Title: Wrapped Textures - Checkerplate
Post by: Non_Liquet on July 26, 2011, 06:34:59 PM
I'm trying to apply a wrapped texture to an object to achieve a checkerplate appearance in v17. As there doesn't appear to be a checkerplate pattern available in the library (was there something in previous versions?), I'm applying a photo I've taken. The problem is that the wrapped image is clearly tiled. I'm looking for some direction in how to achieve a seamless checkerplate finish.

OK. I've found something under materials editor. I must be tired - I was sure I'd been through all that :) It's enough to get me through today, but I would still like to be able to wrap my own image seemlessly. If anyone can help I'd love to hear from you.

As long as the image itself is capable of seamless wrapping, most Wrapping modes will do it seamlessly. Post the image and the TCad drawing, and somebody will surely help.

Thanks for the feedback. Here's a small TCad file with a part, and an image of checkerplate. I've tried to get a section of checkerplate which is evenly coloured, but I'm still getting a tiling effect across the part. I'm not very good on lighting, & maybe that's part of the problem. Anyway, any advice will be appreciated.

Looks like I didn't attach the image file correctly previously. Let's try again.

It's past my bedtime in this part of the world. Pretty sure I can fix your problem, but it'll have to wait until tomorrow ;-)

There's an excellent chance that somebody else will fix it in the meantime.

Try the attached "Checker Plate_via TCad.jpg" in lieu of your photo. Use it in "Wrapped height map" Texture. I specified "ST layout" Wrapping, with Rotation = 45 deg.

Thanks cery much Henry. I'm very happy with the result. I played with S & T scales a bit (set both to 100) before I could see much detail. Don't know if I should have, but it all looks great.

Yup, you should have. That's what the scales are for. Glad it works for you.

Just curious Henry, does your texture have a negative (indent) around each tread?

If you're wondering about the narrow darkish region bordering each tread, Julian, I was concerned that it might create the impression of an indent when rendered. Couldn't easily get rid of that region, so I gave the image a try as-is, and it seems to render just fine.

Yip, that's what I meant, and you're right - the render does look good. Here's my version, the texture was created with MS Word.

That's really excellent, Julian. I had no idea Word was capable of such things. My own texture image was created by making a 3D model of the checker plate in TCad, then massaging a screenshot in Paint Shop Pro.
