Unique Texture Does Not Maintain the Same Texture

[kmanning]

Hi,
I'm noticing 2 problems in Sketchup. One is that I'm trying to make a unique texture to add to my materials in Sketchup. The first thing I did was draw a square using the Line tool. Here's a screenshot:

But after I right click inside the square and click on Make Unique Texture, this is what I get:

It looks like it has totally changed the size, zoomed in, or something, and is not the same as the original texture. I've just watched a Sketchup video showing how to do this and I'm following exactly the same procedure. It does not do this in the video and creates a new separate texture exactly the same as the original. Why is it doing this? Or is it possible to make a unique texture from a texture in the model? The guy was using Sketchup 2017 Pro in the video, but I'm using Sketchup 2017.

The second problem is that when I select the Default texture in the material, it is not painting the default texture. It's painting another texture that I have within the model, and it's never done that before. Even though I select the Default texture in the material, it does not paint the Sketchup Default texture.

Please post an URL to the video you cited above.

Please attach- or link to- a *.KMZ of your Sketchup project you cited above.

Did you first (re-) align the Sketchup work-space Axes precisely along the bottom of the Face you are working with, so Lines are all co-planar ?

BTW: In Sketchup, it is best, IMHO to not draw Faces with Lines; rather, one 'should' use the Rectangle Tool instead.

When you "select the Default texture in the Material", do you use the Material Tool 'Paint Bucket' cursor while also pressing the < Alt > key ?


PS: One can 3D model more accurately, and position cursors over Vertices / invoke Inferences with greater precision ...by turning off 'Profiles'.

Sketchup Menu > View > Edge Style > check: Edges; un-check all else (especially 'Profiles').

Hi Gary,
Sorry it took me longer to get back to you. It was late when I read your reply and had to catch up on some sleep. Anyway, here's the link to that Sketchup video. I hope I do this right:

The kmz of my Sketchup project is attached below:

But there's something I need to explain here that I've noticed. First of all, the file was created as a component so you'll need to get inside the component to edit it. I have attached both a kmz and a Sketchup file of my project in a zip. In those files, you'll noticed that on the left side of the hangar that I have drawn a square on the pole to make my unique texture. What I've noticed is that when I imported the file as a kmz into Sketchup, that problem did not exist and seems to work okay. It did not go dark or stretch out so to speak. You can try it using the kmz file but it probably will not give you the problem I've talked about above. Another thing I've noticed when I import the file as a kmz is that there are 2 components inside that one file, and that seems strange to me because I did not make 2 components. What I mean is that you'll need to double click, and then double click again before you can edit it. But as I've said, you'll probably be able to make a unique texture using the kmz file without any problem. But when I open the Sketchup file that I've saved, you only double click once and you're able to edit the component. But when I try to make a unique texture using that square on the pole, that is, after right clicking and select Unique Texture, it's all distorted and the texture seems to stretch out, or zoom in. When I apply that unique texture, it's not smooth at all, and it's all distorted and whopped sided.

Did you first (re-) align the Sketchup work-space Axes precisely along the bottom of the Face you are working with, so Lines are all co-planar ?

I don't know if this is what you mean, but when I imported the file as a kmz, the strange thing I've noticed is that the axes was slightly in a different location than what it was in the original saved Sketchup file. Let me explain what I've done, and this may explain the problem. After I've drawn out my hangar, I placed the axes right on the corner of the hangar. Then I found out that I had the dimensions wrong so I've changed the dimensions. This also caused me to changed the location of the axes, and it seems that everything is referenced to the axes I've placed the first time rather than the new location. I even would noticed that in MCX when I was exporting my model. Anyway, this may have played some part in my problem and I didn't do something right.

When you "select the Default texture in the Material", do you use the Material Tool 'Paint Bucket' cursor while also pressing the < Alt > key ?

No. But I think I may know what happened, because the default texture is working fine now. I think what happened is that I had applied a texture to the outside of the component rather than inside, and that made that texture always on top.

Thanks, I'll do that.

Hi Ken:

AFAIK, you are making a unique texture from a selection of an existing larger texture.

The 'Unique Texture' can then be used as a "In-Model" smaller, self-tiling (aka "seamless") texture Material to paint elsewhere.


The attached 3D model has (2) levels of nested Groups (not Components), and all levels of the (2) Groups in the attached 3D model are properly aligned (parallel, even if offset) ...to the 3D world Axes of the Sketchup work-space, so Lines, Edges and Faces should all be co-planar.


I would just explode these Groups so all geometry is at the root level (Layer Zero) of the Sketchup workspace, before performing the tasks described in your OP above.

Whether I click my way into the Groups, or I do the latter 2x 'Explode', I have no anomaly with the source Face or Unique Texture.


Quite likely you had drawn the rectangular Face on the outside of a Grouped Face, then Sampled a Material from that outer level.

When you painted the already-projected 'sampled' Material from a outer level Face onto a target Face, it was 'projected' wrong.

Thus the 'projected' Material UVW mapping of the 'sampled' Material was different than that of the original you intended to use.


IIUC, you have found a way to get this to work properly since you posted the OP above, so let us know if you still have questions.

Hi Ken:

You're probably correct. Now that I think about it, I made the hangar too large the first time and it had already been textured and everything. Then I made it smaller to the correct size and had to resize the textures as well.

The attached 3D model has (2) levels of nested Groups (not Components)
I would just explode these Groups so all geometry is at the root level (Layer Zero) of the Sketchup workspace, before performing the tasks described in your OP above.

I don't understand. When I open these 2 groups, or any of the project files, it says "Edit Components." I've saved these Sketchup files as a Component so I don't know why yours would say Group.. But I think I'm going to explode all 6 of my hangar project Sketchup files so that they're all at the root level, like you said. I think that would be better.

IIUC, you have found a way to get this to work properly since you posted the OP above, so let us know if you still have questions.

Yes. I think I got the problem solved now. It has done that with me many times in the past, and I need to keep this in mind when I have that problem again.

By the way, is there a link on here that explains how to use all those icons? I haven't been able to find it. I've noticed you had in parentheses that I did not quote the image, and I didn't know how to do that. So, if there's a link, I need to go over it.

I do now see in the Sketchup project Default Tray > Components > In Model pick-list that you have saved the 3D model as a Component.

But it does not appear to have special features such as synchronized edits of derived copies that would make it substantially different than a Grouped object.

It is best when working with multi-object "scenes" in a Sketchup project, to keep 3D object database features at a minimum of complexity wherever possible.

Although saving objects as Components is a way to re-use them in other projects via a pick-list, a 3D object in an existing external Sketchup source project can be copied and imported via a "Paste" operation into the current Sketchup target project.

This allows keeping the internal database function of Sketchup projects less complex, as when inter-object synchronized editing is not actually required, Groups are less demanding on Sketchup run time performance than Components.

A component need not be used IMHO, when it is not being used to perform synchronized edits of derived copies; for this use, Groups are more efficient.

One would however, need to remember which Sketchup project contains objects we wish to copy when needed ...without the convenience of a pick-list.

Ken.

I am unaware of a tutorial being available anywhere for the FSDev forum software GUI post editor.

I manually added the comment in the quote from your post that you referred to above, by toggling the BB code edit feature [ ] to / from WYSIYG mode.

Hi Gary,
Now that you mentioned this, I got to agree with you 100 percent that it's best to keep the 3D objects at a minimun of complexity. There was really no need in me making these objects a component.

I've noticed that there's an icon that says "Insert Image," and I didn't know if I was supposed to click that to attach my images. I've always used the "Attach Files" button at the bottom left. Thanks for all your help.
