Re: Vertex Colors (Weight Editor) in 2015
I wouldn't bother with a grid data object. Make a non-modal dialog with a color selector with an "Apply" button. When clicked, the selected polygon nodes are modified. Quick, easy to code, and scales well. Vertex colors are coded according to the data type parameter specified in the vertex color property. In the old days the default range would be integers in range [0...255], but somewhere around Softimage 2011 the default was changed to floating point [0...1]. Matt Date: Tue, 17 Jul 2018 20:16:42 +0900 From: Martin Yara Subject: Re: Vertex Colors (Weight Editor) in 2015 To: "Official Softimage Users Mailing List. Thanks Matt. Actually the problem with the Weights Editor is present in 2014 too. We can't increase 2013 licenses, so we are considering moving into 2015 but we have this problem with the vertices colors. And it seems that it will be impossible to solve it. So I'm starting to create a cheap Weight Editor version with just scripting to test if I can get better performance before trying anything in C++. So I made a grid data to emulate the Weight Editor grid and made the last cell a “color” cell. Now I'm not sure how to change this color. I think it wants a RGB888 code and I'm don't know how to change RGB values that the Vertex Color gives to RGB888. A little help here please? Martin - About the grid color, No, it wasn't RGB888 and it's not RGB565, or hex, or 10bit either. I'm lost. Martin On Tue, Jul 17, 2018 at 8:17 PM, Martin Yara wrote: -- Softimage Mailing List.
