Texture Mapping Curtains

jo-ke

I'm textureing my curtains with quadface tools

the result is very nice and it's fast and easy to use.

Hi there, I've tried to upload the skp. file (which only contains a pair of curtains) and it says that I've exceeded the maximum allowance???!!!

I've also downloaded Quadface Tools but can't access it within SketchUp - I've obviously done something wrong...any ideas?!

Can you post a picture of the mesh of your curtains (with hidden geometrie)
Or upload the skp somewhere else and post the link here.

Ok, here's a JPEG of the two different types of curtain that I've been trying to texture map recently and they look good when viewing them at front elevation but from the side the patterns are distorted.

Did you look a my tut on umwrapping in Blender?

There's absolutely noway that'll map in SU unless you spend time converting it to QuadFace compliant

are those polys I see? I would say those could be a lot lighter... might want to hit ThomThom's cleanup tools or artisan's poly reducer.

I've been playing around with Thrupaint and it's providing an excellent UV projection of the required texture BUT it isn't projecting it at the right rotation. These stripes should be vertical - when I try to rotate the texture using Thrupaint it distorts the texture. The JPEG material is vertical so I'm not sure why this is happening?

Neets,

With the projection mode of ThruPaint, you have 2 parameters to choose

the plane of projection (via the floating palette). Instead of choosing the default, which "picked face", I guess you should select the vertical plane of the curtain.
the initial orientation, which is indicated by the samm red and green UV axes when you mouse over the faces.

But the fact that it is distorted when trying to align the texture 'vertically' has nothing with Thrupaint or the native SU paint bucket tool.

This is simply the normal behavior of any planar texture projection. Since the curtain is folded you will always have some parts which are almost perpendicular to the projection plane, and thus heavily distorted.

Only a Mesh mapping can make it. So the best is probably to use SketchUV and map it in an external software that can cope with this type of convoluted surface.

Try clicking my signature you never know what sh!t turns up in there

Rich, great tutorial video. For some strange reason it's importing into Blender at a 45 degree angle. Not changing any of the texture positions in SU nor the position of the model.

Rich O Brien

Are you using SketchUV Gus?

Did you explode the model to remove it default axix position?

Did you remove the mats applied to the group and not the geometry?

Darn,

I had posted a reply and for some strange reason it hasn't appeared. I said something like; 'Fredo!!! The infamous Fredo!!! Thanks for your reply! I shall act on your instruction tomorrow but I'm currently onto my 3rd glass of wine and singing into a mirror using my hairbrush - cos we all gotta take a step back (even from my beloved SketchUp) for a wee breather'

Thanks
Anita

Rich, how on earth do you know all of this stuff??!! Huh?!

Rich O Brien

I don't I just pretend

neets

Yea, right...!! If I can work out how to get those stripes to appear as good vertically using Thrupaint I shall treat myself to ANOTHER glass of wine!!

Opened the skp. Removed the material from the group. One iteration of Artisan smoothing. Applied material. Exported UV with SketchUV within the group not moving or having rotated anything. Imported obj into Blender. Scaled it down. Right click and smooth. Tabbed into edit mode and click U and then UV unwrap. Then I switch over to texture mode and it's at 45 degrees. Tried it again with a fresh download of the skp in case I moved anything earlier.

@Gus

In the UV editor hover over the unwrapped mesh and press L to select it

R to rotate it

If you can give me a link to that cloth as I can't find it now...so I can investigate it.

I'm sure I'm missing something here

Thanks, was practicing the rotation as well. Reset Blender to factory settings as well. Here's the link to the model.
