So I’ve trying to use snapshot 3D and I’m curious has anyone found a way to increase the resolution so that the corners to soften so much. I am trying to find a way to have the snapshot be more accurate to the actual alpha. I know there is a detect corners feature and the smoothness sliders, but they don’t really help increase the accuracy. I have an alpha with square corners and a round cut out and well when i use detect corners it makes the round cut out faceted, as well if I mess with the smoothing sliders it will warp lines. A perfect triangle will shift slightly and no longer be a perfect triangle.
So long story short is there a way I can increase the resolution of an alpha to get a more accurate snapshot?
Use the spotlight scale function to increase the size of the alpha prior to snap-shotting. This will produce a mesh with higher resolution.
You seem to already be aware of the Preferences> Spotlight > Retain Corners, Smoothing, and detect corners settings.
Be sure the alpha in question is high enough resolution. A low res, blurry or pixelated image will produce softer results.
As with many things in Spotlight, snapshot 3d is redundant with other functionality in Zbrush. If you can’t get the control you want, investigate the Alpha> Make 3d or shadowbox features instead. They may offer more intuitive control.

Note that the optimum resolution for an alpha for use with SnapShot3D is 512 px x 512 px. Anything larger will be reduced by half until under those dimensions - so an alpha that is 600 px square will be reduced to 300 px square.

Ah good to know, Marcus, Thanks! Was just speaking about general alpha-stamping principle, but that doesn’t seem to apply here.
Thanks,
I’ll give it a shot. I like the idea of it creating cleaner topology, but if it distorts the shape to much it defeats the purpose. I may try shadow box and then use the new zremesher to try and get the results I’m looking for.
Did you scale the Alpha up first prior to using snapshot 3d? It drastically increases the mesh resolution and accuracy.
And of the two alternatives I listed, I would definitely try the Alpha> Make3d first over shadowbox. It is very accurate if created at high enough resolution.
