Blender-color sample picker selects wrong color in vertex paint mode.

melviso

So I have been experimenting with Blender for texture painting workflow. Just noticed that when I right click to sample color, the color selected is a darker color. This happens when I try to paint in vertex mode. Texture mode painting samples color fine. Is this a bug or is there something I am doing wrong? I am using Blender 2.78 released on 26/09/2016.

Thanks.

dunno, try to report it

I think I figured it out. Set viewport to material mode and in the material window, tick shadeless and vertex color paint, that way, the colour picker samples only the color information. I seem to be getting a lot of lag from vertex painting the default cube to which I have subdivided to get high res texture.

I am looking at a workflow where I can handpaint with vertex color at very high res density and then bake to texture for a low or lesser poly mesh. The advantage is you can bake at 16 or 32k textures. I am not sure Blender can handle this? ZBrush seems to be the only app that can allow fluid vertex painting of very dense mesh and bake to 16 or 32k textures? Another advantage is the vertex textures go with the mesh file so u can always revisit the file to re-paint stuff without having the file textures in a different folder.
Is there a way to optimise vertex painting to avoid lag in Blender? I do have 3dsmax open while vertex painting in Blender.

https://blenderartists.org/forum/showthread.php?405772-Polypaint-in-Blender!-Its-happening-D take a look here, it's still experimental but it seems to add lot of possibilities to vertex painting in Blender (mirror painting, performance etc.)

Thanks for the link, yadoob Downloading it now. I feel vertex painting is quite a good workflow. You concentrate on the details resolution independently and bake to high res textures. Will see how it goes compared to using viewport canvas or photoshop.

Yes, true, I like also the vertex painting but Blender has some limitation and not so much dev in that side. Maybe you will be interested in few tool I add for personal workflow such as vertex group selection : https://www.youtube.com/watch?v=D2yZJpOs6SA

Thanks yadoob Btw, is there a way one can sample color with shading on? I am beginning to suspect this might be a bug. I can only sample the true color with shadeless ticked in the material tab.
