Member dulo Posted September 20, 2011 Member Report Share Posted September 20, 2011 I would like to select Voxel Blobs. Is there some possibility to do so in 3D Coat ? The code should be there. For Autoretopo it should be essential to find Voxel Blobs/Islands. thx for help and tips dulo Quote Link to comment Share on other sites More sharing options...

Thats not exactly what i need. I have a complete skeleton from an MRT Scan but I have to retopologize each Bone seperately to get proper Meshes. Often its really hard to split the tiny bones in seperate layers to send them to retopo. I would need a tool to select connected voxels which would in most cases select one complete Bone. At the moment I am working with the hide and split hidden tools but they are quite tedious for this task. I think that the logic must be implemented in 3D Coat because this Blob search is needed for autoreptopo. Quote Link to comment Share on other sites More sharing options...

Its not possible to do this in 3DCoat already unless each obj have different material IDs, then when merging you can check "merge to separate volumes" box.If its only one material ID you need Zbrush for this. Here is how to do it in Zbrush. 1)Import .obj. 2)in Polygroups palette use Auto-group. 2)in Subtool palette use Grpsplit. If you dont have Zbrush here is how to do it in 3DCoat, you will still need to use split tool on each objects ,but its gonna be easier,no hide tool. 1-Select Pose tool 2-Change pose mode to "select object". 3-click on 1 bone 4-Select Along X 5-Enter in "direct move" a value of 200 (or any value that will move object far away from the others) 6-Now use Split tool on that bone. 7-Redo step 1,2,3,4,5 but instead enter negative value (ex:-200) now object will be back at original position. Repeat for all bones....Good luck. Quote Link to comment Share on other sites More sharing options...

The Cell/Hide stuff doesnt seem to work for me. It just hides the voxel cells i select but not the connected voxel cells. I tried with both stamp tools from the E panel. But again thanks a lot.

I will give it another try but yesterday it didnt work with double click .. and it would be very handy for those tiny hand and foot bones !!!
