There are many tutorials on how to use multiple textures in modeling detail onto the mesh but it seems impossible to find how to paint or stencil paint more than one texture onto a single object.
Is there a way in Blender to import or open multiple image textures and use them one after another on various parts of the same model like you can in other texturing apps such as Sculptris?
Thank you for your time.
The way I do this is pretty useful to me, so I will share this method here:
First, select the images you want to use and make copies in a new folder, renaming them with whatever tool or program you want to follow a sequence like 'image.001, image.002, etc' so that the same image name is shared and they follow a sequential number.
Load them as a new brush texture or brush mask depending on what you want to use them as.
Add a timeline editor to your workspace if not present, and set the end frame number to match the number of images in your image sequence.
Use the playhead controls or the left/right arrow keys to switch images as you paint.
Another neat trick is that you can press the Play button and paint, your dabs will change texture corresponding to where the play head is on the timeline. This can be used for many effects like randomly mixing wear images or changing scratch marks, or even just imitating Alchemy for idea generation.
First, create a material for the object with whatever base texture you want (or just a base color).
Then, in the texture panel, create a new image texture for each texture you want to paint with.
Finally, in Texture Paint mode, under the brush settings (found in the Properties window under the Active Tools tab), Under Brush Settings -> Texture, select the texture you just created and start painting with it.
Hope that helps.
