Member trubetsk Posted September 8, 2017 Member Share Posted September 8, 2017 (edited) Hi, I'm attempting to voxel sculpt with custom alpha as a texture I've created at 1024x1024. I'm having several issues: 1. At small radius various pieces of the alpha are missing, or have holes. It seems different with each stamp of the bruch. 2. If I increase the radius to a large size, the alpha won't paint at all. There is simply no response from the mouse click. (See attached) What am I doing wrong? I googled around before posting and found this bug: http://3dcoat.com/mantis/view.php?id=2084 which was marked fixed in version 4.5.29. I'm even using "constant pressure" mode for my brush. How do I get my alphas to look as crisp and high resolution as in that picture (on the left). Please help! Thanks a bunch!

The new version of 3DCoat 4.7.37 fixed several issues with alphas. Please give it a try. Thx Quote Link to comment Share on other sites More sharing options...
Member trubetsk Posted September 9, 2017 Author Member Share Posted September 9, 2017 Thanks I tried downloading the beta 4.7.37 client. Same problem though It gets more interesting, I started doing more testing with different brush alphas and getting different results depending on the alpha used (See Attached) I was basing this on the hunch that the brush was not working because the 'middle area' contained transparent pixels. It's sort of the case... Sometimes it will extrude the complete alpha (A & D), other times it will extrude only certain pieces of the alpha (example C) and and other times you simply get a blank result (B)!

Member trubetsk Posted September 9, 2017 Author Member Share Posted September 9, 2017 Update: I found a workaround. It has to do with filling the center hole of an alpha with a very faint transparent object. It's somehow related to alphas failing to print all or some of their parts when their center area is fully black (transparent). Quote Link to comment Share on other sites More sharing options...
Carlosan Posted September 10, 2017 Share Posted September 10, 2017 Falloff value is 0 ? Quote Link to comment Share on other sites More sharing options...
Member trubetsk Posted September 10, 2017 Author Member Share Posted September 10, 2017 It was just a parameter I was fiddling with trying to understand what might affect the alpha stamping. Falloff 0-100 doesn't change anything in this case. Only adding more opaque shapes to the center of the alpha seems to help. Quote Link to comment Share on other sites More sharing options...
Carlosan Posted September 10, 2017 Share Posted September 10, 2017 Voxels are like 3D pixels (made of clay, let's say) and are very good for creating a model that needs only surface details added. It is the preferred medium for doing booleans without errors. Change to surface mode when details are to be added (especially with the automatic tessellation used in the Live Clay tools). - Use Voxel mode for rought blocking. - Surface mode to add details - And Live Clay tools mode to add fine details, as your Alpha example need.
