In the bottom of the image four spheres are shown which are shaded with the matcap in the top portion of the image. The matcap is a “perfect” circle on a black background. As you can see the background bleeds into the image at the borders. This is kind of expected an can easily counteracted by making the sphere slightly larger. However the matcap also seems to wrap around and for example take colors from the left side of the image on the right side on the sphere. This cannot be fixed by making the sphere larger. Also it is common for matcaps to be light on one side and dark on the other. This causes artifacts when viewing something not centered on screen while a perspective camera is used.
Both these problems could be fixed by shrinking the radius of the circle the matcap actually uses by one pixel.
I have partially blurred my first Matcaps, because when I tried modeling with them they overloaded me. Initially I put lines and boxes to show the relief better, while you check a model all the details are appreciated, but while sculpting they confuse.
I leave a capture of the two versions, apparently they vary little, but when you model you notice a lot.
I was thinking this exact thing. I don’t know if preset system development will extend to matcaps, but it would be pretty useful to be able to change various aspects of default matcaps and save them as needed.
Hi @pablovazquez,
This mocap can be used to test models for surface irregularities while modeling.
It doesn’t look nice with the waspbot so I attached an image with Suzanne for a clearer example.
It’s been discussed above by @So3Datel too.
Below is the link to the matcap .exr and attached images of matcap and sample.
Here are two matcaps that I hope you find useful. The reflection check matcap is set up as well as possible with near perfect AA and 32 light and dark bands (hopefully just the right amount). I have tested both quite a bit to ensure they are high quality.
Hope you like them!
Hope the jpg matcap and the possibility to add them will be removed forever since 2.8 viewport is color managed.
Otherwise it’s confusing for peeps not aware of color space stuff, plus it’s an aberation to color managed an already baked 8bit jpg (even linear jpg).
We definitely need something like this. Maybe a grid, vertical variation, or the ability rotate matcaps (maybe just in 90 degree increments) would be useful too?
An attempt at creating a hybrid of both horizontal and vertical reflection checking.
I used low frequency horizontal reflections and high frequency vertical reflections. Also tested to ensure quality. The high frequencies are a little blurry at sharp viewing angles. However, overall it works very well.
