[Plugin] SketchUV - now free

clausgs

Claus,

The solution for your problem is simple. Please attach the bent shape in skp file and I will write exactly what to do.

Hi

Thanks for offering a solution...
The attached skp is just a simple sample,,, my components are many and very different in shape. So what I am looking for is a general solution / workflow to keep the aspect-ratio of the texture....

Claus,

Rotate the texture by 90deg. - simply select faces with the texture, run sketchuv, type 90
Some calculations: 3300/1250 = 2.64; 10000/3670 = 2.72.
Again, select faces with the texture, run sketchuv, type /2.64v, then /2.72u (u and v are changed/shifted due to the prior rotation in step 1.)

PS. Your problem is strictly connected with my question about normalizing size of textures. It would be great to select one texture and normalize its size on different objects. I hope to see the update of the plugin soon.

Kind regards,

smicha

HI Smicha
It works, but it is a very time consuming process, and to keep track of the U V direction is not easy.
Thanks for your instructions.

Dale
There for sure is space for improvement or should I say functionality of this plugin.
You see to keep the aspect of a texture is very important when you use wood textures, but even fabric and other textures that are more of an even pattern need to keep the aspect.

Dale, what can be done on this issue???

I bought the plugin and it do what it say, but I can really not use it for many of my projects.

I completely agree with Claus. When we apply a texture on any surface using any method its dimensions should match (within small error) dimensions of a texture that is entered in SU.

I agree that proper scaling should be done by default in SketchUV. Hopefully, in the future I can implement this. You might want to try ThruPaint by Fredo. I think it might do what you want.

Hi
Yes tried the truepaint and it do a very good job in many situations. and most important it keep the aspect. and that is what sketchuv is missing 100%... It is not really workable in the way it handle aspect today.

Another issue I have found is that the triangulation in my models are not working 100%, some times it create holes in the surface. Pleas have a look at the attached pic.
What am i doing wrong? or is it the model? or is it the plugin?

smicha

Claus,

Measure the sides of the triangles - if they are less than 1mm this is the reason why holes appear.

A solution can be: before triangulation scale your model, eg. 10 times, then triangulate, then scale your model down 10 times.

HI
Thanks for the idea, i tried it and it works, great tip for me.

could this not be incorporated into the plugin also, first investigate all lines for the length, if any is too small, then scale the model as needed and then do the triangulation and then re-scale the model.

There is not a plugin which exports all mapped textures in a model to one texture file.

Ultimate Unwrap 3D can do this with imported .skp files but I haven't tried it yet. It's also about $50 so more expensive than this plugin.

Is this feature similar to a Texture generator atlas

Thanks. I will most def buy this once I can get the hang of Roadkill. I was wondering, any future plans on having a add on that will pack the shells on a 2D surface so that the UV map can be exported to be painted in Gimp etc ?

Sorry, nothing like that planned right now. Thanks for the suggestion.

I tried using SketchUV to map the trunk of a tree made with the plugin 3dArcStudioTree. I hoped cylindrical mapping would work. Do I have to go the 'roadkill' way or are there any other options to try?

Greetings, Max

cotty

It should work. Can you share that model so that we can search for the problem?

smicha

Tube cannot be triangulated before uv-mapping. Otherwise remove triangulation.
I suggest trying thrupaint for such triangulated tubes - it works great.

Here you go...

3darcStudioTree_SketchUv.skp

smicha

clean your model (bottom especially)
use thrupaint

the file is attached

Do you plan to add the function to normalize different sizes of textures - I asked about it in previous posts?

Yes, but I can't give you any accurate estimate of when that would be. It could be anywhere from two months to several years away.

I just bought the plugin, and am very happy with it. I read the user manual as well, and have a question using the path select tool. Is it possible to weld a piece back after it has been cut, like in most UV mapping software. I sometimes accidentally double click on the wrong line, and I hate to have to start the whole line cut again on a large model.

I tried holding the Alt, Shift, and Ctrl Keys separately hoping they would activate the opposite of cut, but they did not.

Thanks
Jason
