[Plugin] FredoTools::ThruPaint - v1.3a - 20 Oct 16

Oxer,

Thanks. Did you type the command with Thea installed or uninstalled (because the string is correct)?

Fredo

Oxer

With Thea installed, I probed to type the command before and after to use Thea4SU and the result in the ruby console is the same.

Perhaps Thea uses a materials-observer and that then clashes with how this Fredo tool works ?
Other renderers like Twilight probably have something similar too, without clashing; so it will be fixable, but then that's probably needed on the Thea side...

Many render engines has a tendency to cause instability due to observers. Now, I do think ThruPaint also uses some observers. It's not easy to work out where the conflict lies when most render engines scramble their files (understandably).

fredo6

The issue does not seem to be related to observers but to a corruption in the Plist registry, since Sketchup.read_default returns a corrupted string.
What is not clear is the relation with Thea Render and where this can come from.

I don't know is any other users on Mac, using both Thea and ThruPaint (and Ivy) have met this problem!

I am trying to setup Sketchup on a Mac Mountain Lion computer. When I load Thrupaint the dialog is cramped and tiny. Obviously I can't work with this. What determines this? The dialog for Curviloft is the same.

Has anyone had luck with this and Mountain Lion? It's on a 15" retina display laptop.

Somebody should give you a gold medal dear Fredo6

I really love this plugin, it is probably the one I use most often, just because it makes texturing so much more quick and easy than with the native tool. However, the QuadMesh-Mode does not work when exporting the meshes to other programs, because the textures get distorted. First I had this problem with Walkabout3D and now it happens when I export objects to Unity engine with Playup Tools. Is this due to limitations in Sketchup or could this be fixed somehow? Might this work better with SketchUV? Haven't tried but I think I am going to purchase it, just noticed the price drop.

edit: It worked with SketchUV. Still this plugin is amazing.

The Quadmesh mode deforms the texture, which is not well handled by Sketchup, as it only supports 'perspective' deformation. In some model, this is OK, in others it is not. Very often, the best technique is to have a set of patches with projected texture and take care of their nice junctions. In any case, you are right to use SkethcUV which is a great plugin and is much more powerful for accurate texturing.

Just wanted to add to my previous post, that I have since discovered that ThruPaint and SketchUV really work well together. For example, if I paint a texture in Quadface mode with ThruPaint it will be distorted when I export the model to Unity, as I wrote before. However, when I use SketchUV to triangulate the faces after applying the texture with ThruPaint, the mapping gets preserved and the export works perfectly. So thanks a lot to the creators of both plugins, they complete each other wonderfully.

your interface and icons are ugly, but these tools are EFFING amazing!!!!!! Really cant believe these things are possible in Sketchup (wheres the clapping hands icon) - and very gracious of you to make them free, i will definitly donate!

please fix graphic interface and icons

support， all of the powerful plug-in, Fredo6 the selfless spirit! Admire

I'm not sure I understand how Natural UV mode is supposed to work. No mesh I've tried it with ever got continuous texture mapping like one stock SU painting tool in Alt-mdode is capable of applying. Only the rotation is rarely repeated properly, but the position of the tile in UV space is completely off. Here is a simple example, two bent rectangular columns made with some repeated rotations and pulls. Simple sequence of faces, no triangles, no bidirectional corners.

Stock SU paint bucket tool creates proper continuous texture mapping for each face based on UVs from the border of each previous face (of course, you have to edit the coordinates on the first face at least once to override the automatic projection mapping). ThruPaint produces a seemingly random sequence of tile positions and rotations even if the first face mapping was modified and even though the faces were painted in order, just like with the stock tool.

Some more examples of the behavior I'm trying to get (easily achieved with the stock Paint Bucket tool and Alt key sampling of each face texture mapping through the sequence):

What am I missing to get that essential feature to work? As you surely know, GPUs treat every edge without continuous texture mapping as a set of two edges (i.e. borders of a UV islands), which is why results like those aren't particularly useful if you don't want to render more than twice vertices than necessary. Surely I'm just overlooking some setting or hotkey.

fredo6

Interesting. You seem to understand how UVs work with Sketchup.

Would you have a sample model, with your texture, so that I try and see what is going on.

Thanks

Excuse me how do I download this plugin?

Thank you so much!

Sure, here is a model with that texture, two sample meshes and two examples of stock texture mapping. Switch between the scenes to navigate it.

Just a moment...

I am not sure of what you try to achieve.

You cannot paint the shape in one go, because ThruPaint will try to go around the shape while going up (The first goal was to paint smooth meshes).

So you need to paint each side separately, as illustrated in the video.

Yeah, I'm interested precisely in painting each side separately, obviously. ThruPaint is not producing the mapping similar to depicted on your gif for me, though. Maybe I don't understand something about controls? I'm sequentially clicking on the faces. Should I hold some additional button for Natural UV to come into effect?

You have to click and drag without releasing the mouse button.
