View Full Version : Toggle for Canvas Lighting Gradient

Hello, a quick suggestion here.

Sometimes it would be great to keep the canvas grain and 3D paint effects in the engine, but remove the gradient overlay that slightly darkens on canvas (especially down to the corner).

There is an opacity toggle, but it doesn't seem to effect the light.

If this process could be separated into its own toggle that would be awesome.


----------------

Reasons: it darkens ares of the picture effecting the composition. It requires compensation by painting lighter values. It impairs the ability to color pick previous paint colors accurately (as it picks from the multiplied effect and not the paint underneath).

AH, unfortunately not. The canvas textures are basically shadows cast by the lighting. Without the lighting effect, there is no visible texture, and it's not currently possible to hide some lighting but not other bits.

(Oh, you can set the colour sampler to ignore lighting in the tool settings).

I have a suggestion. Create a layer at the top of the layer stack. Edit the layer texture to use a negative roughness value. F5 that canvas light off and then with a large soft wax crayon set to a deep tone, cover the layer as evenly as possible trying for about 50% "Bite" into the texture. Switch your blend mode to overlay.

This should give indication of the canvas texture without the lighting. Dial in the layer opacity to taste.

Thank you both for the replies.

I was hoping that the general gradient overlay, and the lighting that gave the canvas texture were separate procedures. Color picker tip is helpful!


Fashmir: that is an interesting idea to try as well. In the meantime I have also done this which helped isolate the gradient a bit:

1. New layer
2. Set to overlay (to lighten)
3. Airbrush, with a large size, along the bottom to make a white gradient favoring the shaded lower side (could use gradient tool with transparency also)
4. Adjust opacity.

This can slightly reverse the gradient without washing out the texture.
