Wrap-R for SketchUp

TIG · 25 Mar 2019, 23:44

In SketchUp there are 3 modes for 'marking'.

The starting default is to highlight and pick an individual 'Seam' edge.

Pressing Shift changes to 'Loop', where a connected loop of edges is highlighted en mass, based on angular divergence rules which determine the most likely loop of edges connected to that hovered-edge.

Pressing Ctrl changes to 'Path', where you pick a number of connected edges, one after the other to be marked by confirming at the end.

You can circle through these 3 modes using those modifier-key presses.

Pressing TAB toggles between marking and deleting Seams in any of the modes***.

The Status Bar at the bottom shows the current mode, and what key presses will change what...

In each mode the hovered-over edge's color and then its subsequently marked color changes, as does the cursor itself.

Seam == Light green on-hover
=> green marked edge, on click to confirm

Loop == Purple loop on-hover
=> green marked all loop's edges, on click to confirm

Path == Orange edge on-hover, and when picked all path's orange edges also have a temporary 'selected' [blue?] edge inside them
=> green marked all path's edges, when you press Enter/double-click to confirm

***Delete = Red on-hover - in Seam mode it deletes single edges, in other modes it can highlight and delete any found and highlighted loops, but only where appropriate...
red => unmarked edges on a confirming click.

Obviously if you press Shift for any other purposes while using the toolset then that is taken as a modifier press by the toolset, possibly changing from the current mode to 'Loop'.
So if you want to safely 'Pan' during your marking, I suggest that you use a shortcut - e.g. I have one set up for Camera/Pan so that I press H to activate the 'Pan' tool.
You can of course set up your own shortcut key-press alternative...
Then Pan run in this way will NOT affect the current toolset's mode setting.

But if you don't want to use a shortcut, then you'll need to commit the Ctrl generated Path marked thus far, by pressing Enter or double-clicking, then do the Pan with Shift+middle-button, and afterwards you need to press Ctrl again to recommence the toolset's Path marking mode from where you left off - the Path marked thus far is now shown in green, and any new addition to that Path are indicated as usual in orange/blue etc, until confirmed.

Sorry I am not making myself clear

I am in Su not Wrap-r and I am marking the seams.

Yeah, I thought it was about the standalone Wrap-R Sorry
I hope TIG's comprehensive guide above helps. Thanks to him for the detailed explanation.

Thank you very much for the reply - yes it answers the question

Quick Question is Wrap-r compatible with sketchup 2019?

TIG · 13 Apr 2019, 14:06

Gábor posted 'Yes' - a month ago in this very thread: https://sketchucation.com/forums/viewtopic.php?p=646896#p646896

Working hard to make docs for next week. But I cover most things in those videos above.

Two years later still no written docs, no clear guidance manual, shortcuts key list etc.

Wrap-r plugin error SU_ERROR_SERIALIZATION. When I click “Send to Wrap-R” I get such errors.

Hi there, I purchased Wrap r about four days ago and still don't have my Activation key.
i sent you a email through your website, I have checked everything in my email account and the only thing I have is the purchase confirm reciept, Please can you forward this on to me please.
Thanks

What about the possibility of setting a minimum margin between islands.
Sometimes the resultant ones are too close one to another. If that happens, I usually have to face some color contamination when I'm painting the model

jonorman · 23 Sept 2019, 05:49

Hi, I tried to contact the WrapR support 2 times, but there is no reply.. Did i miss somthing or are the Site/company down ???

iichiversii · 18 Oct 2019, 19:54

Guys, I am having an issue with using the relax tool, to be honest I don't know how to use it, some areas of my model are in the red and blue when I open the view stretch texture, I just want to relax that area of the model, so I select the area where I need to stretch and click the relax tool, noting happens, is there any tutorial on how to use it, I cant find anything, there even is no documentation available, any help would be much appreciated

optimaforever · 17 Sept 2020, 20:39

I never understood how relax worked in WrapR... It's way too slow too.
Is WrapR still under development? There are so many things I'd like to ask...

Too bad this great plugin doesn't get the attention and support it deserves from community..
Maybe we as active users should promote this a bit more..

optimaforever · 30 Nov 2020, 17:23

Indeed.
I regret that SubD/QFT quads don't export as quads correctly, otherwise Blender has very good unwrap tools. But as it is now, Sketchuppers are forced to work with SketchUV or WrapR for their UV tweaking.
And unfortunately WrapR is damn slow/not featured enough compared to Max or Blender counterparts.
The workable polycount is very low. It's only usable for small models with low complexity. The Undo is not always working/too slow. In Substance Designer, I often tend to rely more on the beta Unwrapper on an straight (no-unwrapped) fbx exported from SU because of that...

I think this plugin is underrated because it's too expensive for its features (and because the casual Sketchupper don't care abut Unwrapping) and therefore too small userbase to really push it forward.

I dream that Thomthom takes the code and embeds it in his QuadFaceTools v2, working hands in hands with VertexTools 2 and SubD 2... For me, it would make sense as WrapR can't work without quads anyway, and so is dependent on QFT and SubD...

Intersting points.
Honestly I don't have much problems with the polycount, mainly because in the last few years I did most of my modeling for interactive/VR/AR/game engine use, so I tend to keep my vertex count quite low regardless..

Another trick to improve usabilty is to unwrap on a low poly version and then subdivide and send it to Substance, 3dsMax or whatever software is needed.
Quadface tools exporter works fine for me with Substance Painter.
In 3dsMax needs some workaround, but still usable.
Wrapr itself can export a good quad OBJ which work with less workarounds in Max, the problem is that with Wrapr you are forced to work on a single material for each mesh.

I also found some neat tricks involving the excelent Fredo Thrupaint to enance and speed up the unwrapping in Wrapr a lot.
Maybe I'll do some video about this tecnique in the near future, because it looks like noybody else had figured out those tricks..

Too bad Rich "disappeared" from the community, I'd like to share with him some knowledge on this matter and see if some logics can be included in Wrap-r itself.
Here is a video about my process creating assets with Sketchup for VR applications, sometimes I also include other softwares, mainly 3dsMax and Topogun, but in this specific example I do 100% of the modeling in Sketchup (plus QFT, VT2, SUb-D, Split tools, JPP, Thrupaint and of course Wrapr).

optimaforever · 2 Dec 2020, 11:01

Thanks for the interesting video showcasing your workflow.

I have a pretty similar one (offset loop being a well hidden QFT feature only accessible by the shortcut or the menu ). I agree that Bridge loop tends to make mistake by offsetting some corresponding vertices (but again no biggie, Curviloft can help indeed). There is place for improvements here

But I'm amazed by your mastery of Wrap-R... With my meshes I can barely move vertices and it bugsplats (old SU acquaintance) often so I need to save all the time. The way you align the rims faces of the butterfly chair seems brute force... but it makes sense as you will later apply a parallel wood pattern in SBSPainter.

BTW Do you have a particular technique to quadify an exported SU quad mesh in 3dsmax or Blender? Mines always import as tris and unwelded. I'm not an expert of Max and can't find any tuto on the web for this kind of case... When you model in Max, the mesh vertices are weld by default so Maxers don't understand my issue. I tried QFT's export as OBJ and it indeed LOOKS like a quad...

but when I apply a turbosmooth (or a meshsmooth), it reveals that it's a tri...

Because of this, I can't use the Unwrap tools because it can't detect seams on TRI meshes...

So according to you, one can Wrap-R a mesh in low poly, reload it in SU, then subD-it and it will keep the unwrapped status? I never tried this.

This one for instane was a nightmare to WrapR...

Outastanding job on that car, I hope I'll be able to get near as goood results on my Ferrari F2004 model, whenever I eventually complete that WIP

Yes, that unwrapping tecnique works best for parallel patterns like that one or other similar things like stitching at borders, bricks and this kinda stuff.
Honestly since I relased that video, I found a neat trick to perform that specific operation waaaaay faster and better.

Yes it does something strange in the latest build of the quadface tools exporter. Older versions used to work better I hope that in the near future Thomas can take a look at this problem.
Meanwile I've found a tricky and quite fast workaround in 3dsMax to fix that. (the actual quad clean geometry is still there you only need some brutal cleanup to get rid of the unwelded floating triangles).
The other method to export a proper quad model to Max is to produce an obj with wrapr itself.
This also can lead to some minor glitch in form of apparently missing geometry, but again, is quite easy to fix that.

Yes, that's perfectly possible with some minor caveat.

I'll try to do a short video as soon as possible demonstrating all of this, maybe could be useful both for existing users and for the developers to further improve the process. Stay tuned and forgive my bad english in advance..

optimaforever · 2 Dec 2020, 12:37

Thanks!

Your Unity model and skills are impressive as well. I'm more a Lumion/Twinmotion guy than Unreal but there was a time when I modeled in Worldcraft (Half-Life modding tool) and had to scrutinize everything under the hood. Now, there are too many tools I need to master (from Sketchup to Allegorithmic tools, Fusion360, Blender, Zbrush, Resolve, After Effects, PS, Vray, Thea, Max, Wrap-R, Transmutr, Quixel Bridge, Megascan, etc. etc. once upon a time I was happy with just Sketchup and PS) and can't allow a lot of spare time on details (and god knows Unity and Unreal need a lot of things to be learnt)...

Your bad english is way more understandale than mine
So yes, I'm curious to see that!

BTW please place the text in a better position as it will be easier to read (in the video), as the bottom right isn't the best place as our eyes must continuously switch between the action (generally at the center of the frame) and the text.

panixia · 15 Dec 2020, 12:47

Work in progress..
Sketchup (and of course QFT, VT2, SUbD, JointPushPull, Split Tools, Wrapr) + SculptGL + SUbstance Painter.
I think I'll discuss this as an example for the video.. Stay tuned
