 |
|
I've made furniture before in sketchup but never tried to use opacity, was just wondering if it is?
Would I have to create like a square in sketchup then just use a square opacity to show what I wanted to show in the client? What about a curved cyclinder like object would I be able to use opacity there?

Only use solid materials in SketchUp, then apply opacitys in Create Mode in the normal way.
In SketchUp we just build models, texturing effects are carried out after exporting to imvu.
The opacity function in the paintbucket window of SketchUp should only be used as an aid to see what you are doing, or for warehouse models.

The only advantage that using a Transparent Texture, unlike IMVU SketchUp does not use Pre-Historic Rendering Methods that need Opacity Maps, is that MeshOut can Identify Transparent Textures and will creat a .XRF File for them with Slots for the Diffuse Texture and the Opacity Map.

Thanks.
I tried using opacity in the client and it worked fine, one thing though I made the shape with one material in sketchup but in client when I use opacity it just repeats it all over the object so I'm not getting the effect I wanted. How can I make it think that something is one object and that it shouldn't tile the opacity?

Thanks I'd never even heard of that. I'll have a look at the tut and give it a go when I'm not so busy. Redoing icons takes so long.

You're welcome
The tut simply put in words:
Red pin grabbed and snapped to bottom left corner first.
Green pin grabbed and dragged until it snaps to the bottom right corner.
Blue pin grabbed and dragged until it snaps to the top left corner.
Avoid using the yellow pin, it "skews" the material ... only materials pinned with perfect 90 degree corners will export correctly. (-edit to add- 90º, unless both sets of sides are perfectly parallel, thanks Erika)

Not quite right. You may freely distiort this 90 degree perfection with the blue pin, it is allowed and works fine in CM.
So, not the cornes have to be 90 degree but the opposite sides have to be parallel.

I see what you're saying but this only applies when both sets of sides are parallel, a trapezoid, does not export well.
As the OP is new to pinning, it is best to learn basically pinning a rectangular or square shape, and then experimenting with more advancements.

It is a Well Proven and Recoznized Fact that Meshout Struggles to export Valid Texture Placement Information for Textures that are Not Pure Rectangles.
Why would anyone want to risk producing a Sub-Standard Product when it is Relatively Easy to Accurately Size and Pin Textures in SketchUp? |

As you can see here, the parallelogram (or rhombus) and the square export perfectly ... the trapezoid does not.
It is not necessary to touch the yellow pin to locate a material correctly on a parallelogram, only a trapezoid, therefore I maintain that unless experienced you should avoid touching the yellow pin altogether.

^ This is exactly why I want to keep things simple ... we end up answering the same question "Why don't my textures look like they do in SketchUp" every day.
Once you have experience Erika, yes it's good to push the envelope, just please don't confuse the issue lol.

Well, the material I was trying to get opacity for is circular so that's not good then lol.
So how would it work on a circular material?
Also in sketchup it's positioned fine but when I put it into CM it is rotated wrong and even with the rotate tool it doesn't go the correct way? How do I make it position itself like it is in sketchup?
