparingly for high print generation only and on some older cards it may lead to “out of GPU memory” card error that would require PDS restart.

If you encounter either: View Fabric (pattern displayed on the desk) cannot be turned off and 2D actions are hidden. Or: After exporting to 3DDI, all pieces disappear form the desk and only reopening the file brings them back, the solution is in the Nvidia settings:
1. Open the Nvidia Control panel
2. Under 3D settings, select Manage 3D Settings
3. Select OpenGL GDI compatibility
4. From the dropdown menu select Prefer Compatible
This should resolve the problems described above.
To ensure that the HQR and PR3D rendering engines work properly in Runway Viewer/PDS-3D applications, you need to configure the Nvidia settings as follows:
Open the Nvidia Control Panel -> select Manage 3D settings -> select Program Settings tab -> click the "Add" button -> select the "Browse" button ->select "Optitex folder (C:\Program Files\Optitex) ->Select the "Add Current Folder" button then click OK.
Click the "Apply" button in the main dialog.
The new 3D Sample Pack does not include additional Vizoo, Swatchbook and JML materials (shaders).
- Customers with valid Annual Maintenance Contract (AMC) can get a collection of Swatchbook, JML and Vizoo materials in the Optitex Asset Portal.
- To get access to the portal, E-mailsupport@optitex.com, ask for Asset Portal access and provide:

Company name, your license key number (five digits), your full name, your role and your e-mail address.

To use the enhanced material appearance in Photo Realistic Rendering (O/21.1 or later):
- Make sure to use the shaders' material directory which is provided as part of the installation.
- If you use custom materials (shaders) previously converted from Vizoo(U3M), you need to re-convert these materials using the enhanced Material Converter.
Avatars reminder: avatars that were created in older versions, may not work properly in version O/19.6 or later. To be able to use older avatars properly, users should do one of the following:
- In the Avatar Editor, copy the sizes from the old avatar to the new one (click here to view more details)
- In the Avatar Editor, manually adjust the avatar to the desired size, according to the old avatar.

End-of-life notice for 3D Revu

As of version O/23.2, Optitex is removing Revu from its portfolio. In this new release, Revu is no longer available.

Instead of Revu, our customers are encouraged to use O/Cloud, which provides a more modern collaboration solution for 3D.

ID	Summary	Workaround
PDS-3D
TD-16497	Loading an oaff file (Optitex Avatar Framework) while not logged in to O/Cloud Link, generates "Server Busy" message and hangs PDS.	Make sure you are logged in to O/Cloud Link before attempting to load an oaff file.
TD-16496	STL file format cannot be loaded	Use FBX or other supported formats
TD-15709	Move Texture tool is not working properly on the converted materials	Use Shader Attributes in 3D piece properties
TD-15613	Wrong glTF export while texture is not applied to pieces	glTF does not support transparency or diffuse for pieces where the texture is not assigned. Assign white images as a texture, and set transparency to 100%.
TD-15583	IR mode does not work when cloth is opened from *.clt file	IR mode is applicable only when the PDS+3D file is opened
TD-15543	GLB: Texture applied to visual stitch at variant level appears flipped on symmetry piece
TD-15467	Texture "bubbling" in PR3D when materials with alpha are used	Create a back mesh shader, assign all pieces to this shader, set shader to have Transparency of 100%.
TD-15379	3D cloth is not always saved within PDS file when the file is not stored locally	Copy the data (files) locally and work with the local data
TD-15415	Images generation issue when PDS file name ends with a space character	Avoid using empty space at the end of the PDS file name
TD-10927	Binding does not mirror placement properly on paired pieces	You can have the same binding twice with and without a button. If binding contains a button, button location serves as an anchor point. If binding is not defined with a button - its anchor point is the center of the binding profile. You can create these items without a button and then import these items via seam and stitch manager.
TD-14934	Default model views changed in O21.0 compared to previous versions	Open the model in Avatar Editor O21.0 or later, click the front view icon, then save the avatar.
TD-15199	Old custom views may not look the same in O21.0 version	Recreate new custom views in version O21.0 or later
TD-15317	Custom views from previous versions may cause wrong views in the "4 views single image"	Select "Front View" before opening the Save Image dialog
TD-10454	Default size is not kept after saving the avatar in some use cases	Re-define the desired size as a default and re-save the avatar
TD-14825	Old Visual stitches textures do not appear correctly when opening files created in previous Optitex PDS versions	All visual stitch textures should be rotated 90 degrees in the Shader Manager to display them correctly. This is following the improvement in Visual stitch functionality to display them in real size and according to baseline, matching the textures display. To rotate save fbx from shader manager, rotate in image editor and then re-load the rotated textures in all Variants and Articles. Alternatively rotate all visual stitch textures in shader manager by 90 degrees to be horizontal.
TD-14619	Wrong initial position of "Arm" location for pieces within the same group	To synchronize group pieces, select all the group pieces and then press Synchronize. Their Cylindrical Percentage also need to be changed together, because they are a group which acts like one piece.
TD-14404	The location of the 3D Move/Rotate tools is far from the selected piece	Some old avatars created in earlier versions with mating lines based on STEP format have a little patch that offsets avatar center. You can delete this patch and it would fix the problem. In version O/19.6 or later, in Avatar Editor, select the patch by LMB+Ctrl, delete selected patch by Shift+Del and save the avatar.
TD-14866	When switching sizes in Avatar Editor, operation takes time
TD-14860	Following save as FBX file format, segment shapes that have a "Flip" texture attribute may appear corrupted in the 3D window.	Click "Update now" to get segment shapes appear correctly in 3D window.
TD-14856	Clicking default button when Automotive industry selected, does not select "Use Regular Tessellation" property	Select "Use Regular Tessellation" property manually and click "OK".
TD-14839	PDS crashes when Bending field is empty	Use always 0.01 as a minimum value.
TD-14745	Button turns black in HQR if it has texture applied to it	Use OpenGL & PR3D rendering engines to visualize the garment.
TD-15190	Pieces exported to the 3DDI with a "Fixed" point attribute (was used for Modulate), lead to wrong texture coverage in the 3DDI plugin.	Review all pieces' points, remove the "Fixed" attribute, re-simulate the pattern, then re-create a new 3DDI pack.
TD-14326	Avatar disappear from 3D window when dressed garment is saves as	Avatar should be opened in Avatar Editor and saved as... with a name that begins with letters, not digits
TD-15747	Illustrative Rendering is not working when the Optitex 3D Revu application is installed	Uninstall both, Optitex 3D Revu and Optitex Full Suite, then first install Optitex 3D Revu and then Optitex Full Suite.

PDS-2D
PDSD-7807	Fabric color set in Preferences is not saved	Avoid using square brackets for fabric names
Marker
MARK-4409	Buffer type in the piece properties does not reflect the proper type if more then one types applied via "Edit Piece Buffer" dialog.
O/Cloud
VDC-7854	PDS files with Shader material 'Plain Woven' can't be opened in O/Cloud 3D Viewer	Don't use "Plain Woven" material in PDS if you upload files to O/Cloud
VDC-7697	O/Cloud Link doesn't open on top after clicking continue button in upload to O/Cloud dialog in 3DDI	The icon in the taskbar starts flashing for 5 seconds and the notification number shows "1", then the icon is displayed in yellow color until you will open the O/Cloud Link. Click on the flashed icon to open O/Cloud link.
