I have an issue when trying to texture paint an object with a stencil. Screenshot : up: correct painting, bottom : stencil painting impossible As visible on the picture, there is some kind of a black shadow over the stencil (a dark wall grunge) which prevents me from painting... If I use a normal brush (top of the image), there is no issue. May I add that taking those very same objects, unwrapping, brushes and texture on this object in another file creates no problem. So maybe it is a special issue, I found no thread about this shadow over the stencil.

Thanks for any help you can give me! By the way I'm using version 2.76

  • $\begingroup$ Why are you using a Clone brush in the top picture? A texture should really be used with a TexDraw brush actually, and it looks like in the bottom picture you have a grunge texture set to paint Add Alpha which will only show paint where the brush texture is white. Black will drop out. $\endgroup$ – Craig D Jones Mar 20 '17 at 17:27
  • $\begingroup$ The top picture to show that painting is working. $\endgroup$ – user37096 Mar 20 '17 at 18:22
  • $\begingroup$ I played with the settings a bit more, and I can use the stencil not with a TexDraw brush but with the normal brush. But only in the UV Image editor, not in the 3D Viewer in Texture painting mode !

  • $\begingroup$ In 3d view are you in texture paint mode and working on a 3d mesh object with the image as a texture image to be painted on? I can't see your settings with the cropped images, and you might consider posting a demo file with packed images to work with as examples. $\endgroup$ – Craig D Jones Mar 20 '17 at 18:59
  • $\begingroup$ Yes sorry the composition of this screenshot was not my best. Here's a blend file when i tried to recreate every step as i did on my project. I "still" have the issue for the painting. but i don't have the dark shadow over my stencil as on my first picture. <img src="https://blend-exchange.giantcowfilms.com/embedImage.png?bid=2972" /> $\endgroup$ – user37096 Mar 20 '17 at 20:57

Soften is not a drawing tool, but a tool to 'soften' the range of pixels under the brush like a blur tool. When you paint with it in the 2d editor, you are actually blurring the pixels there in the alpha and causing an error where they then appear black - but that is not a paint effect, but an error. TexDraw is the basis tool for painting when putting down color, and set it to 'mix' to put paint into a zero transparency image. By painting with that and using the image as a stencil, you will get the image into the 3d view as paint - but you really might consider instead using it as a stencil in the Texture Mask and using the alt-rmb combinations to move it around scale it and rotate it. Once you have all your pixels painted in, then you can use a Soften over any harsh edges, or push them around with the Smear to push them around to get variation... here is a screenshot of me painting with TexDraw using your texture as a mask brush set to Stencilmask brush

edit: Load up TexDraw and set it to use 'Mix' as mixing mode(default) and then delete the textures from both 'Texture' and 'texture Mask' in the brush tool bar (this doesn't remove them from blender, so you will be able to call them back up later in another brush). Select a color in your color mixer so that it will show up on the surface of your model, and paint across the surface to test - does it show up as a paint stroke? TexDraw used to be just the Texture brush, and Draw was the Brush.., but the original 'Brush' was eliminated and 'TexDraw' was kept. Soften. Smear, Clone all work only if you have pixels painted into the image already from TexDraw, and Fill also is a brush to drop color pixels into the image. Fill can be tricked into becoming an eraser, but that isn't needed here. If you can get paint into the image, then from there you can refine it - Only TexDraw would be my first option to use your image as a Brush or Brush Mask texture to paint in grunge. The Brush will paint in a Color version of the image where ever the white is, and not in the black. The Brush Mask will paint only where the white portion is, but also allow you to use another texture as Brush and create more complicated mask and brush combinations. Often times I use an image as Stencil for the Brush and a procedural like Clouds set to Tiled on Brush Mask so that the clouds chip away from the stencil organically.

  • $\begingroup$ Thanks for that. What's the "basic" brush to juste paint like with a real paintbrush (clone fill mask smear soften texdraw ?) I really tried painting as you describe, but i still have the issue : stencil unusable in the 3d view, and in my project, a dark shadow over it $\endgroup$ – user37096 Mar 23 '17 at 18:26
  • $\begingroup$ Please see my edit in my answer, and if you have any need to see it in action, let me know and I can try to put together a video. Might do that either way. $\endgroup$ – Craig D Jones Mar 24 '17 at 2:34

    $\begingroup$ Great. I went deeper in my searches and tried once again : and it worked ! I lost the previous example file but i guess the settings I may have missed are those described here : blender.stackexchange.com/questions/19688/… Precisely parameters in the "Slot" menu, when set to Image and the right texture, allow me to directly paint in the 3D View, with a basic brush or a stencil ! Thanks for your help on the different brushes, I'll keep that in mind :) $\endgroup$ – user37096 Apr 2 '17 at 12:45
