viewport texturing filtering

[Lo-Fi_Render_Guy]

Please add linear and point texture filters to the types of filters that are available for the camera viewport. I need to hand-paint textures that are at or below a resolution of 512x512. I will be importing them into Unity and will be using their point filtering texture setting. Currently, I am unable to see what they actually look like while I am in the process of painting them in substance without stopping to export the texture, which is not a practical solution. This is making me consider possibly migrating to a different 3d paint program that does have this filter option such as Marmoset, etc., but I would much rather stick with Substance these features were added.

+1 for linear filtering in the shader.

Would like to use SP for pixel art workflows, but currently there is no proper way in SP.

Edit: I meant an option to turn off (bi)linear filtering and use nearest neighbor in the shader instead.

Or alternatively a separate shader for pixel precise painting.
