[Solved] VDM brushes in 3DCoat

I asked Andrew about Vector Displacement alphas as well, a few years ago. It's a better solution than the ON PEN option in the IMPORT tool, especially for repetitive objects like scales, spikes, teeth, etc...as you can apply many with a single brush stroke (using spacing) and you have better control using the Stamp Draw modes.

Was added as an early release on 3DCoat-2023-11 
 
- Preliminary (early stage) support of VDM alphas in Surface/Extruder tool. 3-channels, 32 bit EXR-s are treated as VDM-s. Later it will be extended (picking VDM-s from any raw surface, color, making VDM from any model, support VDM-s in voxels and in all brushes). All this is in gradual development, exposing just this small piece.

Not yet since it is being developed, but the process is simple. Create a new folder in Brushes where to load 32bits exr vdm alphas.

Select Surface mode > Extruder tool

Paint or stamp over the mesh.

On Tool Option panel subdivision is helpful to add located detail and avoid to add res+ to whole mesh.

The Pick & Paste Surface Sculpt Tool, located near the Extrude, allows you to grab a feature from a raw surface, create a Vector Displacement Map (VDM), and use it with Extrude to duplicate the feature.
It doesn't require a flat or nice surface to grab the element; it automatically unwraps and flattens the edge.
You can also export VDMs as EXR files to use in other applications.
Additionally, you can add external VDM alphas (3 channels, 32-bit, EXR/TIFF) into the Alphas panel and use them in the Surface Extrude.

Carlosan, I have 3DCoat 2023.19 and I do not see the Pick and Paste tool.  I went back to 2023.11 and could not find it there.  Could tell where this tool is located?

Try Reset to default settings

您需要导出ZBrush VD 地图才能将其导入 3DC。

I use many VDM brushes in Zbrush, but I really want to use it in 3dcoat. How can I easily export the VDM brushes in Zbrush to an EXR format that can be directly applied to 3dcoat? At present, I can only convert the brush to an OBJ model in Zbrush, and then use the Pick&Paste function in 3dcoat to convert the model to VDM brushes supported by 3dcoat. Is this too troublesome? Do we have a simpler way to obtain brush formats supported by 3dcoat?
