Sketch mode question

Tom Krowka — Thu, 11 May 2023 12:30:47 GMT

Have rendered a project with sketch mode. See the attachment. Question is how can I eliminate the swirl effect in the hatching? Have tried various anti-aliasing settings to no avail. Not sure what settings I might adjust.

Thanks.

you'll have to "fake" the patterns' thats causing the swirl effect.
it's just an issue of how close the lines are together.

Kinda like when you look at screen porch and you are looking thru it thru another screen material...they confuse and conflict the eye/brain synaptics into those swirl effects.

just bump up the scale of the vectoral pattern a bit.
see if that helps.

Will give it a try. It seems to be kind of a duplication of effort however. One hatch pattern for elevations, one for 3D presentation.

Thanks. Tom

Well, it's the only offer that comes to mind.
I know that darn "swirl" effect is indeed annoying and can make (or break!) the perspective at times.

Unless someone who has tweaked the graphics on linework can chime in....that's all I can offer.

You could try rendering to a bigger image, then reduce in Photoshop if necessary. The swirls are a by-product of image resolution.

The "moire" effect comes from lines that are to close to each other. As suggested try rendering in higher resolution or adjust the size of the hatch.
