Photoshop: 3D Rendering with jagged edges

  • Problem

Hi,

I've been messing around with 3D ind PS CS6 lately, and I've been having a problem with the renders I get.

Most of my renders seems to get a sort of jagged edge. Am I just bad at using 3D, or is this a general problem?

I've attached a photo of one of my renders.


Looking forward to getting a reply, Thanks.

- Michael

I assumed you were referring to non anti-aliased edges (or aliased, in other words) but I see no jaggies in your image.

Which edges in your image are you saying have jaggies?

Yep, the aliased edges. I guess that's a question of a low amount of polygons?

Are you Ray Tracing the image or is this just the OpenGL preview?

Um, I don't know actually.. I just extruded from selected path, messed a bit around with the settings, and hit render.

I'm VERY noobish in the 3D area, so forgive my stupidness.

I talked with a colleague about it, and we came to the conclusion that Ray Traced is the state after the Render, and OpenGL is before the render. Correct?

No problem Michael, we're happy you're trying it out and are here to help. Yes, you are correct. OpenGL is used for interactive movement of the object, when you want a hi-rez render (Refraction, reflection, soft shadows) then you Render it out. For more you can view my videos here: https://www.youtube.com/user/dramenon/...

Well it's an awesome tool, and I want to get better at it, so practice, practice, practice ;) Thanks, I've been looking for a youtube channel with quality Photoshop tutorials, especially 3D.

But my problem wasn't actually only the slight jagged edge's but also, the "emboss" which seems to be very "un"-smooth, from using the Shape Preset called Inflate.

I tried to do some custom work in Cap then, and it pretty much fixed it, but now I seem to have a lot of weird boxes on my rendering. Is this because I haven't let it render through? (The render estimated time, is at about 2,5 hours, and I usually stop it after 5-10 min, to get a look at it.)

I don't think Ray Tracing it longer will help.

I promise I am not trying to further confuse you here :) ... But it looks like the "Normals" are off. Normals are the direction the triangles are pointing and sometimes they can be inverted as well.

If you want to send me the file (email, DropBox, FTP etc) I can have a look at if for you > daniel (at) adobe.com

Hi, I'm sorry for not contacting you sooner, but the project was put on hold. I've shared a folder with you, on dropbox, at the mail you wrote above.

One thing, resolution is important, very important. Start with a document that is at least 2x larger than your final image to create the 3D Extrusion, the larger the document, the better the resolution of the 3D Object when being created, you can then go in and change Image Size down 1/2.

Also, when creating a 3D Extrusion, I believe you can hold down Option before hitting Create (in the 3D panel) to adjust the tolerance of the path as it's being converted to a boundary constraint.

Thanks for the help :) I'll keep it in mind for a future project, involving 3D :)
