[Plugin] UV Toolkit

thomthom

I'm still lost, your plugin can combine the numerous textures

No - the user makes a texture.
In the case of the tree, combine some textures of leaves into one texture. Apply these variations to a set of faces. Copy their UV to the UV clipboard. Select the remaining untextured leaves and paste the UVs.

That makes it very easy to manage your materials. For instance, you could then you edit the one texture to a different set of variations and all the leaves will be updated on one operation.

As for gaieus' example he could make a texture with a set of variations of bricks.

I'll be making a video with a quick example when v2.2 is done.

What a great addition mate! I can think of a great way this will assist workflow in my case - as you mentioned 'sprite technique' I've never heard it termed that! But already use this for mapping all my furniture, fittings, carpet, tiles, wall and ceiling colours, light fittings etc for internals on exterior renders - all to the one map so that I clear about 20 materials out of my material browser and have just one material in maxwell.

This plugin will help to spread these over randomly inserted objects! WOW!

You are a god!

Thanks Thom for this nice plugin!

Just leave that for Rich (once he finally understands the plugin).

I'm in constant awe of you and all the other generous Ruby contributors. Your work has taken SketchUp to another level. Many Thanks.

How about i post that video of you in BaseCamp surrounded by an enthralled audience!

whut video?

I'd like to see that, I saw some of Mateo's facebook images and would love to see MORE!!!!

Mate I played around with the plugin for a tree trunk in combination with fredoscale and I ended up with a mass of assigned materials (all the same) when exported to maxwell. I noted this before with Whaat's UV tools (cant remember the name of the plugin).

Funny though it was only for several faces - I'll have to test some more and see what went on there!

Mate dragged over from Whaat's UV tools thread!

@unknownuser said:

ThomThom I'm not entirely sure, but I'm guessing the Maxwell exporter exported out a texture for each face with a distorted texture.

Mate I think it well could be that as only a few faces effected it would be likely these subdivided during editing.

BTW starting a new thread for you to check out regarding a workaround for locating HDRI worked out how to do it in SU and you might be able to automate it a little.

Richard,

Indeed UV Toolkit 2 only works properly if the number/shape of the initial faces is the same as those of the end result.

If during a distortion operation faces get subdivided further, it fails. You can pre-triangulate your faces first if needed however.

I found that after I manipulated my mesh, it rendered properly in Twilight and Thea (neither of which "likes" distorted textures AFAIK) so I thought the plugin fixes texture distortion.

You mean when using UV Memory?
That doesn't fix anything - in fact, it doesn't reapply distorted textures to triangles, they end up as skewed textures. Though, if you have a dense triangulated mesh you probably don't see the artefacts.

Well, I used triangulated faces here and it re-applied the texture perfectly:

(skp also added in that post)

And it also renders the twisted/bent "column" correctly (all faces are triangulated)

Triangulation is probably a good solution to deal with render engines. Maybe I should add an option to triangulate (soft/smooth the new faces) to the UV memory tool...

Irvine,

Please, go back to the first post (where you downloaded the plugin) and follow the link to the TT_Lib library. You will need to install that, too.

Not a bad idea (although there are triangulating plugins available). However I had no issues with it without the triangulation (where it was not needed) otherwise (testing in Twilight and Thea only)

I would be more interested in that sneak preview of UV Toolkit 3 (with the copy > paste function from other geometry). I have now a project where there are vaults and domes of the same kind but completely different sizes/distortions...

v2.2 - I'm wrapping it up.

Gaieus

Well, I answered your PM (that it is not that bloody urgent yet) but if it is not that much of a work...

thomthom

Ah - you need to transfer UVs between whole surfaces, not use individual faces... ?

Gaieus

Yes. I guess(ed) the plugin would work that way, too.

Currently I (sort of) "copy" (or "memorize") the UV's on a mesh and then restore them. In my thoughts, it would work the same way with the improved UV Tools just it could (also) transfer these co-ordinates from one mesh to the other.

Sometimes you can quite easily apply a material to a certain shape but if you modify it further, it is not easy. Then here is a quick (and rather dirty) example. I will have all different shapes (tapered and distorted) vaults that are derived from the same, quite regular shape. If I texture each separately, it will take forever.

But even a better example: this way you could easily apply a texture to a flat (yet subdivided) (sur-)face then copy the UV's and apply it to a completely modified mesh.
