[Plugin] SketchUV - now free

... You should be able to get it very accurate ...

This, unfortunately, is not enough. For example, if I impose a texture on the wall of the glaze. I need to be able to apply precise dimension, for example, has a plate size 597x597mm and 2mm on the fugue.

Currently, I was faced with the problem that I have a lot more texture than the object (very fine texture of wood) as in this case, to deal with texture mapping on a scale of 1:1.

The Quad Face Tool plugin is the function of the "Use material size". Maybe it is also possible to introduce such a feature SketchUV.

I do not want to be the smartest but you may want to change the approach to the dimensions of texture. Maybe instead of using the '* 5' or '/ 5', convert it to a percentage system. 100% texture dimension 1:1, 80% reduced texture size, 150% increase texture size. All simple and clear, and always under control.

I'm curious what others Total Members this plugin think about it.

Or maybe there is another opportunity to have full control on the dimensions of texture?

Hi,

I've been using the plugin for some time now and all works great and love it!

But on my latest project I encoutered a problem with SketchUV and transferring the mapped texture/UV's to Thea Render.

Let me try to explain

When exporting a model from SU to TR via the TR-plugin, I get a model-entry with every material I applied in SU. This entry has the UV's included.

When I map an object in SU with the Planar or Box tools, the mapped texture is correctly transferred to TR with the correct UV's.
From here on out I can properly apply any TR material I wish.

But, when I have mapped an object with the Cylindrical or Tube tool it all goes wrong:
For every face of the object, an texture is imported, named as the main texture (i.e. 'SketchUV') and folowed by a number (i.e. 'SketchUV-21').
This gives an enormous amount of modelentries in TR and keeps me from properly appying a material in TR.

Here a simple example setup:
Basic object with the different SketchUV tools applied

The way of exporting the object to TR

Here the object in TR mapped with Box tool
Notice that in the tree, under 'Models', there is just one entry of the texture (=correct)

Here the object in TR mapped with Cylindrical tool
Notice that in the tree, under 'Models', there are 23 entries that came with this object.

Here the object in TR mapped with Tube tool
Notice that in the tree, under 'Model', there are 288 entries that came with this object

Is there something that I'm doing wrong or is this just not right?

Hope you understand the problem and can help me on this one!

Did you try triangulating before exporting?

What version of the Thea plugin are you using?

sh00ks · 16 Dec 2012, 09:29

Rich,

Thx for the quick reply!

In the examples there is no triangulation, 'cause I thought it didn't matter in this case if it was triangulated or not and tested it before.

I was wrong

Traingulation does the trick!
Before I only triangulated when mapping was doing something weird, but from now on I'll always triangulate

Thx for the (oh so simple and obvious) solution!!

When I was testing your solution I encoutered another thing I don't understand and I hope you can enlighten me on this one:

When tube mapping, I encouter an error (see attachement) when I first triangulate the tube and then apply tube mapping.
When I start off with tube mapping and afterward triangulate the tube, it works.

Is this (first map, then triangulate) the preffered way or is there something I need to change to first triangulate and then map without the error?

Rich O Brien · 16 Dec 2012, 09:35

Tube Mapping only works on quad faces. So if you triangulate it's not a quad.

sh00ks · 16 Dec 2012, 09:37

Again, thx!

First of all - I love the plugin. Thank you so much for your work. This is my major tool for uv mapping.

When I uv map different groups or components of different sizes I get different sized sketchuv texture. What I usually do to normalize them (make their texture sizes equal, see the screenshot) I just use '*' or '/' operations but this is extremely time consuming for hundreds of different groups and in most situations this gives me only approximate results. So my question and big wish is - is it possible to add extra feature to auto normalize sizes of the same sketchuv texture?

Kind regards,

Sebastian

HI

Looks like a great plugin. I am considering buying the plugin.
I am the user of Sketchup and Octane render, have any one tested if the UV mapping created with sketchuv are correctly exported with the octane render exporter (made by TIG).
I mean both normal faces and triangulated faces.
???

Hi Sebastian,
What you are suggesting should be possible. I will consider it in a future update. Thanks!

It should work fine with Octane render. If you are getting unexpected results, try triangulating your faces using the tool in SketchUV. The tutorials on the Smustard website demonstrate the workflow.

Hi

Thanks for the confirmation.
One more thing i need to check before I buy is... Will this UV tool be able to handle wood veneers / materials well??

I have some curved parts with a big rounding on the edges where I want to apply a wood material.

I have attached a link to the skp and wood texture file, can you pleas apply it on the part so it goes nicely around the curved and rounded edge.???
If it work it will save me hundreds of hours and I will for sure buy the plug-in.

Pleas tell me if the link do not work.

Dale,

Such update would be awesome and extremely useful for my current work.

Best wishes,

Claus,

All uvs are properly exported using TIG's exporter. This is the only exporter I am using for Octane render. In your example I used tube mapping, which is extremely useful on round edges.

Kind regards,

smicha

HI

Thanks for the demonstration, it seams that there is a texture lineup problem vertically in the middle of the component but i guess it is just a matter of adjustment.
Also it seams that the texture on the flat surfaces do not continue on the round surfaces, but again i guess it is a issue that can be solved.

I will most-likely buy the plugin and test it out, hope it is easy to use and can make some of my texture mapping easier.

HI

Have now bought the plugin and tried it.

What happen is that I use planar mapping and it wrap the sketchUV texture around the component. I save uv's and then apply the texture that i want to use on this surfaces, then i load the uv's. what happen is that it re-scale my texture in a non-uniform way. My texture is a 10000x3300 pix png file and it looks terrible.

How to keep a uniformed scale of you end texture while using sketchUV???
Something i miss here or???
Or it can only be used with squared sizes-ed texture files??

Claus S

Can you post a screenshot?

Whaat · 18 Mar 2013, 18:19

Yeah, a screenshot might help. Can you fix the scaling by adjusting the length and width values in the SketchUp material editor window?

clausgs · 18 Mar 2013, 23:00

HI

On the attached pic you can see o the left a 10000x3300 mm plane where i have applied a texture (10000x3300 pix png file).
Now i make a simple curved surface and apply a planar map with sketchuv, you can see that the sketchuv texture are re sized to fit the whole curved surface. I save the uv's and apply the wood texture and load Uv's, what happen is that the 10000x3300 pix texture get re-sized to fit the whole curved surface.
now i will need to re-scale the wood texture with sketchuv manualy what never will be perfect.
If i change the dimensions in the texture / material editor it will re-scale all textures in the whole model.
Any solution to that issue???

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....
