Blender upload issue, mesh loses forward facing faces no matter what angle.

[LouiseDeBlois]

Blender file:

 

 

What it appears like on sl: (tinted to be shown easier)

What have i been doing wrong? Is it a issue with uploading?

 

The bow itself was mirrored in blender.... always had this issue :(

Well, I can't really see what is wrong in the SL version, but if the issue is faces not showing, then you just need to flip those normals, or recalculate the normals.

[LouiseDeBlois]

The issue is, whatever side you look at, the faces which are infront, turn invisible, only reveling those behind. 

 

so if i went behind this, the faces facing me will turn invisible, while the sides in the images will be shown again... in short, i can only see the inside of the faces.... no idea how to flip/fix this

[Drongle McMahon]

Yes. Turn on backface culling in Blender to see one-sided faces as in SL. That makes it easy to spot inverted normals.

[LouiseDeBlois]

Where is "Backface culling"? Sorry ahah, I am what one would call a blender noob

[Drongle McMahon]

Oh. From your pictures, it appears you have a LOT of triangles. What is the triangle count in the uploader. If it goes too high (>174752) , you will lose triangles.

[LouiseDeBlois]

Ahhh, so the blender file is correct, but the amount of triangles i am allowing is to low/high?

 

What would be the suggested amount?

[Drongle McMahon]

In Blnder, faces are rendered two-didd bu default. That means you see them even if they are facing the wrong way (inverted normals). In the Properties panel on the right of the 3D view, in the "Display" section, there is a checkbox for Backface Culling. That changes it to display only one side of the faces, the one the normal sticks out from, as is always the case in SL. The back side is then invisible. You can also see the normals by clicking the right hane of the two little buttons under "Normals". Flip the by selecting the faces and doing Mesh->Normals-<Flip. Or you can use the recalculate menu option instead.

Triangles .... I put the limit in the post, but that is far more than you should need anyway. The effective limit is 21844 per material. More than that and the uploader creates secret materials which can give you a variety of problems. At 174752, it drops any further triangles. I don't think this is you problem, although you don't really need so many. More likely it's the normals. Use smooth shaded surfaces rather than extra faces to get smooth appearance. That will save LI and gpu load as well.

thanks

 

On blender i done the backface culling, and it is now showing the same thing i get on sl. 

 

Can you say how to fix this issue? Not sure what you mean about flipping etc

[Drongle McMahon]

Select the faces that are missing, then from the menu do Mesh->Normals->Flip Normals

[LouiseDeBlois]

You, are a life saver *bows* thanks you both for all the help x Wish i could thank you more

[Medhue Simoni]

Sometimes, a quick easy fix can be to recalculate normals.
