3D-Coat version 3.3

3D-Coat v3.3 featuring Ptex support released

- Ptex is a texture mapping system developed by Walt Disney Animation Studios for production-quality rendering. Its main features include:

- No UV assignment is required! Ptex applies a separate texture to each face of a subdivision or polygon mesh.

- The Ptex file format can efficiently store hundreds of thousands of texture images in a single file.

The Ptex API provides cached file I/O and high-quality filtering - everything that is needed to easily add Ptex support to a production-quality renderer or texture authoring application. (Sourced from http://ptex.us).

Ptex technology allows you to increase local texture resolution on selected faces, so you can achieve a high level of detailing on a very tiny part of the mesh:



3D-Coat allows you to paint your assets with this new Ptex system and simply export textures in specified Ptex file format or as a simple texture to render in your favorite render engine like you normally do with UV-set based textures. Thus, you can get absolutely seamless textures!




General changes:

- Special simple method for external programmers to make connector between 3D - application and 3D-Coat has been done (Description).

- Possibility to create/install 3d-coat extensions from File menu. Extension may contain any sort of files - shaders, pens, strips, materials, masks etc. It is just an image of additional files in 3D-Coat's folder. It is a good method to share 3D-Coat's content. The first extension pack was made due to Oliver Thornton! (Download the Pack)

- Possibility to upload screenshots right from the 3D-Coat onto the web server. It is very useful for sharing your experience with the community.

- Framing improved - you can focus on object or on pen position (scaling depends on radius in this case).

- Text information about current viewport - front/back/left/right.... is being displayed now.

- Now you can assign several actions to the same hotkeys combination. Actions will be performed in consecutive order after each next activation.

- Improved 3DConnexion support.

- Fade on edges in pen options will act on all pens simultaneously.

- Support of big 3B files to open (>4GB)

- Lots of bug-fixes and small improvements.

Paint Mode changes:

- Possibility to pan in texture view with SPACE as in Photoshop. You should choose 3D-Coat preset from [Camera] menu.

- Drawing with CAPS LOCK will hide cursor only while painting, not always. It improves precision of painting and gives better control.

- "Frame" command will move pivot point to the center of the object (and framing itself of course) in custom pivot point mode.

- Much better correspondence between Voxel room and baked color in Paint room.

- Support of multiple SL objects in a scene.

- Splines/Lines in E-panel will not dive into surface in paint room. In such a way you can easily draw over curved surfaces.

- Much better algorithm for limit subdivision surface directly after importing model for microvertex painting and Ptex. Model after import will look much closer to the limit subdivision surface.

- Better padding for PSD files export.

- Normal-map strength in per-pixel mode can be corrected with Depth modulator slider in layer blending panel.

- Eraser will lower normal-map strength when applied over the normal-map layer.

Retopo Mode changes:

- Quadrangulation quality and speed improved.

- In Retopo->select tool Relax will act only on vertices selected in Retopo->Select->Verices. Snap button will work in the same way.

- “Turn off snapping” button in retopo tool.

- Snapping essentially improved! You may choose one of 3 methods of snapping: outer, nearest along normal, absolutely nearest.

Voxel Mode changes:

- New Measure tool in voxels:

It allows to measure and define everything in Voxel Mode using physical units like inches or meters. It is extremely useful for real production and prototyping.

- Improved 3D grid. It can be customized to work with real units. 3D-Coat will fit much better for precise works:


- Voxel primitives will follow grid points while moved with SHIFT (use CTRL, CTRL+SHIFT for smaller step of movement).

- New Pick tool for voxels. It is very helpful if you have many layers and want to select current object visually without VoxTree:

- Lines/curves in 'E' panel will not dive into surface in Voxel mode.

- Improved cylinder-like manipulator.

- Selection opacity slider was added to pose tool.


We hope you enjoy this new release!
