i think the custom tool sdk is softimage's answer for the 'true paint system' you desire.
you mention it lacks the 'hooks to trigger feeds and pushes'. care to elaborate? there are methods of the ToolContext which allow you to updated parameters and transforms. (BeginParameterUpdate, UpdateParameter, EndParameterUpdate, etc) Amhidou started a 'live paint' custom tool. its not a complete tool without issues but it shows the tool sdk is capable of a brush tool. http://www.si-community.com/community/viewtopic.php?f=13&t=1735 s On Tue, Apr 17, 2012 at 11:29 AM, Matt Lind <ml...@carbinestudios.com> wrote: > We’ve been wanting to use the new SDK UI toolkit to create our own brush > system but I think what we overlooked is how the SDK tool kit is implemented > – it lacks event hooks to trigger feeds and pushes when we’d like in order > to provide the workflow experience that is expected.
